matters they are being asked to consider.
 
If you are a stockholder of Warnaco, you are being asked, at Warnaco's special
meeting of stockholders, to approve the issuance of Warnaco shares in connection
with our acquisition of Designer Holdings. These issuances include the merger,
the exchange in which we acquired 51.3% of Designer Holdings and the conversion
of Designer Holdings' outstanding convertible debentures. The Board of Directors
of Warnaco recommends a vote 'FOR' the issuance of such shares. YOUR VOTE IS
VERY IMPORTANT.
 
If you are a stockholder of Designer Holdings, you are being asked, at Designer
Holdings' special meeting of stockholders, to approve and adopt the merger
agreement and the merger. The Board of Directors of Designer Holdings recommends
a vote 'FOR' the approval and adoption of the merger agreement.
 
If the merger is completed, Designer Holdings stockholders will receive 0.324 of
a Warnaco share for each Designer Holdings share. Warnaco stockholders will
continue to own their existing shares after the merger.

THE OUTSTANDING SHARES, IN FAVOR OF THE MERGER. THIS VOTE WILL BE SUFFICIENT TO

proposal submitted to stockholders at your meeting by completing and mailing the

you appear in person.

                             QUESTIONS AND ANSWERS
                                ABOUT THE MERGER
 
Q: Why are the two companies proposing the merger?
 
A: This merger means that you will have a stake in one of the world's leading
   designers, manufacturers and marketers of women's intimate apparel, menswear
   and accessories. Warnaco already owns the trademarks worldwide for Calvin
   Klein men's and women's underwear and licenses the Calvin Klein trademarks
   worldwide for men's accessories. The acquisition will add to Warnaco's assets
   a 40-year extendable license for the Calvin Klein Jeans and Calvin Klein
   Khakis labels for men and women in North, South and Central America. To
   review the reasons for the merger in greater detail, see pages 20 through 23.
 
Q: Doesn't Warnaco already own Designer Holdings?
 
A: Warnaco recently acquired a majority of the outstanding shares of Designer
   Holdings common stock from Designer Holdings' principal stockholder at the
   same exchange ratio proposed for the merger. Pursuant to the merger agreement
   between Warnaco and Designer Holdings, Warnaco intends to acquire the rest of
   Designer Holdings through the merger. See 'The Merger Agreement -- Conditions
   to the Merger' on page 57.
 
Q: When are the special meetings?
 
A: Both the Warnaco and the Designer Holdings meetings will take place on
   December 12, 1997.
 
Q: What do I need to do now if I am not planning on attending the special
   meetings?
 
A: After carefully reading and considering the information contained in this
   joint proxy statement/prospectus, please fill out and sign your proxy card.
   Then mail your signed proxy card in the enclosed return envelope as soon as
   possible, so that your shares may be represented at the appropriate
   stockholder meeting.
 
Q: What do I do if I want to change my vote?
 
A: Just send in a later-dated, signed proxy card to your company's secretary
   before your meeting or attend your meeting in person and vote.
 
Q: Should I send in my stock certificates now?
 
A: No. After the merger is completed we will send Designer Holdings stockholders
   written instructions for exchanging their share certificates. Warnaco
   stockholders will keep their existing certificates.
 
Q: What will I receive in the merger?
 
A: When the merger closes, Designer Holdings stockholders will receive 0.324 of
   a share of Warnaco common stock for each share of Designer Holdings common
   stock. We will not issue fractional shares of Warnaco common stock. Instead,
   Designer Holdings stockholders will receive a check in the amount of the net
   proceeds from the sale of those shares in the open market.
 
   If you currently own shares of Warnaco common stock, then you will continue
   to hold those shares after the merger.
 
Q: What are the tax consequences to stockholders of the merger?
 
A: The exchange of shares by Designer Holdings stockholders will be tax-free for
   federal income tax purposes, except for taxes on cash received in exchange
   for any fractional shares. The merger will be tax-free to Warnaco
   stockholders for federal income tax purposes. To review the federal income
   tax consequences to stockholders in greater detail, see page 37.
 
Q: When do you expect the merger to be completed?
 
A: We expect to complete the merger before the end of 1997. We are working
   towards completing the merger as quickly as possible and expect to do so
   shortly after the special meetings.

                                 THE COMPANIES
 
THE WARNACO GROUP, INC.
90 Park Avenue
New York, New York 10016
(212) 661-1300
 
     Warnaco and its subsidiaries design, manufacture and market a broad line of
women's intimate apparel, such as bras, panties and sleepwear, and men's
sportswear, underwear and accessories, all of which are sold under such
internationally recognized owned and licensed brand names as Warner's'r',
Olga'r', Lejaby'r', Valentino Intimo'r' and Chaps by Ralph Lauren'r'.
 
     Warnaco owns the trademarks worldwide for Calvin Klein'r' men's and women's
underwear and sleepwear and licenses the Calvin Klein trademarks worldwide for
men's accessories.
 
DESIGNER HOLDINGS LTD.
1385 Broadway
New York, New York 10018
(212) 556-9600
 
     Designer Holdings, which develops, contracts for the production of and
markets designer jeanswear and sportswear for men, women, juniors and petites,
has a 40-year extendable license from Calvin Klein, Inc. to develop, contract
for the production of and market designer jeanswear and sportswear collections
in North, South and Central America under the Calvin Klein Jeans'r', CK/Calvin
Klein Jeans'r' and CK/Calvin Klein/Khakis'r' labels.
 
                                    OVERVIEW
 
     The merger is the second step of a two-step transaction in which Warnaco
will acquire all the outstanding common stock of Designer Holdings. On October
14, 1997, Warnaco acquired a majority of the outstanding shares of Designer
Holdings common stock from New Rio, L.L.C., formerly the majority stockholder of
Designer Holdings, in exchange for 5,340,773 shares of Warnaco common stock at
the 0.324 exchange ratio. Upon completion of the merger, Designer Holdings will
become a wholly owned subsidiary of Warnaco.
 
                        WARNACO'S REASONS FOR THE MERGER
 
     Warnaco believes that the acquisition offers an excellent opportunity to
build value for its stockholders. Warnaco's strategy is to build its global
businesses based on highly recognized brand names worldwide, to maximize the
value of its business by increasing its product distribution and to improve its
manufacturing efficiency and reduce costs. The acquisition of Designer Holdings
fits within this strategy because:
 
      The Calvin Klein Jeans and Khaki labels are among the most highly desired
      and successful labels in the North, South and Central America jeanswear
      and casual sportswear markets, and complement Warnaco's existing product
      lines.
 
      Warnaco has already demonstrated success with the Calvin Klein brand,
      growing the underwear, sleepwear and accessories businesses from
      approximately $55 million in sales in 1993 to $255 million in 1996.
 
      Warnaco believes the combination will add to its earnings in the first
      full year of combined operations, after taking into account estimated cost
      savings. Warnaco expects to achieve these cost savings principally through
      lowering distribution costs, eliminating public company expenses and
      streamlining operational, financial and administrative functions. Warnaco
      notes that achieving these earnings, cost savings and synergies is subject
      to certain risks as discussed in the sections 'Risk Factors' and
      'Cautionary Statement Concerning Forward-Looking Statements' on pages 13
      and 36.
 
      Warnaco believes it can expand Designer Holdings' share of the knit and
      woven tops market, and increase Designer
Hold-
 
                                       2

      ings' khaki and non-jeans pants business, as well as improve the results
      of operations of Designer Holdings.
 
     To review Warnaco's reasons for the merger in greater detail, see pages 20
through 22.
 
                   DESIGNER HOLDINGS' REASONS FOR THE MERGER
 
     Designer Holdings believes that the merger is fair to and in the best
interests of its stockholders for, among others, the following reasons:
 
      The merger provides Designer Holdings stockholders with the opportunity to
      benefit from the strategic fit between Warnaco and Designer Holdings,
      including the opportunity for cost savings, enhanced brand presentation
      and the potential for appreciation in the value of Warnaco's shares as a
      result of the merger, and to participate in any growth in the combined
      company.
 
      The Designer Holdings Board has determined, following a review of
      potential alternatives to the merger and the likelihood of successfully
      pursuing such alternatives on terms and conditions at least as favorable
      to stockholders as the merger, that the merger is more favorable to
      Designer Holdings' stockholders than any such alternative.
 
      The exchange ratio in the merger represented, on the last trading day
      prior to the public announcement of Warnaco's proposal on September 16,
      1997, a 17.29% premium to the closing price of Designer Holdings common
      stock based on a closing price for Designer Holdings common stock of
      $9.375 per share and a closing price for Warnaco common stock of $33.9375
      per share on such date, and, based on the opinion of Merrill Lynch as
      described under 'The Merger -- Opinion of Merrill Lynch' on page 28, is
      fair from a financial point of view to Designer Holdings' stockholders
      other than Warnaco, New Rio and their respective affiliates.
 
     To review Designer Holdings' reasons for the merger in greater detail, see
pages 22 through 25.
                              THE SPECIAL MEETINGS
 
     The record date for each special meeting is the close of business on
October 14, 1997. At the Warnaco meeting, Warnaco stockholders will be asked to
approve the issuance of Warnaco shares in the merger, the exchange with New Rio
and upon any conversions of Designer Holdings' outstanding convertible
debentures. At the Designer Holdings meeting, Designer Holdings stockholders
will be asked to approve and adopt the merger agreement and the merger.
 
     To review the details of the special meetings and the votes to be taken,
see pages 61 through 64.
 
                        RECOMMENDATIONS TO STOCKHOLDERS
 
TO WARNACO STOCKHOLDERS:
 
     The Warnaco Board believes that the merger is fair to you and in your best
interest and recommends that you vote FOR the proposal to approve the described
issuances of Warnaco shares in connection with Warnaco's acquisition of Designer
Holdings.
 
TO DESIGNER HOLDINGS STOCKHOLDERS:
 
     The Designer Holdings Board believes that the merger agreement and the
merger are fair to you and in your best interest and recommends that you vote
FOR the proposal to approve and adopt the merger agreement and the merger.
 
STOCKHOLDER VOTE REQUIRED TO APPROVE THE MERGER (PAGE 62)
 
     The affirmative vote of a majority of the shares of Warnaco common stock
present or represented by proxy at the Warnaco meeting is required to approve
the described issuances of Warnaco shares in connection with Warnaco's
acquisition of Designer Holdings. Failure to obtain the required stockholder
approval will not have any effect on the exchange with New Rio, which has
already occurred. Collectively, executive officers, directors and affiliates
of Warnaco (which does not include New Rio and its members) own 17% of the
outstanding Warnaco shares.
 
     The affirmative vote of a majority of the outstanding shares of Designer
Holdings com-
 
                                       3
 


<PAGE>

<PAGE>
mon stock is required to approve and adopt the merger agreement and the merger.
Collectively, executive officers, directors and affiliates of Designer Holdings
(including Warnaco) own 52.1% of the outstanding Designer Holdings shares.
 
     WARNACO, WHICH OWNS 51.3% OF DESIGNER HOLDINGS OUTSTANDING COMMON STOCK,
WILL VOTE ALL ITS SHARES IN FAVOR OF THE MERGER. SUCH VOTE WILL BE SUFFICIENT TO
APPROVE THE MERGER. ACCORDINGLY, NO ACTION BY ANY OTHER DESIGNER HOLDINGS
STOCKHOLDER IS NECESSARY TO APPROVE THE MERGER. Warnaco also controls a majority
of the Designer Holdings Board. Even if the merger is not completed, Warnaco
will have the ability to control the Designer Holdings Board and the vote on
corporate actions requiring stockholder approval, and thus effectively control
the direction and policies of Designer Holdings.
 
                                   THE MERGER
 
     The merger agreement is attached as Annex A to this Joint Proxy Statement/
Prospectus. We encourage you to read the merger agreement, which is the legal
document that governs the merger. The exchange agreement, which is the document
pursuant to which Warnaco acquired its Designer Holdings shares, is attached as
Annex B to this Joint Proxy Statement/Prospectus, and we urge you to read that
as well.
 
WHAT DESIGNER HOLDINGS STOCKHOLDERS WILL RECEIVE (PAGE 52)
 
     When the merger closes, each Designer Holdings stockholder will receive
0.324 of a share of Warnaco common stock in exchange for each share of Designer
Holdings common stock. Calculated at the market price of Warnaco common stock as
of the close of business on November 13, 1997 of $26 15/16 per share, Designer
Holdings stockholders will receive $8.728 worth of Warnaco common stock for
each share of Designer Holdings common stock. Each holder otherwise entitled to
receive fractional shares will receive such holder's pro rata share of the cash
proceeds from the sale in the market of all such fractional shares, net of sale
expenses.
 
     Designer Holdings stockholders should not send in their stock certificates
for exchange until instructed to do so after the merger is completed.
WHAT WARNACO STOCKHOLDERS WILL HOLD AFTER THE MERGER
 
     Warnaco stockholders will continue to own their existing shares after the
merger. Warnaco stockholders should not send in their stock certificates in
connection with the merger.
 
OWNERSHIP OF WARNACO AFTER THE MERGER
 
     Warnaco will issue approximately 5.1 million Warnaco shares to Designer
Holdings stockholders in the merger. These shares will represent approximately
8% of the outstanding Warnaco shares after the merger, in addition to the 9%
held by New Rio as a result of the 5,340,773 shares issued in the share
exchange. This information is based on the number of shares of Warnaco and
Designer Holdings common stock outstanding on October 14, 1997 and does not take
into account shares issuable upon the exercise of stock options or convertible
securities.
 
BOARD OF DIRECTORS AND MANAGEMENT OF WARNACO AFTER THE MERGER
 
     The existing board of directors and management of Warnaco will continue in
office upon completion of the merger. Arnold H. Simon will continue in his
position as President and Chief Executive Officer of the Designer Holdings
subsidiary of Warnaco.
 
INTERESTS OF OFFICERS AND DIRECTORS IN THE MERGER
 
     When considering the Designer Holdings Board's recommendation that Designer
Holdings stockholders vote in favor of the merger, Designer Holdings
stockholders should be aware that 19 Designer Holdings officers and key
employees, as well as all five directors at the time the merger agreement was
approved, have indemnification rights, employment agreements, stock options
and/or other agreements that provide them with interests in the merger that are
different from, or in addition to, other Designer Holdings stockholders. Arnold
H. Simon, the President and Chief Executive Officer of Designer Holdings, was
paid, upon completion of the exchange and in connection with the termination of
his prior employment agreement with Designer Holdings, approximately $7.8
million
 
                                       4

less approximately $2.9 million in withholding and other taxes and $2.3 million
in loans and other amounts owed by Mr. Simon to Designer Holdings. In addition,
all but one of the directors who voted to approve the merger and the share
exchange were related to New Rio.
 
     Please see pages 49 through 51 for more information concerning these
arrangements.
 
CONDITIONS TO THE MERGER (PAGE 57)
 
     The completion of the merger depends upon meeting or waiver of a number of
conditions, including the following:
 
     (1) obtaining the approval of the stockholders of Warnaco and Designer
         Holdings;
 
     (2) there being no law or court order that prohibits the merger;
 
     (3) the Warnaco shares to be issued in the merger having been approved for
         listing on the New York Stock Exchange, subject to official notice of
         issuance; and
 
     (4) receipt of opinions of counsel to both Warnaco and Designer Holdings
         that the merger will be tax-free to Designer Holdings and its
         stockholders.
 
Except as set forth above, the closing of the merger is not subject to any other
conditions. Certain of the conditions to the merger, but not (1), (2) or (3)
above, may be waived by the company entitled to assert the condition.
 
TERMINATION OF THE MERGER AGREEMENT (PAGES 58 - 59)
 
     Either Warnaco or Designer Holdings can terminate the merger agreement if
both companies agree or if any of the following occurs:
 
     (1) we do not complete the merger by June 30, 1998;
 
     (2) the stockholders of either Warnaco or Designer Holdings do not give the
         required stockholder approvals; or
 
     (3) a law or court order permanently prohibits the merger.
 
A party cannot terminate the merger agreement pursuant to paragraph (1) above if
that party is in breach of its obligations under the merger agreement.
 
     Also, Designer Holdings may terminate the merger agreement if the Warnaco
Board changes, in a manner adverse to Designer Holdings, its recommendation to
the Warnaco stockholders.
 
TERMINATION FEES AND EXPENSES (PAGES 40, 59)
 
     The merger agreement requires Designer Holdings to pay Warnaco a
termination fee of $12.5 million in cash, plus out-of-pocket transaction
expenses of up to $3 million, if (a) it becomes publicly known that a third
party has proposed to acquire more than 15% of Designer Holdings, (b) the merger
agreement is terminated because of the failure to obtain the required vote of
Designer Holdings stockholders to approve the merger by June 30, 1998, and (c)

termination. In connection with the settlement of certain stockholder
litigation, the termination fee is expected to be reduced to $6.25 million.

of Lazard Freres & Co. LLC as to the fairness of the exchange ratio in
connection with the share exchange and the merger, taken as a whole, to Warnaco

 (a) In fiscal year 1993, Warnaco decided to discontinue a portion of its men's
     manufactured dress shirt and neckwear business segment. This resulted in a
     non-recurring charge of $19.9 million. Also, Warnaco incurred a $2.6
     million non-recurring charge associated with a previously discontinued
     business. The total non-recurring charge recorded in fiscal year 1993 was
     $22.5 million (or $0.56 per share). In fiscal year 1994, Warnaco incurred a
     $3 million charge (or $0.07 per share) related to the California
     earthquake.
 
 (b) Fiscal year 1993 includes a $10.5 million charge (or $0.26 per share) for
     the cumulative effect of Warnaco changing its method of accounting for
     post-retirement benefits other than pensions.
 
 (c) Income for fiscal year 1994 reflects the benefits of using Warnaco's net
     operating loss carryforward to offset Warnaco's federal income tax
     provision. Income before non-recurring items, after giving effect to a full
     tax provision at Warnaco's effective income tax rate of 38%, would have
     been $41.1 million (or $1.00 per share).
 
 (d) Effective with fiscal year 1995, Warnaco adopted Statement of Position 93-7
     ('SOP 93-7'), dealing with certain types of advertising and promotion
     costs. SOP 93-7 requires, among other things, that certain costs, which had
     previously been deferred for amortization against future revenues, be
     currently expensed. As a result of adopting SOP 93-7, Warnaco incurred a
     special charge of $11.7 million for advertising costs that would otherwise
     have been deferred ($7.3 million, net of income tax benefits, or $0.16 per
     share) in fiscal year 1995.
 
 (e) Fiscal year 1996 includes non-recurring charges related to the sale of
     Warnaco's Hathaway'r' dress shirt operations of $46.0 million,
     consolidation and re-alignment of Warnaco's intimate apparel division of
     $72.1 million and other items of $20.4 million. Total non-recurring items
     were $138.5 million ($88.8 million net of income tax benefits of $49.7
     million, or $1.66 per share).
 
 (f) The nine months ended October 5, 1996 includes non-recurring charges
     related to the sale of Warnaco's Hathaway dress shirt operations,
     consolidation and re-alignment of Warnaco's intimate apparel division and
     other items totalling $138.5 million ($88.8 million net of income tax
     benefits of $49.7 million, or $1.66 per share).

(1) The Predecessor Companies consisted of five separate entities commonly
    controlled and managed by Mr. Arnold H. Simon, the President and Chief
    Executive Officer of Designer Holdings, and Mr. Stephen Huang, a former
    business associate of Mr. Simon. For more information, see Note 1 to the
    audited financial statements of Designer Holdings which are incorporated by

    impairment charge of $14.7 million ($12.8 million net of an income tax
    benefit of $1.9 million, or $.40 per share) related to (i) the
    discontinuation of the Bill Blass license, including the write-down of
    goodwill and other costs of terminating the business, (ii) a loss on the
    sublease of Designer Holdings' North Arlington facility and (iii) the write-
    down of shop-in-shop fixtures that do not meet new design requirements.

                          SELECTED UNAUDITED PRO FORMA
                         COMBINED FINANCIAL INFORMATION
 
     Warnaco and Designer Holdings are providing the following unaudited pro
forma financial information to give you a picture of what the results of
operations and financial position of Warnaco and Designer Holdings would have
looked like, absent any operational or other changes, had our businesses been
combined for the periods and at the dates indicated. This information is
provided for illustrative purposes only and does not show what our results of
operations or financial position would have been if the merger had actually
occurred on the dates assumed. This information also does not indicate what our
future operating results or consolidated financial position will be. Please see
'Unaudited Pro Forma Combined Financial Statements' on page 42 for a more
detailed explanation of this analysis.
 
PURCHASE ACCOUNTING TREATMENT
 
     The merger will be accounted for as a purchase of Designer Holdings by
Warnaco, and the selected unaudited pro forma combined financial information
reflects this method of accounting.
 
     We have prepared the unaudited pro forma combined balance sheet by
adjusting the balances to reflect the estimated fair value, including goodwill,
of the assets and liabilities of Designer Holdings. Upon completion of a
comprehensive review of such values, further adjustments are likely.
 
     The unaudited pro forma combined statements of income have been prepared by
adding the historical operations of Designer Holdings to the historical
operations of Warnaco and adjusting for certain known changes such as changes in
amortization and interest expense to reflect the adjustment of the Designer
Holdings net assets to their estimated fair value.
 
PERIODS COVERED
 
     The unaudited pro forma combined statements of income combine Warnaco's
results for its fiscal year 1996 and for the nine months ended October 4, 1997
with Designer Holdings' results for its fiscal year 1996 and the nine months
ended September 30, 1997, giving effect to the merger as if it had occurred as
of January 7, 1996.
 
     The unaudited pro forma balance sheet combines Warnaco's balance sheet at
October 4, 1997 and the estimated fair value of Designer Holdings' net assets at
September 30, 1997, giving effect to the merger as if it had occurred as of
October 4, 1997.

                  COMPARATIVE UNAUDITED PER SHARE INFORMATION
 
     We have summarized below the per share information for our companies on an
historical, pro forma combined and equivalent basis. Warnaco's historical data
is for the periods and as of the dates indicated below, while Designer Holdings
historical data is based on the nine month period ended September 30, 1997, and
the year ended December 31, 1996. You should read this information in
conjunction with our historical financial statements (and related notes)
contained in the annual and quarterly reports and other information that we have
filed with the Securities and Exchange Commission. See 'Where You Can Find More
Information' on page 69. You should also read this information in connection
with the Unaudited Pro Forma Combined Financial Statements set forth on pages 42
through 48. The Warnaco pro forma information gives effect to the merger
accounted for as a purchase, assuming that 0.324 of a share of Warnaco common
stock is issued for each share of Designer Holdings common stock outstanding.
The pro forma information also assumes a market value of $33 15/16 per share of
Warnaco common stock. Designer Holdings equivalent share amounts are calculated
by multiplying the pro forma income per share, pro forma book value per share
and Warnaco's historical per share dividend by the exchange ratio of 0.324 of a
share of Warnaco common stock so that the per share amounts equate to the
respective values for one share of Designer Holdings common stock. You should
not rely on the pro forma information as being indicative of the historical
results that we would have had or the future results that we will experience
after the merger.

                                  RISK FACTORS
 
     You should consider carefully the following factors, in addition to the
other information contained in this joint proxy statement/prospectus, before
voting on the merger and/or the issuance of shares of Warnaco common stock.
 
RISKS ASSOCIATED WITH THE APPAREL BUSINESS
 
     The apparel business is extremely competitive. The companies that compete
with Warnaco and Designer Holdings include manufacturers of all sizes, some of
which have greater financial resources than Warnaco. In addition, companies in
the apparel business may have different financial results during certain seasons
or during good or bad economic times. If the national or worldwide economy
weakens or there are uncertainties regarding future economic conditions or if
consumers in general spend less money, our companies' financial performance may
weaken. Over the past several years, Warnaco has expanded its channels of
distribution to decrease its dependence on any one retail channel.
 
DEPENDENCE ON OUR CHAIRMAN
 
     Warnaco believes that it benefits substantially from the leadership of
Linda J. Wachner, Warnaco's Chairman, President and Chief Executive Officer. The
loss of Mrs. Wachner's services could have a significant impact on Warnaco's
business and its future operations. In May 1991, Warnaco entered into an
employment agreement with Mrs. Wachner which will, unless extended, expire in
January 2002.
 
RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS
 
     General. The combined companies have subsidiaries in Canada and Mexico in
North America and throughout Western Europe and Asia which engage in sales,
manufacturing and marketing activities. The results of the combined companies'
operations in these countries will be influenced by the movement of foreign
currency exchange rates. With the exception of changes in the exchange rates of
the local currencies in which these subsidiaries operate, we do not believe that
these operations are subject to significantly different risks from our domestic
operations.
 
     Federal Regulation. Substantially all of Warnaco's Menswear Division's
sportswear products and a portion of Designer Holdings' products are
manufactured by contractors located outside the United States. These products
are imported and are subject to federal customs laws, which impose tariffs as
well as import quota restrictions. While importation of goods from certain
countries may be subject to embargo by United States customs authorities if
shipments exceed quota limits, Warnaco closely monitors import quotas and can,
in most cases, shift production to contractors located in countries with
available quotas or to domestic manufacturing facilities. The existence of
import quotas has not had a material effect on Warnaco's business.
 
DEPENDENCE ON LICENSES
 
     While Warnaco owns the Calvin Klein trademarks for men's and women's
underwear, it licenses the trademarks for Calvin Klein men's accessories, Chaps
by Ralph Lauren and other brands. In addition, Designer Holdings licenses the
trademarks for Calvin Klein Jeans and Khakis. Neither Warnaco nor Designer
Holdings is aware of any risk relating to the continued existence of this
license. The businesses relating to these licenses depend on the continued
existence of the licenses and the continuing value of the underlying name, such
as Calvin Klein or Ralph Lauren.

                                   THE MERGER
 
GENERAL
 
     Warnaco and Designer Holdings are furnishing this Joint Proxy
Statement/Prospectus to holders of Class A common stock, par value $0.01 per
share ('Warnaco Common Stock'), of The Warnaco Group, Inc., a Delaware
corporation ('Warnaco'), and holders of common stock, par value $0.01 per share
('Designer Holdings Common Stock'), of Designer Holdings Ltd., a Delaware
corporation ('Designer Holdings'), in connection with the solicitation of
proxies by the Warnaco Board to be voted at a special meeting of Warnaco
stockholders (the 'Warnaco Meeting') and by the Designer Holdings Board to be
voted at a special meeting of Designer Holdings stockholders (the 'Designer
Holdings Meeting'), and at any adjournments or postponements thereof (the
Warnaco Meeting and the Designer Holdings Meeting being referred to together as
the 'Meetings').
 
     At the Warnaco Meeting, holders of Warnaco Common Stock will be asked to
vote upon a proposal to approve the issuance of shares of Warnaco Common Stock
in the Merger, the Exchange and upon any conversions of certain convertible
debentures of Designer Holdings. See 'The Merger Agreement -- Treatment of TOPrS
and Convertible Debentures'. A possible consequence of such approval is that it
could be used by Warnaco and its directors as a defense against subsequent
claims relating to the Merger or the Exchange by any stockholder that votes its
shares in favor of such issuances. The affirmative vote of a majority of the
votes represented by the Warnaco shares present at the Warnaco Meeting, in
person or by proxy, and entitled to vote thereat, is required to approve such
issuances. Failure to obtain the required stockholder approval will not have any
effect on the Exchange, which has already occurred.
 
     At the Designer Holdings Meeting, holders of Designer Holdings Common Stock
will be asked to vote upon a proposal to approve and adopt an Agreement and Plan
of Merger, dated as of September 25, 1997 (the 'Merger Agreement'), among
Warnaco, Designer Holdings and WAC Acquisition Corporation, a Delaware
corporation and wholly owned subsidiary of Warnaco ('WAC'), and the Merger. The
affirmative vote, in person or by proxy, of the holders of a majority of the
Designer Holdings shares outstanding on the record date for the Designer
Holdings Meeting is required to approve and adopt the Merger Agreement and the
Merger. A copy of the Merger Agreement is attached hereto as Annex A.
 
     Neither Warnaco stockholders nor Designer Holdings stockholders are being
asked to approve the changes to the 6% Convertible Trust Originated Preferred
Securities (the 'TOPrS') issued by Designer Finance Trust and guaranteed by
Designer Holdings, or the $123,711,350 of Designer Holdings' 6% Convertible
Debentures Due 2016 (the 'Convertible Debentures') described under 'The Merger
Agreement -- Treatment of TOPrS and Convertible Debentures' and 'Description of
Warnaco Capital Stock -- Treatment of TOPrS'.
 
     Warnaco, which owns 51.3% of the outstanding Designer Holdings Common
Stock, will vote all its shares in favor of the Merger. Such vote will be
sufficient to approve the Merger. Accordingly, no action by any other Designer
Holdings stockholder is necessary to approve the Merger. To the extent that any
Designer Holdings stockholder other than Warnaco votes its shares in favor of
the Merger, Designer Holdings and its directors may use such approval as a
defense against possible claims by or on behalf of such stockholder relating to
the Merger.
 
     The Merger Agreement provides for the merger of WAC with and into Designer
Holdings (the 'Merger'), with Designer Holdings surviving the Merger as a wholly
owned subsidiary of Warnaco. The Merger will become effective at the time of
filing a Certificate of Merger with the Secretary of State of the State of
Delaware or at such later time as is specified in the Certificate of Merger
(such time being herein referred to as the 'Effective Time'), which is expected
to occur as soon as practicable after the last of the conditions precedent to
the Merger has been satisfied or waived.
 
     On October 14, 1997, pursuant to a Stock Exchange Agreement, dated as of
September 25, 1997 (the 'Exchange Agreement'), among Warnaco, New Rio, L.L.C., a
Delaware limited liability company and at the time the majority stockholder of
Designer Holdings ('New Rio'), and the
 
                                       14

members of New Rio, Warnaco acquired from New Rio and one of its former members
51.3% of the outstanding Designer Holdings Common Stock in exchange for newly
issued shares of Warnaco Common Stock representing approximately 9% of the
outstanding Warnaco shares (the 'Exchange'). A copy of the Exchange Agreement is
attached hereto as Annex B.
 
BACKGROUND OF THE MERGER
 
     In early 1995, representatives of Warnaco, New Rio, Charterhouse Equity
Partners II, L.P. ('CEP II'), one of two managing members of New Rio, and
Designer Holdings held exploratory discussions regarding a possible business
combination involving Warnaco and Designer Holdings. These discussions were
abandoned because the parties were not able to reach an understanding as to the
terms of any transaction.
 
     On August 14, 1997, at the suggestion of Arnold H. Simon, President, Chief
Executive Officer and a director of Designer Holdings, Linda J. Wachner,
Chairman, President and Chief Executive Officer of Warnaco, Merril M. Halpern,
Chairman and Chief Executive Officer of Charterhouse Group International, Inc.
('Charterhouse'), which indirectly controls CEP II, and Chairman of Designer
Holdings, and Mr. Simon agreed to meet in September 1997 to discuss a possible
business combination involving Warnaco and Designer Holdings.
 
     On August 22, 1997, at a meeting of the Warnaco Board, Mrs. Wachner
discussed with the Warnaco Board the advisability of pursuing a potential
business combination with Designer Holdings.
 
     On September 11, 1997, Mrs. Wachner and William S. Finkelstein, Warnaco's
Senior Vice President and Chief Financial Officer, met with Mr. Halpern, A.
Lawrence Fagan, President and Chief Operating Officer of Charterhouse and a
director of Designer Holdings, Mr. Simon and David Fidlon, Designer Holdings'
Senior Vice President and Controller, to discuss a possible transaction.
Following the execution of a confidentiality agreement on September 11,
Warnaco's management, legal advisors and accountants commenced a due diligence
review of Designer Holdings' operations, finances and corporate documents and
contracts. Following the execution of a separate confidentiality agreement,
Designer Holdings commenced its due diligence review of Warnaco on September 22,
1997.
 
     On September 16, 1997, Mrs. Wachner, Mr. Finkelstein and Stanley P.
Silverstein, Vice President, General Counsel and Secretary of Warnaco,
accompanied by representatives of Warnaco's outside counsel, Simpson Thacher &
Bartlett ('Simpson Thacher'), met with Messrs. Halpern, Fagan and Simon and John
J. Jones, Vice President, General Counsel and Secretary of Designer Holdings. At
this meeting, the parties negotiated, subject to the approval of the Warnaco and
Designer Holdings Boards, possible terms, including a possible price range, of a
transaction that could form the basis for an acquisition by Warnaco of Designer
Holdings.
 
     The Warnaco Board held a telephonic meeting on the afternoon of September
16 at which it authorized Mrs. Wachner and other executive officers of Warnaco
to negotiate the terms of a transaction in which Warnaco would acquire Designer
Holdings in a tax-free, stock-for-stock merger pursuant to which Designer
Holdings' stockholders would receive $11 worth of Warnaco Common Stock for each
share of Designer Holdings Common Stock, as had been proposed by Warnaco to
Designer Holdings in the course of the negotiations described above, subject to
(a) the receipt of an opinion from a nationally recognized investment banking
firm as to the fairness, from a financial point of view, to the Warnaco
stockholders of the consideration to be paid in the proposed transaction, (b)
the negotiation of definitive documentation and (c) the receipt of further Board
approval for the final negotiated terms of such a transaction. In addition, the
Warnaco Board also approved the execution of a 'standstill' agreement pursuant
to which both Designer Holdings and New Rio would agree, among other things,
that neither they nor their representatives would directly or indirectly solicit
competing bids to acquire Designer Holdings or the shares of Designer Holdings
Common Stock owned by New Rio until the earlier of the execution by Warnaco and
Designer Holdings of a definitive agreement relating to the proposed transaction
and 11:59 p.m., New York time, on September 23, 1997 (the 'Standstill
Agreement').

     The Designer Holdings Board also met on the afternoon of September 16 to
consider a possible transaction in which Warnaco would acquire Designer Holdings
on the terms described in the preceding paragraph. The Designer Holdings Board
determined to retain Merrill Lynch, Pierce, Fenner & Smith Incorporated
('Merrill Lynch') to advise it as to whether the proposed consideration to be
received by Designer Holdings' stockholders in the proposed merger is fair to
such stockholders from a financial point of view. Subject to (a) the receipt of
an acceptable opinion from Merrill Lynch with respect to the proposed
consideration, (b) the negotiation of definitive documentation and (c) the
receipt of further Board approval for the final terms of any such transaction,
the Designer Holdings Board authorized management to negotiate a transaction in
which Designer Holdings would be acquired by Warnaco for consideration with a
value of at least $11 per share. In addition, the Designer Holdings Board
approved the Standstill Agreement.
 
     On September 17, 1997, Warnaco, Designer Holdings and New Rio executed the
Standstill Agreement. Immediately thereafter, Warnaco and Designer Holdings
issued a joint press release announcing the proposed transaction, subject to the
conditions set forth in the preceding paragraphs, and stating that New Rio had
indicated its intention to support the proposed transaction.
 
     On September 18, 1997, Warnaco proposed to Designer Holdings and New Rio
the terms of a transaction that included (a) the issuance, in exchange for each
outstanding share of Designer Holdings Common Stock, of shares of Warnaco Common
Stock having a value of $11, (b) an agreement by New Rio to vote its Designer
Holdings shares in favor of the Merger and against any other competing
transaction, including following any termination of the Merger Agreement, as
well as the grant by New Rio to Warnaco of a proxy to support such agreement,
(c) a prohibition on transfers by New Rio of its Designer Holdings shares until
the consummation of the Merger, (d) a restriction on the ability of Designer
Holdings and New Rio to solicit competing transactions to acquire Designer
Holdings or the Designer Holdings shares owned by New Rio and (e) the obligation
of Designer Holdings to pay to Warnaco a $12.5 million termination fee and
reimburse Warnaco for up to $3 million in transaction expenses in the event of
termination of the merger agreement under certain other circumstances. See 'The
Merger Agreement' and 'The Exchange Agreement'.
 
     On September 19, 1997, Warnaco retained Lazard Freres & Co. LLC ('Lazard
Freres') to deliver an opinion to the Warnaco Board as to whether the
consideration to be paid by Warnaco in connection with the proposed transactions
was fair to Warnaco and its stockholders from a financial point of view.
 
     Also on September 19, New Rio and Warnaco began to negotiate alternative
means of ensuring New Rio's vote in favor of the proposed merger in the event
Warnaco and Designer Holdings were to enter into a merger agreement, including,
among other things, granting Warnaco an option to purchase all or a portion of
the New Rio shares.
 
     On September 21, 1997, Warnaco informed New Rio and Designer Holdings that
it would be prepared to seek Board approval of an agreement to acquire all
shares of Designer Holdings Common Stock owned by New Rio promptly following the
expiration or early termination of the waiting period under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the 'HSR
Act'), and the satisfaction of other customary conditions, with each Designer
Holdings share owned by New Rio to be exchanged for shares of Warnaco Common
Stock having a value of approximately $11. On this basis, representatives of
Warnaco, Designer Holdings and New Rio began to negotiate the terms of the
definitive documentation for the Merger and the Exchange. In connection with
such discussions, representatives of Designer Holdings asked whether Warnaco was
willing to pay greater consideration to Designer Holdings' public stockholders
in the Merger. Warnaco advised such representatives that it would not. Also on
September 21, 1997, Mrs. Wachner and Mr. Simon reached a tentative agreement on
the terms of Mr. Simon's continued employment.
 
     On September 22, 1997, Warnaco proposed to Designer Holdings and New Rio
the terms of a merger agreement and stock exchange agreement pursuant to which,
among other things and in
 
                                       16
 

<PAGE>

<PAGE>
addition to the terms described above, (a) Warnaco would acquire each Designer
Holdings share owned by New Rio in exchange for shares of Warnaco Common Stock
having a value of approximately $11, (b) the closing of such transaction would
be subject to, among other things, (i) the Designer Holdings shares owned by New
Rio representing a majority of the outstanding shares of Designer Holdings
Common Stock at the time of such closing, (ii) Designer Holdings having taken
all necessary action so that immediately upon such closing Warnaco would be able
to designate a majority of directors on the Designer Holdings Board and (iii)
Designer Holdings having taken all necessary action so that the record date for
the Designer Holdings Meeting would occur immediately following the closing of
the Exchange so that Warnaco would be the holder of record of a majority of the
outstanding shares of Designer Holdings Common Stock for purposes of the
Designer Holdings Meeting, (c) Designer Holdings would agree that in the event
that the Designer Holdings shares acquired by Warnaco in the Exchange ceased to
constitute a majority of the outstanding shares of Designer Holdings Common
Stock, Designer Holdings would issue to Warnaco for $11 in cash per share such
number of Designer Holdings shares as would be necessary for Warnaco to own a
majority of Designer Holdings' outstanding shares, (d) Warnaco would agree to
vote all of its shares of Designer Holdings Common Stock in favor of the Merger,
(e) Warnaco would provide New Rio, after the Effective Time, with the same
liquidity as the public stockholders of Designer Holdings, by agreeing to file
and maintain effective a shelf registration statement to facilitate resales of
the shares of Warnaco Common Stock acquired by New Rio in the Exchange, (f) New
Rio and its members (collectively, the 'Sellers') would be treated no better
than the public stockholders of Designer Holdings, including through an
agreement by the Sellers (i) not to transfer any shares of Warnaco Common Stock
received in the Exchange until the earlier of the termination of the Merger
Agreement and the consummation of the Merger, (ii) to waive their right to
receive any dividend declared by Warnaco and payable to holders of record after
consummation of the Exchange and prior to the consummation of the Merger and
(iii) not to take any action directly or indirectly intended to direct,
influence or control the management or Board of Directors of Warnaco, (g) CEP II
and Mr. Simon would agree not to compete with Warnaco for a period of time in
any line of business of the type conducted by Warnaco at the time of entering
into such agreement or at the time of closing the Exchange and (h) following
consummation of the Exchange, all conditions to closing the Merger would be
eliminated other than the receipt of requisite stockholder approvals, absence of
any injunction, receipt of tax opinions and listing on the New York Stock
Exchange (the 'NYSE') of the Warnaco shares to be issued in the Merger. See 'The
Merger Agreement' and 'The Exchange Agreement'.
 
     The Warnaco Board held a meeting on September 22, 1997, which was attended
by representatives of Simpson Thacher, during which the Warnaco Board discussed
the revised structure of the proposed transactions and the status of the
negotiations. No formal action was taken at this meeting.
 
     Later that day, in order to ensure that the public stockholders of Designer
Holdings would receive per share consideration identical to that to be received
by New Rio, as well as to fix the number of shares to be issued by Warnaco,
Warnaco proposed to fix the exchange ratio for all shares of Designer Holdings
Common Stock to be acquired by Warnaco in the Exchange and the Merger. The
parties subsequently agreed to seek Board approval for a fixed ratio of 0.324 of
a share of Warnaco Common Stock for each Designer Holdings share (the 'Exchange
Ratio'), determined by dividing $11 by $33 15/16, the closing price of Warnaco
on the NYSE on September 16, 1997, which was the day the parties received Board
approval to negotiate definitive terms of the proposed transaction. In addition,
Designer Holdings determined to seek Board approval for an extension of the term
of the Standstill Agreement until 11:59 p.m., New York time, on September 26,
1997.
 
     Later in the afternoon on September 22, the Designer Holdings Board met,
together with its counsel, Skadden, Arps, Slate, Meagher & Flom LLP ('Skadden
Arps'), to further consider the proposed transaction. The Designer Holdings
Board reviewed various legal, tax, business and financial issues. The directors
also reviewed unsolicited preliminary contacts received from other inter-
 
                                       17

<PAGE>
ested parties, none of whom made any formal offers or proposals, potential
alternatives to the proposed transaction (including conducting a public auction,
entering into a transaction with another strategic buyer and continuing as an
independent company), the adequacy of the proposed consideration, as well as
advantages and disadvantages of a stock transaction compared with an all- or
part-cash transaction, and the risk that the Merger would not be consummated.
The directors discussed the fact that, since Warnaco would own a majority of the
Designer Holdings shares following consummation of the Exchange, if the Merger
were not subsequently consummated, there could be no assurance that Designer
Holdings' public stockholders would have an alternative means of selling their
shares at a premium. The directors, four of whom were affiliated with New Rio,
also noted that in such event the Exchange would be fully taxable to the
Sellers. After considering the foregoing, the Designer Holdings Board determined
that the strategic benefits and the value of Warnaco's offer were greater than
the anticipated value of any of the potential alternatives of the proposed
transaction, and resolved to continue negotiating a transaction and approved the
extension of the Standstill Agreement.
 
     On September 23, 1997, Warnaco, Designer Holdings and New Rio executed the
extension to the Standstill Agreement. In addition, New Rio and Designer
Holdings proposed the following changes and additions to Warnaco's proposed
terms: (a) any Designer Holdings shares issued to Warnaco to maintain Warnaco's
majority ownership of Designer Holdings would be paid for by Warnaco in cash in
an amount equal to the average value of 0.324 of a share of Warnaco Common Stock
during the five trading days prior to the date of such purchase; (b) certain
employees of Designer Holdings, none of whom were directors, would be paid
bonuses upon the consummation of the Merger aggregating $7 million (of which
half would be paid by each of Designer Holdings and New Rio); (c) one Seller
(owning 225,374 Designer Holdings shares) would be permitted to withdraw such
shares from New Rio, but remain a signatory to, and bound by the provisions of,
the Exchange Agreement; and (d) Mrs. Wachner would agree to vote all Warnaco
shares beneficially owned by her and outstanding on the record date for the
Warnaco Meeting in favor of the issuance of shares of Warnaco Common Stock in
connection with the transactions contemplated by the Merger Agreement, including
the Exchange and the Merger and upon the conversion of any of Designer Holdings'
outstanding convertible debentures. See 'The Merger Agreement' and 'The Exchange
Agreement'.
 
     On September 24, 1997, the Designer Holdings Board met, together with
representatives of Skadden Arps and Merrill Lynch, to further consider the
proposed Merger Agreement, the Exchange Agreement and the transactions
contemplated thereby. The Designer Holdings Board reviewed the status of the
negotiations, and Merrill Lynch presented a detailed valuation analysis of
Warnaco's proposal. Merrill Lynch also rendered its oral opinion (which was
subsequently confirmed in writing on September 25) to the effect that as of such
date, and based upon and subject to the assumptions, limitations and
qualifications in such opinion, the Exchange Ratio in the proposed Merger was
fair from a financial point of view to the Designer Holdings stockholders (other
than Warnaco, New Rio and their respective affiliates). For information on the
assumptions made, matters considered and limitations on the review by Merrill
Lynch, see ' -- Opinion of Merrill Lynch'. Stockholders are urged to read in its
entirety the opinion of Merrill Lynch, attached as Appendix D to this Joint
Proxy Statement/Prospectus. In addition, the directors discussed, with
management present, Designer Holdings' business, management, financial
performance and condition, strategic objectives, prospects and competitive
position, as well as industry conditions in general and the designer jeanswear
and sportswear businesses in particular. The directors again reviewed the
preliminary contacts Designer Holdings had received from other interested
parties. Skadden Arps then reviewed in detail the proposed Exchange Agreement
and Merger Agreement. In this connection, the Designer Holdings Board noted
that, among other things, the Merger Agreement would permit the Designer
Holdings Board, but only prior to the closing of the Exchange, to terminate the
Merger Agreement if it were to determine in its good faith judgment that a
proposed unsolicited alternative transaction were more favorable to the Designer
Holdings stockholders than the Merger Agreement and the Merger and, as a result
thereof, determined in
 
                                       18
 

<PAGE>

<PAGE>
good faith, based on the advice of outside counsel, that it was obligated by its
fiduciary obligations under applicable law to terminate the Merger Agreement.
The directors also noted that, despite the Designer Holdings Board's right to
terminate the Merger Agreement, the Exchange Agreement could not be terminated
in the event of such a termination. In this regard, the Designer Holdings Board
believed that it had no fiduciary duty to include a provision in the Merger
Agreement that would allow it to consider a more favorable unsolicited
transaction following the closing of the Exchange, particularly in light of New
Rio's support for the Merger. After full discussion, the Designer Holdings Board
unanimously determined that the Exchange Agreement, the Merger Agreement and the
Merger were fair to and in the best interests of Designer Holdings stockholders
(other than Warnaco, New Rio and their respective affiliates). The Designer
Holdings Board then approved the Exchange Agreement, the Merger Agreement and
the Merger and recommended that Designer Holdings stockholders vote to approve
and adopt the Merger Agreement and the Merger.
 
     On the evening of September 24, 1997, the Warnaco Board met, together with
representatives of Simpson Thacher and Lazard Freres. Simpson Thacher reviewed
the terms of the proposed transaction, including the proposed Merger Agreement
and Exchange Agreement, and Lazard Freres made a presentation that included a
discussion of its valuation methodologies and analyses used in arriving at its
fairness opinion. Lazard Freres delivered its oral opinion to the Warnaco Board
to the effect that, as of such date and based upon and subject to the
assumptions, limitations and qualifications in such opinion, the Exchange Ratio
in connection with the Exchange and the Merger, taken as a whole, was fair to
Warnaco and to Warnaco's stockholders from a financial point of view. Such
opinion was confirmed in writing at the time the Merger Agreement and the
Exchange Agreement were executed. For information on the assumptions made,
matters considered and limitations on the review by Lazard Freres, see
' -- Opinion of Lazard Freres & Co. LLC'. Stockholders are urged to read in its
entirety the opinion of Lazard Freres, attached as Appendix C to this Joint
Proxy Statement/Prospectus. The Warnaco Board (i) voted that the Merger
Agreement and the transactions contemplated thereby, including the issuance of
shares of Warnaco Common Stock in the Merger, the Exchange and upon any
conversions of the Convertible Debentures, are fair to and in the best interests
of Warnaco stockholders, (ii) approved the Merger Agreement and the Exchange
Agreement and (iii) recommended that the stockholders of Warnaco approve the
issuance of shares of Warnaco Common Stock in the Merger, the Exchange and upon
any conversions of the Convertible Debentures.
 
     Following the Board meetings, representatives of Warnaco, Designer Holdings
and New Rio finalized the Merger Agreement and the Exchange Agreement for
execution. The parties executed the Merger Agreement and the Exchange Agreement
(as well as an employment agreement between Warnaco and Mr. Simon) on the
evening of September 25, 1997 and immediately thereafter Warnaco and Designer
Holdings issued a joint press release publicly announcing the transaction.
 
     On October 14, 1997, Warnaco and the Sellers consummated the Exchange and
Warnaco became the holder of 16,483,868 shares of Designer Holdings Common
Stock, representing 51.3% of the outstanding Designer Holdings shares. Effective
upon the closing of the Exchange, Mr. Fagan and Debra Simon resigned from the
Designer Holdings Board, the size of the Designer Holdings Board was increased
to seven and Mrs. Wachner, Mr. Finkelstein, Andrew G. Galef and Joseph A.
Califano, Jr. (all four being current directors of Warnaco) were elected to the
Designer Holdings Board. Immediately following the closing of the Exchange, the
new Designer Holdings Board elected Mrs. Wachner Chairman of the Board and
appointed Messrs. Finkelstein and Silverstein as vice presidents of Designer
Holdings. Mr. Halpern, Mr. Simon and Peter Damon Brown have remained on the
Designer Holdings Board as continuing directors. See 'The Merger
Agreement -- Certain Covenants -- Board of Directors'.

WARNACO'S REASONS FOR THE MERGER; RECOMMENDATION OF THE WARNACO BOARD
 
     At a meeting of the Warnaco Board held on September 24, 1997, after careful
consideration, the Warnaco Board (i) voted that the Merger Agreement and the
transactions contemplated by the Merger Agreement, including the issuance of
shares of Warnaco Common Stock in the Merger, the Exchange and upon any
conversions of the Convertible Debentures, are fair to and in the best interests
of Warnaco stockholders, (ii) approved the Merger Agreement and the Exchange
Agreement and (iii) recommended that the stockholders of Warnaco approve the
issuance of shares of Warnaco Common Stock in the Merger, the Exchange and upon
any conversions of the Convertible Debentures. Because the number of Warnaco
shares issued in the Exchange did not exceed 20% of the outstanding Warnaco
shares prior to such issuance, such issuance did not require the approval of the
Warnaco stockholders, except to the extent considered together with the Warnaco
shares to be issued in the Merger and upon conversion of the Convertible
Debentures and the TOPrS. Therefore, any failure to obtain the requisite
stockholder approval of the Warnaco Merger Proposal will not have any effect on
the Exchange or the validity of the Warnaco shares issued in the Exchange.
 
Warnaco's Reasons for the Merger
 
     Warnaco believes that the acquisition of Designer Holdings offers an
excellent opportunity to build value for its stockholders. Warnaco's strategy is
to build its global businesses based on highly recognized brand names worldwide,
to maximize the value of its business by increasing its product distribution and
to improve its manufacturing efficiency and reduce costs. The acquisition of
Designer Holdings fits within this strategy because:
 
      The Calvin Klein Jeans and Khaki labels are among the most highly desired
      and successful labels in the North, South and Central America jeanswear
      and casual sportswear markets, and complement Warnaco's existing product
      lines.
 
      Warnaco has already demonstrated success with the Calvin Klein brand,
      increasing the underwear, sleepwear and accessories businesses from $55
      million in sales in 1993 to $255 million in 1996.
 
      Warnaco believes the combination will contribute approximately $.10 per
      share to Warnaco's earnings in the first full year of combined operations,
      after taking into account approximately $14 million of estimated net cost
      savings in such first year ($19 million of savings in selling, general and
      administrative expense, net of $5 million in amortization of goodwill), as
      estimated by management of Warnaco. Warnaco expects to achieve these cost
      savings principally through streamlining operational, financial and
      administrative functions, eliminating public company expenses, including
      the cost of directors, outside auditors and listing and filing expenses,
      eliminating certain lease commitments and eliminating certain insurance
      costs. Warnaco notes that achieving these earnings and cost savings is
      subject to certain risks as discussed in the sections 'Risk Factors' and
      'Cautionary Statement Concerning Forward-Looking Statements' on pages 13
      and 36.
 
      Warnaco believes it can grow revenues for the Calvin Klein khakis, jeans
      and jean-related sportswear businesses, including the knit and woven tops
      business, at a rate of 15% per year after 1998, as well as improve the
      results of operations of Designer Holdings. This estimated growth rate is
      based upon an estimated $400 million gross revenue base for fiscal year
      1998. Warnaco notes that achieving this growth is subject to certain risks
      as discussed in the sections 'Risk Factors' and 'Cautionary Statement
      Concerning Forward-Looking Statements' on pages 13 and 36.
 
Information and Factors Considered by the Warnaco Board
 
     The Warnaco Board considered the Exchange and the Merger together as one
transaction, with the expectation that one would not be consummated without the
other and that Warnaco would become the holder of all the outstanding Designer
Holdings shares. Nevertheless, the Warnaco Board also considered the
implications of consummating only the Exchange, and its
 
                                       20
 

<PAGE>

<PAGE>
approval of the transactions manifested its willingness to consummate the
Exchange whether or not the Merger was consummated. The Warnaco Board made its
determination after careful consideration of, and based on, a number of factors
including those described below, which are the material factors considered by
the Warnaco Board:
 
          (a) all the reasons described above under ' -- Warnaco's Reasons for
     the Merger';
 
          (b) the financial presentation of Lazard Freres described under
     ' -- Background of the Merger' and ' -- Opinion of Lazard Freres & Co.
     LLC', including the opinion of Lazard Freres orally delivered and
     subsequently confirmed in writing, to the effect that the Exchange Ratio in
     connection with the Exchange and the Merger, taken as a whole, was fair to
     Warnaco and its stockholders from a financial point of view (a copy of the
     written opinion dated September 25, 1997 of Lazard Freres, setting forth
     the assumptions, limitations and qualifications set forth in such opinion,
     is attached as Annex C hereto); see ' -- Opinion of Lazard Freres & Co.
     LLC';
 
          (c) information concerning the business, assets, capital structure,
     financial performance and condition and prospects of Designer Holdings;
 
          (d) current and historical market prices and trading information with
     respect to each company's common stock;
 
          (e) the strategic fit between Warnaco and Designer Holdings, including
     Warnaco's pre-existing relationship with Calvin Klein, Inc. ('CKI'), the
     opportunity for significant cost savings as described under ' -- Warnaco's
     Reasons for the Merger' and the potential for growth in Designer Holdings'
     business;
 
          (f) the fact that New Rio was willing to enter into the Exchange
     Agreement and that as a result thereof, (i) assuming the closing of the
     Exchange prior to the record date for the Designer Holdings Meeting,
     Warnaco would own 51.3% of the outstanding Designer Holdings Common Stock
     for purposes of voting to approve the Merger and (ii) in the event the
     closing of the Exchange did not occur prior to the record date for the
     Designer Holdings Meeting, New Rio had agreed to vote all its shares of
     Designer Holdings Common Stock in favor of the Merger;
 
          (g) the possibility that the Merger would not be consummated following
     the closing of the Exchange and that, in such event Warnaco would have a
     controlling interest in a publicly traded company; in this regard, the
     Warnaco Board considered that Warnaco would own 51.3% of the Designer
     Holdings shares, as well as control a majority of the Designer Holdings
     Board, Warnaco would be able to consolidate Designer Holdings' results of
     operations with its own for accounting purposes, and that the terms of the
     Merger Agreement removed nearly all conditions to closing the Merger
     following the closing of the Exchange;
 
          (h) the likelihood of obtaining required regulatory approvals and the
     timing of obtaining such approvals; and
 
          (i) the interests of Designer Holdings' officers and directors,
     including Mr. Simon, in the Merger and the Exchange, including the fact
     that the Exchange would permit Mr. Simon to terminate his employment
     agreement with Designer Holdings, the costs associated with such a
     termination and the desirability of retaining Mr. Simon as president and
     chief executive officer of Designer Holdings following the Exchange and the
     Merger; see 'Interests of Certain Persons in the Merger'.
 
     In view of the wide variety of factors considered in connection with its
evaluation of the Merger and the complexity of these matters, the Warnaco Board
did not find it practicable to and did not attempt to quantify, rank or
otherwise assign relative weights to these factors. In addition, the Warnaco
Board did not undertake to make any specific determination as to whether any
particular factor (or any aspect of any particular factor) was favorable or
unfavorable to the Warnaco Board's ultimate determination, but rather conducted
an overall analysis of the factors described above, including through
discussions with and questioning of Warnaco's management and advisors.
Furthermore, in considering the factors described above, individual members of
the Warnaco Board may have given different weight to different factors. The
Warnaco Board considered all these fac-
 
                                       21

<PAGE>
tors as a whole, and believed that the combination of these factors supported
its decision to approve the Merger and the Exchange. Discussions among the
Warnaco Board members evidenced that overall, factors (a), (c) and (e) supported
the Board's determination from a strategic perspective, while factors (b) and
(d) supported the Board's fairness determination. Factors (f) and (h) were
viewed as positive factors in ensuring that Warnaco would be able to consummate
the transaction while factors (g) and (i) were considered fully by the Warnaco
Board without clearly supporting or otherwise affecting its determination. In
addition, in evaluating the information included in factor (c), the Warnaco
Board considered recent news articles relating to a downward revision by
Designer Holdings in its earnings estimates for the remainder of 1997, as well
as increased competition in the jeans market. The Warnaco Board determined,
after consultation with management of Warnaco, that such information had been
considered and reflected in the determination of the Exchange Ratio.
 
Recommendation of the Warnaco Board
 
     The Warnaco Board recommends that the stockholders of Warnaco vote 'FOR'
approval of the issuance of shares of Warnaco Common Stock in connection with
the Merger and the Exchange and upon the conversion of any of the Convertible
Debentures and the TOPrS.
 
INFORMATION AND FACTORS CONSIDERED BY THE DESIGNER HOLDINGS BOARD;
RECOMMENDATION OF THE DESIGNER HOLDINGS BOARD
 
     In reaching its decision to recommend the approval and adoption of the
Merger Agreement and the Merger, the Designer Holdings Board carefully
considered a number of factors, including those described below, which are the
material factors considered by the Designer Holdings Board:
 
          (a) the financial presentation of Merrill Lynch at the Designer
     Holdings Board meeting on September 24, 1997 and described under
     ' -- Background of the Merger' and ' -- Opinion of Merrill Lynch',
     including the oral opinion of Merrill Lynch (subsequently confirmed in
     writing on September 25) to the effect that, as of such date and based upon
     and subject to the factors set forth in such opinion, the Exchange Ratio in
     the Merger is fair from a financial point of view to the Designer Holdings
     stockholders (other than Warnaco, New Rio and their respective affiliates)
     (a copy of the written opinion of Merrill Lynch is attached as Annex D
     hereto);
 
          (b) Designer Holdings' business, assets, management, financial
     performance and condition, strategic objectives, prospects and competitive
     position, including the views of Designer Holdings' management, and current
     industry, economic and market conditions;
 
          (c) a review of potential alternatives to the proposed transaction,
     including a public auction of Designer Holdings, a transaction with another
     strategic buyer and continuation as an independent company, and whether it
     was likely that Designer Holdings could successfully pursue such
     alternatives on terms and conditions at least as favorable to the Designer
     Holdings stockholders as Warnaco's proposal;
 
          (d) the fact that New Rio, Designer Holdings' largest stockholder,
     which owned approximately 51.3% of Designer Holdings' outstanding shares,
     supported Warnaco's proposal (which support continued to be a condition to
     Warnaco's proposal) and was willing to sell its shares for the same
     consideration as the public stockholders of Designer Holdings, as well as
     accept the risk that the sale of its shares to Warnaco would be fully
     taxable in the event the Merger was not consummated;
 
          (e) the risk that the Merger would not be consummated despite the
     elimination of substantially all conditions to closing the Merger following
     the closing of the Exchange, in which event, given that Warnaco would own
     51.3% of the outstanding Designer Holdings shares, there could be no
     assurance that Designer Holdings' public stockholders would have an
     alternative means of selling their shares at a premium;
 
          (f) the fact that the value of the Exchange Ratio, based on the
     closing price of Warnaco shares on September 16, 1997, represented a
     premium of approximately 17.3% over the clos-
 
                                       22
 

<PAGE>

<PAGE>
     ing price of Designer Holdings Common Stock on September 16, 1997, which
     was the last trading day prior to the announcement of Warnaco's proposal;
     and the fact that the value of the Exchange Ratio was less than Designer
     Holdings' initial public offering price of $18 per share in May 1996 and
     that Designer Holdings Common Stock had traded at prices both substantially
     higher, but also substantially lower than such value since that time
     (although it had not traded higher since December 12, 1996);
 
          (g) the fact that the value, as of the Effective Time of the Merger,
     of the shares of Warnaco Common Stock to be received in the Merger for each
     Designer Holdings share will vary as a result of any changes in the value
     of Warnaco Common Stock and that any such change in value as a result of
     any increase or decrease in the value of the shares of Warnaco Common Stock
     will not be limited by any 'collar' arrangement;
 
          (h) the strategic fit between Warnaco and Designer Holdings, including
     the opportunity for cost savings, including lowering distribution costs,
     eliminating public company expenses, streamlining operational, financial
     and administrative functions and eliminating lease commitments, as well as
     enhanced brand presentation and the potential for appreciation in the value
     of Warnaco's shares as a result of the Merger and the ability of Designer
     Holdings' stockholders to participate in any growth in the combined
     company; in this connection, the Board considered the challenges of
     combining the businesses of Warnaco and Designer Holdings and the attendant
     risk of not achieving the expected cost savings, enhanced brand
     presentation or improved earnings; see ' -- Cautionary Statement Concerning
     Forward-Looking Statements';
 
          (i) the fact that the Merger Agreement was structured to allow the
     Designer Holdings Board, but only prior to the closing of the Exchange, to
     consider additional unsolicited third party offers to acquire Designer
     Holdings, and that during such period the Merger Agreement would permit
     Designer Holdings to terminate the Merger Agreement if the Designer
     Holdings Board were to determine in its good faith judgment that a proposed
     alternative transaction were more favorable to Designer Holdings'
     stockholders than the Merger, and, as a result thereof, determined in good
     faith, based on the advice of outside counsel, that it was obligated by its
     fiduciary obligations under applicable law to terminate the Merger
     Agreement; in this connection, the Designer Holdings Board noted that New
     Rio would not have any right to terminate the Exchange Agreement if the
     Board terminated the Merger Agreement;
 
          (j) the terms and conditions of the Merger Agreement and the Exchange
     Agreement, including the parties' respective representations, warranties,
     covenants, agreements and conditions to their respective obligations,
     including the limited conditions to Warnaco's obligation to consummate the
     Merger following the closing of the Exchange;
 
          (k) the business, management, assets and financial performance and
     condition of Warnaco;
 
          (l) the interests of Designer Holdings' officers and directors,
     including Mr. Simon, in the Merger and the Exchange, including the fact
     that the Exchange would permit Mr. Simon to terminate his existing
     employment agreement with Designer Holdings; see 'Interests of Certain
     Persons in the Merger';
 
          (m) the likelihood of obtaining required regulatory approvals and the
     timing of obtaining such approvals;
 
          (n) the ability to consummate the Merger as a tax-free reorganization
     for Federal income tax purposes; see ' -- Certain U.S. Federal Income Tax
     Consequences';
 
          (o) the fact that the Merger Agreement contained several provisions
     intended to ensure that the employees of Designer Holdings received
     adequate benefits; see 'Interests of Certain Persons in the Merger' and
     'The Merger Agreement -- Certain Covenants -- Certain Employee Benefit
     Matters';
 
          (p) the fact that, during the period from closing of the Exchange
     through the closing of the Merger, three current directors of Designer
     Holdings would continue as directors of Designer Holdings, and that,
     pursuant to the Merger Agreement, the vote of a majority of such continuing
     directors would be required in connection with certain actions relating to
     the Merger Agreement; and
 
                                       23
 

<PAGE>

<PAGE>
          (q) the fact that certain employees of Designer Holdings would receive
     bonuses aggregrating $7 million (of which $3.5 million would be paid by
     each of Designer Holdings and New Rio); see 'Interests of Certain Persons
     in the Merger'.
 
     The directors concluded that, given New Rio's majority ownership position,
the existence of the Exchange Agreement would make it unlikely that a third
party would propose a business combination with Designer Holdings prior to or
subsequent to the closing of the Exchange. The directors also considered the
fact that Designer Holdings had not sought business combination proposals from
other parties nor received any offers from other parties prior to or subsequent
to the public announcement of the proposed transaction. In this regard, the
Designer Holdings Board took into account that fact that New Rio was willing to
enter into the Exchange Agreement and supported the terms of the Merger
Agreement. See 'The Exchange Agreement'.
 
     Prior to its approval of the Merger Agreement and the Merger, the Designer
Holdings Board was apprised of and considered all aspects of each director's
relationship with Designer Holdings and New Rio. For a discussion of these
relationships, see 'Interests of Certain Persons in the Merger'. In light of the
fact that each of the directors had such a relationship, the Board did not
establish an independent committee to negotiate the terms of the Merger.
 
     The foregoing discussion of the information and factors considered by the
Designer Holdings Board is not intended to be exhaustive, but is believed to
include all material factors considered by the directors. In view of the variety
of factors considered in connection with their evaluation of the Merger, the
Designer Holdings Board did not find it practicable to, and did not, quantify or
otherwise attempt to assign relative weight to the specific factors considered
in reaching its determination. The Designer Holdings Board relied on the
experience and expertise of Merrill Lynch for quantitative analysis of the
Exchange Ratio from a financial point of view.
 
     The Designer Holdings Board did not undertake to make any specific
determination as to whether any particular factor (or any aspect of any
particular factor) was favorable or unfavorable to the Designer Holdings Board's
ultimate determination, but rather conducted an overall analysis of the factors
described above, including through discussions with Designer Holdings'
management and legal, financial and accounting advisors. In considering the
factors described above, individual directors may have given different weights
to different factors. Discussions among the Designer Holdings Board members
evidenced that factors (b), (j), (k) and (l) were considered as part of the
general mix of available information without being clearly favorable or
unfavorable, factors (e) and (g) were considered an uncertainty relating to the
transaction, and the other reasons and factors described above were generally
considered favorable. However, discussions among the Designer Holdings Board
members also evidenced that in considering factors (g), (i) and (j), the
directors considered unfavorable the potential for a decrease in the value of
the shares of Warnaco Common Stock to be received by Designer Holdings
stockholders in the Merger based on any decrease in the market price of Warnaco
Common Stock and the absence of any arrangement to limit the extent of any such
decrease; the limitations contained in the Merger and Exchange Agreements on
Designer Holdings' and New Rio's ability to solicit alternative third party
transaction proposals; and the fact that New Rio would not have any right to
terminate the Exchange Agreement in the event that the Designer Holdings Board
had terminated the Merger Agreement after being presented with an alternative
transaction more favorable than the Merger. Notwithstanding the foregoing, the
Designer Holdings Board considered all of these factors as a whole, and on
balance considered the factors to be favorable to and supportive of its
determination to approve the Merger Agreement and the Merger.
 
     Based on the factors outlined above, the Designer Holdings Board
unanimously determined that the Merger Agreement and Exchange Agreement and the
transactions contemplated thereby are fair to and in the best interests of the
Designer Holdings stockholders (other than Warnaco, New Rio and their respective
affiliates), and approved the Merger Agreement, the Exchange Agreement and the
Merger.

IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION. THE ENGAGEMENT OF
LAZARD FRERES AND ITS OPINION ARE FOR THE BENEFIT OF THE WARNACO BOARD, AND ITS

TAKEN AS A WHOLE, FROM A FINANCIAL POINT OF VIEW TO WARNACO AND ITS STOCKHOLDERS
AND DOES NOT ADDRESS ANY OTHER ASPECTS OF THE EXCHANGE AND THE MERGER. THE
OPINION IS NOT INTENDED TO, AND DOES NOT CONSTITUTE, A RECOMMENDATION TO ANY
HOLDER OF WARNACO COMMON STOCK AS TO WHETHER SUCH HOLDER SHOULD VOTE FOR THE
ISSUANCE OF SHARES OF WARNACO COMMON STOCK IN CONNECTION WITH THE MERGER.
HOLDERS OF WARNACO COMMON STOCK ARE URGED TO READ THE OPINION OF LAZARD FRERES
IN ITS ENTIRETY.
 
     In connection with rendering its written opinion dated September 25, 1997
to the Warnaco Board, Lazard Freres: (1) reviewed the financial terms and
conditions of drafts of the Exchange Agreement and the Merger Agreement, each
dated September 24, 1997; (2) analyzed certain historical business and financial
information relating to Warnaco and Designer Holdings; (3) reviewed the various
financial forecasts and other data provided to Lazard Freres by Warnaco relating
to its businesses and the benefits projected by Warnaco to be realized in
connection with the Merger; (4) reviewed the various financial forecasts and
other data provided to Lazard Freres by Warnaco relating to the businesses of
Designer Holdings and by Designer Holdings relating to its businesses (which
included financial forecasts for the current and next fiscal years only, having
been advised that Designer Holdings had not prepared projections beyond such
fiscal years); (5) held discussions with members of senior management of each of

     Lazard Freres relied upon the accuracy and completeness of the information
described in the preceding paragraph and did not assume any responsibility for
any independent verification of such information or any independent valuation or
appraisal of any of the assets or liabilities of Warnaco or Designer Holdings.
With respect to financial forecasts, including the benefits projected to be
realized following the Exchange and the Merger, Lazard Freres assumed that they
were reasonably prepared on bases reflecting the best currently available
estimates and judgments of management of Warnaco and Designer Holdings as to the
future financial performance of Warnaco and Designer Holdings, respectively. In
that regard, Lazard Freres noted in its opinion that such financial forecasts
assumed that the License Agreement dated as of August 4, 1994, as amended,
between CKI and a subsidiary of Designer Holdings would remain in full force and
effect for the period covered by such forecasts. Lazard Freres assumed no
responsibility for and expressed no view as to such forecasts or the assumptions
on which they were based.
 
     In rendering its opinion, Lazard Freres assumed that, in all respects
material to its analysis, the Exchange and the Merger would be consummated on
the terms described in the Exchange Agreement and the Merger Agreement,
respectively, without any waiver of any material terms or conditions by Warnaco,
and that obtaining the necessary regulatory approvals for the Exchange and the
Merger would not have an adverse effect on Warnaco or Designer Holdings and that
the projected benefits of the Exchange and the Merger would be realized
substantially in accordance with such projections. Lazard Freres also assumed
that the definitive Exchange Agreement and the Merger Agreement would not differ
in any material respect from the drafts furnished to it.
 
     Lazard Freres was engaged by Warnaco as of September 19, 1997 for purposes
of delivering its opinion to the Warnaco Board, and, as a result, Lazard Freres
did not participate in the negotiation of the Exchange Ratio or of any of the
other terms of the Exchange or the Merger.
 
     The following is a summary of the material financial and comparative
analyses performed by Lazard Freres in connection with providing its oral
opinion to the Warnaco Board and reviewed with the Warnaco Board at its meeting
on September 24, 1997.
 
     Comparable Publicly Traded Companies Analysis. Lazard Freres reviewed and
compared certain actual and estimated financial, operating and stock market
information of companies in lines of businesses believed to be generally
comparable to those of Designer Holdings. Such apparel companies included Jones
Apparel Group, Inc., Liz Claiborne, Inc., Nautica Enterprises, Inc., Tommy
Hilfiger Corporation and V.F. Corporation (collectively, the 'Selected Designer
Holdings Comparables'), as well as Chic By H.I.S., Inc., Donna Karan
International Inc., Guess ?, Inc. and Mossimo, Inc. (collectively with the
Selected Designer Holdings Comparables, the 'Designer Holdings Comparables').
The analysis indicated that the enterprise values (determined as the market
value of common equity plus preferred equity at liquidation value plus net debt)
of the Selected Designer Holdings Comparables as a multiple of 1997 estimated
net sales ranged from 1.2x to 2.2x (with a median for the Designer Holdings
Comparables of 1.4x), as a multiple of 1998 estimated net sales ranged from 1.1x
to 1.8x (with a median for the Designer Holdings Comparables of 1.3x), as a
multiple of 1997 estimated earnings before interest, taxes, depreciation and
amortization ('EBITDA') ranged from 8.4x to 14.8x (with a median for the
Designer Holdings Comparables of 9.8x), as a multiple of 1998 estimated EBITDA
ranged from 7.8x to 12.3x (with a median for the Designer Holdings Comparables
of 8.8x), as a multiple of 1997 estimated earnings before interest and taxes
('EBIT') ranged from 10.6x to 15.8x (with a median for the Designer Holdings
Comparables of 11.5x), as a multiple of 1998 estimated EBIT ranged from 9.4x to
13.1x (with a median for the Designer Holdings Comparables of 10.2x), and also
indicated that the equity value per share as a multiple of 1997 estimated
earnings per share ('EPS') ranged from 18.0x to 26.6x (with a median for the
Designer Holdings Comparables of 19.6x), and as a multiple of 1998 estimated EPS
ranged from 15.1x to 22.1x (with a median for the Designer Holdings Comparables
of 17.3x).
 
     Based upon the foregoing data and projected EPS for Designer Holdings
provided to Lazard Freres, the implied enterprise value of Designer Holdings was
estimated to range from $346 million to $385 million, and the implied per share
equity valuation of Designer Holdings Common Stock (equal to the implied
enterprise value minus net debt in an amount equal to the difference
 
                                       26

<PAGE>
between the face amount of the 6% Convertible Trust Originated Preferred
Securities issued by Designer Finance Trust and guaranteed by Designer Holdings
of $120.0 million and $61.3 million in cash, divided by 32.2 million shares of
Designer Holdings Common Stock outstanding) was estimated to range from $9.00 to
$10.20. This analysis further indicated that the ranges of implied estimated
enterprise values of Designer Holdings set forth in the preceding sentence
implied multiples of 1997 and 1998 estimated net sales of Designer Holdings
ranging from 0.8x to 0.9x and 0.9x to 1.0x, respectively, multiples of 1997 and
1998 estimated EBITDA of Designer Holdings ranging from 9.5x to 10.5x and 7.8x
to 8.7x, respectively, and multiples of 1997 and 1998 estimated EBIT of Designer
Holdings ranging from 11.0x to 12.3x and 8.7x to 9.6x, respectively, and that
the ranges of the implied equity value per share of Designer Holdings implied
multiples of 1997 and 1998 estimated EPS of Designer Holdings ranging from 19.7x
to 22.3x and 15.0x to 17.0x, respectively.
 
     Selected Precedent Transactions Analysis. Lazard Freres reviewed selected
financial, operating and stock market information relating to selected
acquisition transactions in the apparel industry since July 1992. Such
transactions included Maidenform Worldwide Inc./NCC Industries, Inc.,
Phillips-Van Heusen Corporation/Crystal Brands, Inc.-Apparel Group, Fruit of the
Loom, Inc. (Farley, Inc.)/Salem Sportswear Corporation and Investor Group
(Marciano Family)/Guess ?, Inc. (collectively, the 'Selected Apparel Comparable
Transactions'), as well as Investor Group (Management and The Jordan Co.)/Tee
Jays Holding Corp., Calvin Klein Jeanswear Company (New Rio)/Jeans division
(Calvin Klein Inc.), Fruit of the Loom, Inc. (Farley, Inc.)/The Gitano Group,
Inc., Warnaco Inc./Underwear business (Calvin Klein Inc.), V.F. Corporation/H.H.
Cutler Co., Jones Apparel Group, Inc./Evan-Picone Inc. (Crystal Brands, Inc.),
Chemical Venture Partners/Apollo/Buster Brown Apparel Inc. (Gerber Products
Company) and Sporloisirs S.A./Lacoste Alligator S.A. (Crystal Brands, Inc.)
(collectively with the Selected Apparel Comparable Transactions, the 'Apparel
Comparable Transactions'). The analysis indicated that the transaction values in
the Selected Apparel Comparable Transactions as a multiple of latest twelve
months ('LTM') net sales ranged from 0.5x to 1.5x (with a median for the Apparel
Comparable Transactions of 0.8x), as a multiple of LTM EBITDA ranged from 5.7x
to 16.3x (with a median for the Apparel Comparable Transactions of 9.1x), as a
multiple of LTM EBIT ranged from 6.3x to 10.4x (with a median for the Apparel
Comparable Transactions of 10.3x), and as a multiple of LTM EPS ranged from 8.7x
to 13.6x (with a median for the Apparel Comparable Transactions of 13.7x).
 
     Based upon the foregoing data and LTM EBITDA for Designer Holdings provided
to Lazard Freres, the implied enterprise value of Designer Holdings was
estimated to range from $372 million to $465 million, and the implied per share
equity valuation of the Designer Holdings Common Stock (equal to the implied
enterprise value minus net debt in an amount equal to the difference between the
face amount of the 6% Convertible Trust Originated Preferred Securities issued
by Designer Finance Trust and guaranteed by Designer Holdings of $120.0 million
and $61.3 million in cash, divided by 32.2 million shares of Designer Holdings
Common Stock outstanding) was estimated to range from $9.80 to $12.69. This
analysis further indicated that the ranges of implied estimated enterprise
values of Designer Holdings set forth in the preceding sentence implied
multiples of LTM net sales of Designer Holdings ranging from 0.8x to 1.0x,
multiples of LTM EBITDA of Designer Holdings ranging from 6.0x to 7.5x,
multiples of LTM EBIT of Designer Holdings ranging from 6.6x to 8.2x, and
multiples of LTM EPS of Designer Holdings ranging from 11.2x to 14.5x.
 
     Discounted Cash Flow Analysis. Based upon forecasts provided by the
respective management of Designer Holdings and Warnaco, Lazard Freres estimated
the net present value of the future free cash flows of Designer Holdings, both
including and excluding certain cost savings estimated by Warnaco management to
be realized following consummation of the Exchange and the Merger. For this
analysis, Lazard Freres used discount rates ranging from 12.5% to 13.5% and
multiples of estimated EBITDA in year 2002 ranging from 8.0x to 10.0x. This
analysis indicated an implied per share equity valuation of Designer Holdings
Common Stock (based upon net debt in an amount equal to the difference between
the face amount of the 6% Convertible Trust Originated Preferred
 
                                       27
 

<PAGE>

<PAGE>
Securities issued by Designer Finance Trust and guaranteed by Designer Holdings,
of $120.0 million and $61.3 million in cash, and 32.2 million shares of Designer
Holdings Common Stock outstanding) ranging from $17.92 to $22.37 including
estimated cost savings, and from $13.98 to $17.56 excluding estimated cost
savings.
 
     Lazard Freres also performed a sensitivity analysis of such implied per
share equity valuations of Designer Holdings Common Stock using discount rates
ranging from 12.5% to 13.5%, a multiple of estimated EBITDA in year 2002 of
9.0x, and compound annual growth rates of revenues for Designer Holdings in
years 1999 through 2002 ranging from 6.0% to 12.0%. This analysis indicated an
implied per share equity valuation of Designer Holdings Common Stock (based upon
net debt in an amount equal to the difference between the face amount of the 6%
Convertible Trust Originated Preferred Securities issued by Designer Finance
Trust and guaranteed by Designer Holdings of $120.0 million and $61.3 million in
cash, and 32.2 million shares of Designer Holdings Common Stock outstanding)
ranging from $16.92 to $22.08 including estimated cost savings, and from $12.76
to $17.57 excluding estimated cost savings.
 
     Contribution Analysis. Lazard Freres also considered the contribution of
each of Warnaco and Designer Holdings to the revenues, EBITDA, EBIT and net
income of the pro forma combined company using Warnaco management's estimates
for 1997 and 1998, both including and excluding certain cost savings estimated
by Warnaco management to be realized in 1998 following consummation of the
Exchange and the Merger. Designer Holdings' contribution of revenues, EBITDA,
EBIT and net income were estimated to be 21.9%, 20.1%, 20.2% and 21.6%,
respectively, in 1998, including estimated cost savings. In addition, Designer
Holdings' contribution of revenues, EBITDA, EBIT and net income were estimated
to be 25.1%, 13.7%, 12.9% and 13.1%, respectively, in 1997, excluding cost
savings, and 21.9%, 15.0%, 14.6% and 14.8%, respectively, in 1998, excluding
estimated cost savings. Based upon fully-diluted shares outstanding of 54.2
million for Warnaco Common Stock and 32.2 million for Designer Holdings Common
Stock and the Exchange Ratio, holders of Designer Holdings Common Stock
(including New Rio) would own approximately 16.1% of the combined company's
total equity value (on a fully diluted basis) upon consummation of the Exchange
and the Merger.
 
     Pro Forma Merger Analysis. Lazard Freres considered the effect that the
Exchange and the Merger, taken as a whole, could have on the EPS of the combined
company, both including and excluding certain cost savings estimated by Warnaco
management to be realized following consummation thereof, compared with the
projected EPS of Warnaco on a stand-alone basis. After giving effect to the
estimates and assumptions described above, the analysis indicated that,
including estimated cost savings, the Exchange and the Merger, taken as a whole,
would be accretive to the projected stand-alone EPS in 1998 through 2000. The
analysis also showed that if Warnaco were not to achieve any of the estimated
cost savings, the Exchange and the Merger, taken as a whole, would be modestly
dilutive to the projected stand-alone EPS of Warnaco in 1998 and accretive to
the EPS of Warnaco in 1999 and 2000.
 
     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or the summary set forth above without considering the
analyses as a whole, could create an incomplete or misleading view of the
process underlying the opinion of Lazard Freres. No company or transaction used
in the above analyses as a comparison is identical to Warnaco or Designer
Holdings or the transactions contemplated by the Exchange Agreement and the
Merger Agreement. The analyses were prepared solely for the purpose of Lazard
Freres providing its opinion to the Warnaco Board in connection with its
consideration of the Exchange and the Merger and do not purport to be appraisals
or necessarily reflect the prices at which businesses or securities actually may
be sold, which may be significantly more or less favorable than as set forth in
these analyses. Similarly, any estimate of values or forecast of future results
contained in the analyses is not necessarily indicative of actual values or
actual future results, which may be significantly more or less favorable than
suggested by such analyses.

     In performing its analyses, Lazard Freres made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters. Because such analyses are inherently subject to uncertainty,
being based upon numerous factors or events beyond the control of the parties or
their respective advisors, none of Warnaco, Lazard Freres, or any other person
assumes responsibility if future results or actual values are materially
different from those forecasts or estimates contained in the analyses.
 
     Lazard Freres is an internationally recognized investment banking firm and
is continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, secondary
distributions of listed and unlisted securities, private placements, leveraged
buyouts, and valuations for estate, corporate and other purposes. Lazard Freres
was selected to act as financial advisor to the Warnaco Board because of its
expertise and its reputation in investment banking and mergers and acquisitions.
 
     In connection with Lazard Freres' delivery of the opinion summarized above,
Warnaco has paid Lazard Freres a fee of $600,000. Warnaco also has agreed to
reimburse Lazard Freres for its reasonable out-of-pocket expenses (including
reasonable fees and expenses of its legal counsel) and will indemnify Lazard
Freres and certain related parties against certain liabilities, including
certain liabilities arising under the federal securities laws.
 
     In the ordinary course of its business, Lazard Freres and its affiliates
may actively trade in the securities of Warnaco and Designer Holdings for their
own account and for the account of their customers and, accordingly, may at any
time hold a long or short position in such securities.
 
OPINION OF MERRILL LYNCH
 
     On September 17, 1997, Designer Holdings retained Merrill Lynch to render
its opinion as to whether or not the proposed consideration to be received by
the holders of Designer Holdings Common Stock in the Merger is fair to such
shareholders from a financial point of view. On September 25, 1997, Merrill
Lynch rendered to the Designer Holdings Board its written opinion (the 'Merrill
Lynch Opinion') that, as of such date and based upon and subject to the factors
and assumptions set forth therein, the Exchange Ratio in the Merger was fair
from a financial point of view to the holders of Designer Holdings Common Stock
(other than Warnaco, New Rio and their affiliates). Such written opinion
confirmed its earlier oral opinion provided to the Designer Holdings Board on
September 24, 1997.
 
     THE FULL TEXT OF THE MERRILL LYNCH WRITTEN OPINION, WHICH SETS FORTH THE
ASSUMPTIONS MADE, MATTERS CONSIDERED, AND QUALIFICATIONS AND LIMITATIONS ON THE
REVIEW UNDERTAKEN BY MERRILL LYNCH, IS ATTACHED AS ANNEX D HERETO AND IS
INCORPORATED HEREIN BY REFERENCE. STOCKHOLDERS OF DESIGNER HOLDINGS ARE URGED TO
READ SUCH OPINION IN ITS ENTIRETY. THE MERRILL LYNCH OPINION WAS PROVIDED TO THE
DESIGNER HOLDINGS BOARD FOR ITS USE AND BENEFIT AND IS DIRECTED ONLY TO THE
FAIRNESS FROM A FINANCIAL POINT OF VIEW OF THE EXCHANGE RATIO IN THE MERGER TO
THE HOLDERS OF DESIGNER HOLDINGS COMMON STOCK (OTHER THAN WARNACO, NEW RIO AND
THEIR AFFILIATES), DOES NOT ADDRESS THE MERITS OF THE UNDERLYING DECISION BY
DESIGNER HOLDINGS TO ENGAGE IN THE MERGER AND DOES NOT CONSTITUTE A
RECOMMENDATION TO DESIGNER HOLDINGS' STOCKHOLDERS AS TO HOW SUCH STOCKHOLDERS
SHOULD VOTE ON THE PROPOSED MERGER. THE SUMMARY OF THE MERRILL LYNCH OPINION SET
FORTH IN THIS JOINT PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO THE FULL TEXT OF SUCH OPINION.
 
     In arriving at its opinion, Merrill Lynch, among other things: (i) reviewed
Designer Holdings' Initial Public Offering Prospectus, dated May 9, 1996, the
Prospectus for the offering of the TOPrS, dated November 1, 1996, Designer
Holdings' Annual Report, Form 10-K and related financial information for the
fiscal year ended December 31, 1996 and Designer Holdings' Forms 10-Q
 
                                       29

and the related unaudited financial information for the quarterly periods ending
March 31, 1997 and June 30, 1997; (ii) reviewed Warnaco's Prospectus for shares
of Warnaco Common Stock, dated September 19, 1995, Warnaco's Annual Reports,
Forms 10-K and related financial information for the three fiscal years ended
January 4, 1997 and Warnaco's Forms 10-Q and the related unaudited financial
information for the quarterly periods ending April 5, 1997 and July 5, 1997;
(iii) reviewed certain information, including financial forecasts, relating to
the business, earnings, cash flow, assets, liabilities and prospects of Designer
Holdings and Warnaco, furnished to or discussed with Merrill Lynch by Designer
Holdings and Warnaco management, respectively; (iv) conducted discussions with
members of senior management of Designer Holdings and Warnaco concerning their
respective businesses and prospects, before and after giving effect to the
Merger; (v) reviewed the historical market prices and valuation multiples for
the Designer Holdings Common Stock and the Warnaco Common Stock and compared
them with those of certain publicly traded companies that Merrill Lynch deemed
reasonably similar to Designer Holdings and Warnaco, respectively; (vi) reviewed
certain financial information of Designer Holdings and Warnaco and compared them
with those of certain publicly traded companies that Merrill Lynch deemed to be
relevant; (vii) compared the proposed financial terms of the Merger with the
financial terms of certain other transactions in the apparel industry
specifically, of which Merrill Lynch noted there were a limited number which it
deemed to be relevant, and in other industries generally; (viii) reviewed the
potential pro forma impact of the Merger; (ix) reviewed drafts of the Merger
Agreement and the Exchange Agreement dated September 25, 1997 in the forms
proposed to be entered into; and (x) reviewed such other financial studies and
analyses and took into account such other matters as Merrill Lynch deemed
necessary, including its assessment of general economic, market and monetary
conditions.
 
     In preparing its opinion, Merrill Lynch assumed and relied on the accuracy
and completeness of all information supplied or otherwise made available to
Merrill Lynch, discussed with or reviewed by or for Merrill Lynch, or publicly
available, and Merrill Lynch did not assume any responsibility for independently
verifying such information and did not undertake an independent evaluation or
appraisal of any of the assets or liabilities of Designer Holdings or Warnaco.
In addition, Merrill Lynch did not assume any obligation to conduct, nor did
Merrill Lynch conduct, any physical inspection of the properties or facilities
of Designer Holdings or Warnaco. With respect to the financial forecast
information furnished to or discussed with Merrill Lynch by Designer Holdings or
Warnaco, Merrill Lynch assumed that they were reasonably prepared and reflect
the best currently available estimates and judgments of Designer Holdings' or
Warnaco's management as to the expected future financial performance of Designer
Holdings or Warnaco, as the case may be. Merrill Lynch further assumed that the
Merger will qualify as a tax-free reorganization for U.S. federal income tax
purposes. Merrill Lynch also assumed that the final form of the Merger Agreement
and the Exchange Agreement would be in the forms of the last drafts reviewed by
Merrill Lynch.
 
     The Merrill Lynch Opinion is necessarily based upon market, economic and
other conditions as they existed and could be evaluated on, and on the
information made available to Merrill Lynch as of, the date of such opinion.
Merrill Lynch assumed that in the course of obtaining the necessary regulatory
or other consents or approvals (contractual or otherwise) for the Merger, no
restrictions, including any divestiture requirements or amendments or
modifications, will be imposed that will have a material adverse effect on the
contemplated benefits of the Merger. Merrill Lynch was not authorized by
Designer Holdings or the Designer Holdings Board to solicit, nor did it solicit,
third-party indications of interest for the acquisition of all or any part of
Designer Holdings. Merrill Lynch did not participate in any discussions or
negotiations among representatives of Designer Holdings and Warnaco, including
Warnaco's financial and legal advisors. In addition, Merrill Lynch was not asked
to consider, and the Merrill Lynch Opinion does not in any manner address, the
price at which shares of Warnaco will trade following the announcement or
consummation of the Merger.

     The following is a summary of the material financial and comparative
analyses performed by Merrill Lynch in connection with the preparation of the
Merrill Lynch Opinion and reviewed by it with the Designer Holdings Board.
 
     Relative Discounted Cash Flow Analysis. Using projections for Designer
Holdings prepared by its management for the fiscal years ending December 31,
1997 and 1998 and extrapolations by Merrill Lynch based on discussions with
management for the fiscal years ending December 31, 1999 through December 31,
2004 (the 'Designer Holdings Projections'), Merrill Lynch calculated ranges of
implied per share equity values for Designer Holdings based upon the sum of the
discounted net present value of Designer Holdings' seven year stream of
projected unlevered after-tax Free Cash Flow (defined as earnings before
interest and taxes, excluding extraordinary and non-recurring charges ('EBIT'),
tax-effected, plus depreciation and amortization, minus capital expenditures,
minus (plus) increases (decreases) in working capital) and the discounted net
present value of a terminal value based on a (1) range of multiples of its
projected calendar year 2004 earnings, before interest, taxes, depreciation and
amortization, excluding extraordinary and non-recurring charges ('EBITDA') and
(2) range of perpetuity growth rates of 2004 Free Cash Flow. In performing this
analysis, Merrill Lynch utilized discount rates reflecting a weighted average
cost of capital ranging from 12.3% to 14.3% and terminal value multiples of
calendar year 2004 EBITDA ranging from 6.5x to 8.5x and perpetuity growth rates
of calendar year 2004 Free Cash Flow ranging from 4% to 6%. This analysis
resulted in implied per share equity value ranges and implied total equity value
ranges for Designer Holdings from $8.95 to $12.61 and from $287.8 million to
$405.4 million, respectively, for the terminal EBITDA multiple method and value
ranges from $5.75 to $9.46 and from $184.8 million to $304.3 million,
respectively, for the perpetuity growth method. Merrill Lynch also performed
this analysis utilizing discount rates reflecting a weighted average cost of
capital ranging from 11.3% to 15.3%. This analysis resulted in implied per share
equity value ranges and implied total equity value ranges for Designer Holdings
from $8.42 to $13.42 and from $270.7 million to $431.6 million, respectively,
for the terminal EBITDA multiple method and value ranges from $5.08 to $11.56
and from $163.2 million to $371.7 million, respectively, for the perpetuity
growth method.
 
     Using projections for Warnaco prepared by its management for the fiscal
years ending December 31, 1997 through 2002 and extrapolations by Merrill Lynch
based on such projections for the fiscal years ending December 31, 2003 and 2004
(the 'Warnaco Projections'), Merrill Lynch calculated ranges of implied per
share equity values for Warnaco based upon the sum of the discounted net present
value of Warnaco's seven year stream of projected unlevered after-tax Free Cash
Flow and the discounted net present value of a terminal value based on a range
of multiples of its projected calendar year 2004 EBITDA and a range of
perpetuity growth rates of 2004 Free Cash Flow. In performing this analysis,
Merrill Lynch utilized discount rates ranging from 10.3% to 12.3% and terminal
value multiples of calendar 2004 EBITDA ranging from 7.5x to 9.5x and perpetuity
growth rates of calendar year 2004 Free Cash Flow ranging from 4% to 6%. This
analysis resulted in implied per share equity value ranges and implied total
equity value ranges from $38.21 to $53.36 and from $1,991.1 million to $2,780.9
million, respectively, for the terminal EBITDA multiple method and value ranges
for Warnaco from $27.52 to $55.43 and from $1,434.4 million to $2,888.4 million,
respectively, for the perpetuity growth method. Merrill Lynch also performed
this analysis utilizing discount rates reflecting a weighted average cost of
capital ranging from 9.3% to 13.3%. This analysis resulted in implied per share
equity value ranges and implied total equity value ranges for Warnaco from
$35.82 to $56.95 and from $1,866.6 million to $2,967.8 million, respectively,
for the terminal EBITDA multiple method and value ranges from $23.56 to $74.94
and from $1,227.9 million to $3,905.1 million, respectively, for the perpetuity
growth method.
 
     Merrill Lynch calculated implied exchange ratio ranges by comparing the
Designer Holdings implied per share equity value ranges calculated using the
Designer Holdings Projections with the Warnaco implied per share equity values
calculated using the Warnaco Projections. This analysis resulted in implied
exchange ratio ranges of 0.233 to 0.238, having an implied value per share
ranging from $8.00 to $8.17 (based on the closing price per share of Warnaco as
of September 23,
 
                                       31

1997 of $34 3/8), for the terminal EBITDA method and ranges of 0.171 to 0.209,
having an implied value per share ranging from $5.87 to $7.18 (based on the same
closing price per share), for the perpetuity growth method.
 
     Merrill Lynch also calculated implied exchange ratios by comparing implied
per share equity value ranges calculated using the assumptions that the Designer
Holdings EBIT for the seven years ending December 31, 2004 is 5% higher in
absolute value than that assumed in the Designer Holdings Projections, while the
Warnaco EBIT for the same period is 5% lower than that assumed in the Warnaco
Projections ('Case One'). Merrill Lynch also calculated implied exchange ratios
by comparing implied per share equity value ranges calculated using the
assumptions that the Designer Holdings EBIT for the seven years ending December
31, 2004 is 10% higher in absolute value than that assumed in the Designer
Holdings Projections, while the Warnaco EBIT for the same period is 10% lower
than that assumed in the Warnaco Projections ('Case Two'). In performing the
analyses of Case One and Case Two, Merrill Lynch utilized discount rates ranging
from 12.3% to 14.3% for Designer Holdings and from 10.3% to 12.3% for Warnaco,
and utilized terminal value multiples of calendar year 2004 EBITDA and
perpetuity growth rates of calendar year 2004 Free Cash Flow described above for
Designer Holdings and Warnaco. The analysis of Case One resulted in implied
exchange ratios of 0.249 to 0.254 for the terminal EBITDA method and ranges of
0.188 to 0.231 for the perpetuity growth method, while the analysis of Case Two
resulted in implied exchange ratios of 0.265 to 0.270 for the terminal EBITDA
method and ranges of 0.204 to 0.254 for the perpetuity growth method.
 
     Contribution Analysis. Merrill Lynch analyzed the respective contributions
of each of Designer Holdings and Warnaco to the estimated sales, EBITDA, EBIT
and net income of the resulting company on a pro forma basis, before taking into
account any of the possible benefits that may be realized following the Merger,
for the years 1995 through 2000, and compared such contributions to the relative
ownership positions of the existing Designer Holdings stockholders and Warnaco
stockholders after the Merger. The analysis indicated that stockholders of
Designer Holdings (including New Rio) would own 16.0% of the common shares of
the combined company on a pro forma, fully diluted basis (based on the closing
price per share of Warnaco as of September 23, 1997 of $34 3/8 provided that for
purposes of calculating dilution, the TOPrS were not treated as converted
because they are not in the money). Using historical, publicly available
information, the Designer Holdings Projections and the Warnaco Projections, the
analysis indicated that Designer Holdings would contribute to historical and/or
estimated (i) revenues, 33.5% in 1995, 31.1% in 1996, 27.3% in 1997, 22.4% in
1998, 22.0% in 1999, 21.6% in 2000, 20.8% in 2001, 20.4% in 2002, 20.4% in 2003
and 20.0% in 2004, (ii) EBITDA, 20.5% in 1995, 25.8% in 1996, 15.7% in 1997,
12.6% in 1998, 15.1% in 1999, 16.5% in 2000, 16.5% in 2001, 15.9% in 2002, 15.4%
in 2003 and 15.0% in 2004, (iii) EBIT, 23.3% in 1995, 27.6% in 1996, 15.8% in
1997, 12.5% in 1998, 15.1% in 1999, 16.5% in 2000, 16.3% in 2001, 15.6% in 2002,
15.0% in 2003 and 14.5% in 2004 and (iv) net income, 18.2% in 1995, 25.4% in
1996, 16.2% in 1997, 12.6% in 1998, 15.6% in 1999, 17.4% in 2000, 17.2% in 2001,
16.3% in 2002, 15.5% in 2003 and 14.7% in 2004.
 
     Historical Stock Price Analysis. Merrill Lynch reviewed the historical
ratios implied by the daily closing prices of Designer Holdings Common Stock to
those of Warnaco Common Stock (the 'Historical Trading Ratios') for the 12
month, 6 month, 30 day and 7 day periods ending September 15, 1997, and compared
such Historical Trading Ratios to the Exchange Ratio of 0.324. This analysis
showed that the average Historical Trading Ratios for the 12 month, 6 month, 30
day and 7 day periods ending September 15, 1997 were 0.477, 0.280, 0.230 and
0.284, respectively, and that the maximum and minimum Historical Trading Ratios
for the 12 month, 6 month, 30 day and 7 day periods ending September 15, 1997
were 1.184 and 0.184, 0.363 and 0.184, 0.316 and 0.189 and 0.316 and 0.246,
respectively.
 
     Public Comparable Companies Analysis. Merrill Lynch performed public
comparable companies analyses pursuant to which it compared certain publicly
available financial and operating data, projections of future financial
performance (reflecting First Call Corporation estimates as of September 19,
1997 and publicly reported Merrill Lynch research reports) and market statistics
(based on
 
                                       32

<PAGE>
closing stock prices on September 19, 1997) of eight companies with that for
Designer Holdings (with respect to whom projections of future financial
performance reflect published Merrill Lynch research projections for 1997 and
1998 ('Street Case Projections') and market statistics are based on Designer
Holdings closing stock prices on September 15, 1997, the day before public
disclosure of Warnaco's offer). These companies include Guess ?, Inc., Jones
Apparel Group, Inc., Liz Claiborne, Inc., Nautica Enterprises, Inc., Polo Ralph
Lauren Corporation, Tommy Hilfiger Corporation, V.F. Corporation and The Warnaco
Group, Inc. Merrill Lynch compared share prices as, among other things,
multiples of estimates of 1997 EPS and estimates of 1998 EPS and compared market
capitalization (defined as market value plus preferred equity at liquidation
value plus short-term debt plus long-term debt plus minority interest minus cash
and marketable securities) as, among other things, multiples of LTM EBITDA, 1997
estimated EBITDA, 1998 estimated EBITDA, LTM EBIT, 1997 estimated EBIT, 1998
estimated EBIT and LTM sales. With respect to such group, Merrill Lynch's
analysis indicated (i) mean and median market value as a multiple of 1997
estimated EPS of 20.6x and 19.6x, 1998 estimated EPS of 18.0x and 17.8x and LTM
cash flow of 20.2x and 17.1x and (ii) mean and median market capitalization as a
multiple of LTM EBITDA of 12.8x and 11.6x, 1997 estimated EBITDA of 10.9x and
10.3x, 1998 estimated EBITDA of 9.4x and 8.9x, LTM EBIT of 14.7x and 13.6x, 1997
estimated EBIT of 12.4x and 11.6x, 1998 estimated EBIT of 10.6x and 10.1x and
LTM sales of 2.05x and 1.98x. With respect to Designer Holdings, Merrill Lynch's
analysis indicated (i) market value as a multiple of 1997 estimated EPS of
19.5x, 1998 estimated EPS of 18.2x and LTM cash flow of 7.1x and (ii) market
capitalization as a multiple of LTM EBITDA of 5.2x, 1997 estimated EBITDA of
9.4x, 1998 estimated EBITDA of 9.0x, LTM EBIT of 5.7x, 1997 estimated EBIT of
11.0x, 1998 estimated EBIT of 10.5x and LTM sales of .66x.
 
     No company utilized in the public comparable companies analysis was
identical to Designer Holdings. Accordingly, an analysis of the results of such
a comparison is not purely mathematical; rather it involves complex
considerations and judgments concerning differences in historical and projected
financial and operating characteristics of the comparable companies and other
factors that could affect the public trading value of the comparable companies
or company to which they are being compared.
 
     Comparable Acquisitions Analysis. Merrill Lynch reviewed certain publicly
available information regarding 28 selected apparel industry acquisitions
announced since February 1988 (the 'Acquisition Comparables') and for each
transaction calculated (i) the offer value (defined as the value of the offer
for 100% of the equity, on a fully diluted basis, of the target) for the
relevant company as a multiple of LTM net income, LTM cash flow (defined as net
income plus depreciation and amortization plus deferred taxes) and LTM book
value and (ii) transaction value (defined as offer value plus total debt minus
cash and cash equivalents) as a multiple of LTM EBITDA, LTM EBIT and LTM
revenues. Such analysis indicated that (i) the offer value as a multiple of LTM
net income ranged from 6.1x to 29.9x, with a mean of 15.0x and a median of
13.6x, as a multiple of LTM cash flow ranged from 5.2x to 19.9x, with a mean of
10.5x and a median of 9.4x and as a multiple of LTM book value ranged from 1.30x
to 4.93x, with a mean of 2.76x and a median of 2.33x and (ii) the transaction
value as a multiple of LTM EBITDA ranged from 4.4x to 13.2x, with a mean of 7.6x
and a median of 7.4x, as a multiple of LTM EBIT ranged from 4.8x to 17.0x, with
a mean of 9.6x and a median of 8.9x and as a multiple of LTM revenues ranged
from 0.16x to 1.97x, with a mean of 0.86x and a median of 0.76x.
 
     Merrill Lynch calculated aggregate and per share equity values for Designer
Holdings by applying Designer Holdings' LTM results, Designer Holdings
Projections and Street Case Projections, to the median multiples derived from
its analysis of the Acquisition Comparables described above. Merrill Lynch
calculated per share imputed equity values of Designer Holdings (assuming 32.2
million shares outstanding and net debt of $42.3 million) ranging from $7.01 to
$14.10 (based on transaction values as a multiple of sales, EBITDA and EBIT for
LTM and 1997 and 1998 Designer Holdings Projections) and ranging from $6.51 to
$14.10 (based on transaction values as a multiple of sales, EBITDA and EBIT for
LTM and 1997 and 1998 Street Case Projections).

     There were a limited number of transactions in the apparel industry which
Merrill Lynch deemed to be relevant. No company utilized in the comparable
apparel industry acquisitions analysis was identical to Designer Holdings or
Warnaco. Accordingly, an analysis of the results of this comparison is not
purely mathematical; rather it involves complex considerations and judgments
concerning differences in historical and projected financial and operating
characteristics of the comparable acquired companies and other factors that
could affect the offer value of such companies and Designer Holdings.
 
     Pro Forma Analysis. Merrill Lynch analyzed certain pro forma effects
resulting from the Merger including the effect of the consummation of the Merger
on the EPS of Warnaco following the Merger and the impact on Designer Holdings
and Warnaco shareholders. In conducting its analysis, Merrill Lynch relied upon
certain of the Designer Holdings Projections and of the Warnaco Projections. The
results of this analysis were that, assuming the realization of Warnaco
management's expected cost savings, the accretive (dilutive) effects of the
Merger to Designer Holdings' stockholders were $0.19 or 38.2% in 1998, $0.08 or
10.9% in 1999, ($0.00) or (0.5%) in 2000 and $0.01 or 1.3% in 2001 and to
Warnaco stockholders were $0.05 or 2.5% in 1998, $0.13 or 5.5% in 1999 and $0.21
or 7.6% in 2000. The analysis also showed that without giving effect to any cost
savings, the accretive (dilutive) effects of the Merger to Designer Holdings'
stockholders were $0.13 or 25.8% in 1998, $0.01 or 1.9% in 1999, ($0.07) or
(7.7%) in 2000 and ($0.06) or (5.4%) in 2001 and to Warnaco stockholders was
($0.14) or (6.7%) in 1998, ($0.07) or (3.0%) in 1999 and ($0.01) or (0.2%) in
2000. The results of the pro forma analysis are not necessarily indicative of
future operating results or financial position of the combined companies.
 
     Stock Trading History. Merrill Lynch reviewed and analyzed the history of
the trading prices for Designer Holdings Common Stock and Warnaco Common Stock,
both separately and in relation to each other. In addition, Merrill Lynch
reviewed and analyzed the relationship between movements of the prices of
Designer Holdings Common Stock and Warnaco Common Stock and movements in the
Standard & Poor's industrial average of 400 stocks and composite indices based
upon prices of selected companies in the apparel industry. These analyses
indicated that except for a brief period following Designer Holdings' initial
public offering in May 1996, trading prices for Designer Holdings Common Stock
significantly underperformed the Standard & Poor's industrial average and the
composite index; and that over the last three years the trading price of Warnaco
Common Stock substantially tracked the performance of the Standard & Poor's
industrial average and the composite index, except that during 1996, the
composite index substantially overperformed both the Standard & Poor's
industrial average and Warnaco Common Stock. As of August 28, 1997, the date
upon which the underperformance of Designer Holdings Common Stock reached its
maximum, Designer Holdings Common Stock had underperformed relative to the
Standard & Poor's industrial average and the composite index by 82.2% and 74.3%,
respectively. See 'Historical Stock Price Analysis' above for a discussion of
the historical ratios implied by the daily closing prices of Designer Holdings
Common Stock to those of Warnaco Common Stock for the 12 month, 6 month, 30 day
and 7 day periods ending September 15, 1997. In addition, Merrill Lynch
calculated the premium represented by the implied offer price of $11.14 per
Designer Holdings Share (based on the September 23, 1997 closing price of
Warnaco Common Stock of $34 3/8) over the average trading prices of Designer
Holdings Common Stock for the one day, 7 days, 30 days and 6 months ending
September 15, 1997. This analysis showed that the offer price premium was 36.0%,
52.0%, 69.5% and 20.7%, respectively.
 
     The preparation of a fairness opinion is a complex analytical process
involving various determinations as to the most appropriate and relevant methods
of financial analysis and the application of those methods to the particular
circumstances and, therefore, such an opinion is not readily susceptible to
partial analysis or summary description. In arriving at its opinion, Merrill
Lynch did not attribute any particular weight to any analysis or factor
considered by it. Accordingly, Merrill Lynch believes that its analyses must be
considered as a whole and that selecting portions of its analyses, without
considering all of its analyses, would create an incomplete view of the process
underlying the Merrill Lynch Opinion.

     In performing its analyses, numerous assumptions were made with respect to
industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of Merrill
Lynch, Designer Holdings, or Warnaco. Any estimates contained in the analyses
performed by Merrill Lynch are not necessarily indicative of actual values or
future results, which may be significantly more or less favorable than suggested
by such analyses. Additionally, estimates of the value of businesses or
securities do not purport to be appraisals or to reflect the prices at which
such businesses or securities might actually be sold. Accordingly, such analyses
and estimates are inherently subject to substantial uncertainty. In addition, as
described above, the Merrill Lynch Opinion and Merrill Lynch's presentation to
the Designer Holdings Board were among several factors taken into consideration
by the Designer Holdings Board in making its determination to approve the Merger
Agreement. Consequently, the Merrill Lynch analyses described herein should not
be viewed as determinative of the decision of the Designer Holdings Board or
Designer Holdings' management with respect to the fairness of the Exchange
Ratio.
 
     Merrill Lynch Financial Advisory Fee. Pursuant to a letter agreement dated
September 17, 1997 between Designer Holdings and Merrill Lynch, Designer
Holdings agreed to pay Merrill Lynch (i) a fee of $750,000 payable in cash on
the date Merrill Lynch delivered the Merrill Lynch Opinion and (ii) in the event
that an offer is received by Designer Holdings from another party to acquire
Designer Holdings or all or substantially all of its assets or business by
merger or otherwise or the terms of the Merger are materially revised and the
Designer Holdings Board or a committee thereof considers such other offer or
such revised terms, additional compensation in an amount to be agreed upon by
Designer Holdings and Merrill Lynch for such services as it may perform at the
request of the Designer Holdings Board in advising the Designer Holdings Board
or a committee thereof with respect to such other offer or such revised terms.
Designer Holdings also agreed to reimburse Merrill Lynch for its reasonable
out-of-pocket expenses, including reasonable fees and disbursements of its legal
counsel. Additionally, Designer Holdings agreed to indemnify Merrill Lynch and
certain related persons for certain liabilities related to or arising out of its
engagement, including liabilities under federal securities laws.
 
     Designer Holdings retained Merrill Lynch based upon Merrill Lynch's
experience and expertise. Merrill Lynch is an internationally recognized
investment banking and advisory firm. Merrill Lynch, as part of its investment
banking business, is continuously engaged in the valuation of businesses and
securities in connection with mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and
unlisted securities, private placements and valuations for corporate and other
purposes. Merrill Lynch has in the past provided financial advisory and
financing services to Designer Holdings, including having acted as lead
underwriter in connection with its initial public offering on May 9, 1996 and
with its offering of the TOPrS on November 1, 1996, and to Warnaco, including
having acted as lead underwriter in connection with its offering of Warnaco
Common Stock on September 19, 1995, and may continue to do so and has received,
and may receive, fees for the rendering of such services. In addition, in the
ordinary course of Merrill Lynch's business, Merrill Lynch may actively trade
Designer Holdings Common Stock and other securities of Designer Holdings, as
well as Warnaco Common Stock for its own account and for the accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities.
 
EXPECTED COST SAVINGS FROM THE MERGER
 
     Warnaco believes that the combination of Warnaco and Designer Holdings will
generate approximately $14 million of estimated net cost savings in 1998, which
number represents approximately $19 million of savings in selling, general and
administrative expense of Designer Holdings, net of $5 million in amortization
of goodwill. These estimates were prepared by the management of Warnaco, after
consultation with the management of Designer Holdings. The $19 million of
selling, general and administrative expense savings consists of (a)
approximately $13.4 million from the streamlining of operational, financial and
administrative functions, including sourcing, production,
 
                                       35
 

<PAGE>

<PAGE>
distribution, management information systems, finance, legal and administrative
functions, as well as in the outlet stores, (b) approximately $2.9 million from
the elimination of public company expenses, including legal, audit, investor
relations, filing and board of directors expenses, (c) approximately $1.7
million from the elimination of certain lease commitments and (d) approximately
$1 million from the elimination of certain insurance costs. Warnaco notes that
achieving these cost savings is subject to certain risks as discussed in the
sections 'Risk Factors' and 'Cautionary Statement Concerning Forward-Looking
Statements' on pages 13 and 36. In addition, the failure to achieve these cost
savings in the amounts and at the times anticipated could result in increased
expenses, and thereby reduced earnings of Warnaco.
 
     Since consummating the Exchange, Warnaco has taken steps that will result
in the achievement of approximately $5 million of payroll reductions as well as
approximately $1.7 million in eliminated lease commitments. Upon consummation of
the Merger, Warnaco expects to realize another $3.9 million from the elimination
of Designer Holdings' public company expenses and the reduction of insurance
costs.
 
CERTAIN FINANCIAL PROJECTIONS
 
     In connection with its evaluation of the Merger, Warnaco, and in connection
with the analyses described above under ' -- Opinion of Lazard Freres & Co.
LLC', Lazard Freres, were provided with certain non-public financial projections
for Designer Holdings that had been prepared by Designer Holdings' management
(the 'Projections'), the material portions of which are set forth below:
 
<TABLE>

                                                                           1997        1998

                                                                            (IN THOUSANDS)
 
<S>                                                                      <C>         <C>
Net revenues..........................................................   $488,809    $437,000
Gross profit..........................................................    182,768     179,940
Income before non-recurring items, interest and income taxes..........     39,154      42,550
Net income............................................................     19,156      20,857
</TABLE>
 
     In addition to the Projections, other projections prepared by Designer
Holdings management were subsequently provided by Designer Holdings to Warnaco,
Lazard Freres and Merrill Lynch which showed, for 1997 and 1998, respectively,
net revenues of $487.8 million and $412.0 million, gross profit of $181.3
million and $166.9 million, income before non-recurring items, interest and
income taxes of $37.7 million and $31.7 million, and net income of $19.0 million
and $15.9 million. Merrill Lynch relied upon these latter projections in
connection with the analyses and opinion described above under ' -- Opinion of
Merrill Lynch'. Neither Designer Holdings nor Warnaco does, as a matter of
course, publicly disclose projections as to future revenues, earnings or other
financial information. Stockholders of Designer Holdings should note that
neither set of projections is included in this Joint Proxy Statement/Prospectus
to induce any stockholder to vote for the Merger. In addition, neither set of
projections reflects any changes in the operation of Designer Holdings'
business, including those described above under ' -- Expected Cost Savings from
the Merger', anticipated to be implemented by Warnaco, and as a result Warnaco
did not rely on either set of projections in formulating its assessment of
Designer Holdings' future financial results. Designer Holdings' projections were
based upon a variety of assumptions, including those related to the achievement
of strategic goals, objectives and targets over the applicable periods. Such
assumptions involve judgments with respect to, among other things, future
economic, competitive and regulatory conditions, foreign currency exchange
rates, financial market conditions and future business decisions, all of which
are difficult or impossible to predict accurately and many of which are beyond
the control of Designer Holdings or, after the Merger, Warnaco. Designer
Holdings' projections were not prepared with a view to public disclosure, use in
this Joint Proxy Statement/Prospectus or compliance with published guidelines of
the SEC, nor were they prepared in accordance with the guidelines established by
the American Institute of Certified Public Accountants for preparation and
presentation of financial projections. In light of the uncertainties inherent
 
                                       36
 

<PAGE>

<PAGE>
in any projected data, stockholders are cautioned not to place undue reliance on
the projections. See 'Risk Factors' and ' -- Cautionary Statement Concerning
Forward-Looking Statements.'
 
CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS
 
     This document contains certain forward-looking statements which are subject
to risks and uncertainties. Forward-looking statements include information
concerning future results of operations, cost savings and synergies of Warnaco
and Designer Holdings after the Effective Time, and concerning the ability of
Warnaco to elevate the performance level and grow the business of Designer
Holdings after the Effective Time, set forth under 'Questions and Answers About
The Merger', 'Summary', 'Risk Factors', ' -- Background of the Merger',
' -- Warnaco's Reasons for the Merger; Recommendation of the Warnaco Board',
' -- Information and Factors Considered by the Designer Holdings Board;
Recommendation of the Designer Holdings Board', ' -- Opinion of Lazard Freres &
Co. LLC', ' -- Opinion of Merrill Lynch', ' -- Expected Cost Savings from the
Merger' and ' -- Certain Financial Projections' and those preceded by, followed
by or that otherwise include the words 'believes', 'expects', 'anticipates',
'intends', 'estimates' or similar expressions. For those statements, we claim
the protection of the safe harbor for forward-looking statements contained in
the Private Securities Litigation Reform Act of 1995. You should understand that
the following important factors, in addition to those discussed under 'Risk
Factors' and elsewhere in this document and in the documents which we
incorporate by reference, could affect the future results of Warnaco and
Designer Holdings, and of Designer Holdings after the Effective Time, and could
cause those results to differ materially from those expressed in our
forward-looking statements: materially adverse changes in economic conditions
generally or in the markets served by our companies; changes in consumer
spending habits; the impact of inflation; competition from other makers and
distributors of jeans, sportswear, underwear, accessories and other apparel;
pressure by department stores and other customers to provide increased services
and to absorb additional costs; risks relating to Warnaco's ability to combine
the business and operations of Designer Holdings with a substantially larger
major corporation and the challenges inherent in diverting Warnaco's management
focus and resources from other strategic opportunities and from operational
matters for an extended period of time; Warnaco's and Designer Holdings'
relationships with licensors, including CKI, sublicensees and suppliers;
Warnaco's and Designer Holdings' dependence on certain licenses and the names
associated therewith pursuant to which they have the right to produce,
distribute, advertise and sell, and to authorize others to produce, distribute,
advertise and sell, garments under certain labels; Designer Holdings' and
Warnaco's relationships with and dependence upon certain manufacturers that
produce its merchandise; and the impact of any future regulations affecting
imported goods and foreign suppliers.
 
ACCOUNTING TREATMENT
 
     For accounting and financial reporting purposes, the Merger is intended to
be treated as a purchase by Warnaco under generally accepted accounting
principles. Under the purchase method of accounting, the assets and liabilities
of the corporation not surviving a merger are, as of the effective date of the
merger, recorded at their respective fair values and added to those of the
surviving corporation. Financial statements of the surviving corporation issued
after consummation of the merger reflect such values and are not restated
retroactively to reflect the historical financial position or results of
operations of the corporation not surviving.
 
     The unaudited pro forma combined financial statements contained in this
Joint Proxy Statement/Prospectus have been prepared using the purchase method to
account for the Merger. See 'Summary -- Selected Unaudited Pro Forma Combined
Financial Information' and 'Unaudited Pro Forma Combined Financial Statements'.
 
CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES
 
     In connection with the filing of this Joint Proxy Statement/Prospectus,
Simpson Thacher has delivered to Warnaco an opinion, and Skadden Arps has
delivered to Designer Holdings an opinion, regarding the material federal income
tax consequences of the Merger to stockholders of
 
                                       37
 

<PAGE>

<PAGE>
Designer Holdings and to Warnaco, WAC and Designer Holdings. The opinions are
filed as exhibits to the registration statement of which this Joint Proxy
Statement/Prospectus forms a part, are dated the date of this Joint Proxy
Statement/Prospectus and are based upon certain customary assumptions and
representations, including representations contained in certificates (and
confirmations thereof) of Warnaco, Designer Holdings and others, all as
described in greater detail in such opinions, and all of which must continue to
be true and accurate in all material respects as of the Effective Time or such
opinions will be withdrawn. It is a condition to the consummation of the Merger
that neither opinion be withdrawn or modified in any material respect as of the
Effective Time. No ruling has been sought from the Internal Revenue Service as
to the federal income tax consequences of the Merger, and the opinions of
counsel will not bind the Internal Revenue Service or any court.
 
     The opinions state that the material federal income tax consequences of the
Merger to stockholders of Designer Holdings and to Warnaco, WAC and Designer
Holdings are as follows: (i) the Merger will be treated for federal income tax
purposes as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the 'Code'); (ii) Warnaco, WAC and
Designer Holdings will each be a party to the reorganization within the meaning
of Section 368(b) of the Code; (iii) no gain or loss will be recognized by
Warnaco, WAC or Designer Holdings as a result of the Merger; (iv) no gain or
loss will be recognized by the stockholders of Designer Holdings upon the
exchange of their shares of Designer Holdings Common Stock solely for shares of
Warnaco Common Stock pursuant to the Merger, except with respect to cash, if
any, received in lieu of fractional shares of Warnaco Common Stock; (v) the
aggregate tax basis of the shares of Warnaco Common Stock received solely in
exchange for shares of Designer Holdings Common Stock pursuant to the Merger
will be the same as the aggregate tax basis of the shares of Designer Holdings
Common Stock exchanged therefor, decreased by the tax basis allocated to any
fractional share interest exchanged for cash; (vi) the holding period for shares
of Warnaco Common Stock received in exchange for shares of Designer Holdings
Common Stock pursuant to the Merger will include the holding period of the
shares of Designer Holdings Common Stock exchanged therefor, provided such
shares of Designer Holdings Common Stock were held as capital assets by the
stockholder at the Effective Time; and (vii) a stockholder of Designer Holdings
who receives cash in lieu of a fractional share of Warnaco Common Stock will
recognize a gain or loss equal to the difference, if any, between such
stockholder's tax basis in such fractional share and the amount of cash
received. Such gain or loss will constitute capital gain or loss if such
stockholder's Designer Holdings Common Stock is held as a capital asset at the
Effective Time. Under recently enacted legislation, capital gains of individuals
derived in respect of capital assets are eligible for reduced rates of taxation
depending on the holding period of such capital assets.
 
     Designer Holdings stockholders will be required to retain records and file
with their U.S. federal income tax returns a statement setting forth certain
facts relating to the Merger.
 
     Backup Withholding. Certain noncorporate holders of Designer Holdings
Common Stock may be subject to backup withholding at a rate of 31% on cash
payments received in lieu of a fractional share interest in Warnaco Common
Stock. Backup withholding will not apply, however, to a stockholder who (i)
furnishes a correct taxpayer identification number and certifies that he or she
is not subject to backup withholding on the substitute Form W-9 included in the
letter of transmittal to be delivered to Designer Holdings stockholders
following consummation of the Merger, (ii) provides a certificate of foreign
status on Form W-8 or (iii) is otherwise exempt from backup withholding. Backup
withholding is not an additional tax. Any amounts withheld under the backup
withholding rules from a cash payment in lieu of a fractional share interest in
Warnaco Common Stock will be refunded or credited against the holder's U.S.
federal income tax liability, if any, provided that the required information is
furnished to the Internal Revenue Service.
 
     The foregoing discussion is based on currently existing provisions of the
Code, applicable Treasury Regulations thereunder, current administrative rulings
and court decisions, all of which are subject to change and any such change
could affect the continuing validity of the discussion. The discussion does not
purport to address all of the tax consequences applicable to all categories
 
                                       38
 

<PAGE>

<PAGE>
of stockholders. In particular, the discussion does not addresss the special tax
rules that may apply to holders of Designer Holdings Common Stock subject to
special treatment under the Code, such as foreign holders or holders whose
shares were acquired pursuant to the exercise of an employee stock option or
otherwise as compensation. In addition, there may be relevant state, local or
other tax consequences, none of which are discussed herein. Designer Holdings
stockholders are urged to consult their tax advisors to determine the specific
tax consequences to them of the Merger.
 
REGULATORY MATTERS
 
     Under the HSR Act and the rules promulgated thereunder by the Federal Trade
Commission (the 'FTC'), the Merger may not be consummated until notifications
have been given and certain information has been furnished to the FTC and the
Antitrust Division of the United States Department of Justice (the 'Antitrust
Division') and specified waiting period requirements have been satisfied. On
October 3, 1997, Warnaco and Designer Holdings received notice from the FTC and
the Antitrust Division of the early termination of the waiting period under the
HSR Act. Nevertheless, the FTC and the Antitrust Division retain the authority
to challenge the Merger on antitrust grounds after the Merger is completed. In
addition, each state in which Warnaco or Designer Holdings operates may also
review the Merger under state antitrust law. It is possible that some of these
authorities may impose conditions for granting approval of the Merger.
 
NO APPRAISAL RIGHTS
 
     Holders of Designer Holdings Common Stock are not entitled to dissenters'
appraisal rights under the Delaware General Corporation Law (the 'DGCL') in
connection with the Merger because the Designer Holdings Common Stock was listed
on the NYSE on the record date for the Designer Holdings Meeting and the shares
of Warnaco Common Stock that such holders will be entitled to receive in the
Merger will be listed on the NYSE at the Effective Time. Holders of Warnaco
Common Stock are not entitled to dissenters' appraisal rights under the DGCL in
connection with the Merger because Warnaco is not a constituent corporation in
the Merger.
 
FEDERAL SECURITIES LAWS CONSEQUENCES; STOCK TRANSFER RESTRICTION
 
     This Joint Proxy Statement/Prospectus does not cover any resales of the
Warnaco Common Stock to be received by the stockholders of Designer Holdings
upon consummation of the Merger, and no person is authorized to make any use of
this Joint Proxy Statement/Prospectus in connection with any such resale.
 
     All shares of Warnaco Common Stock received by Designer Holdings
stockholders in the Merger will be freely transferable, except that shares of
Warnaco Common Stock received by persons who are deemed to be 'affiliates' of
Designer Holdings under the Securities Act of 1933, as amended (the 'Securities
Act'), at the time of the Designer Holdings Meeting may be resold by them only
in transactions permitted by Rule 145 or as otherwise permitted under the
Securities Act. Persons who may be deemed to be affiliates of Designer Holdings
for such purposes generally include individuals or entities that control, are
controlled by, or are under common control with, Designer Holdings and may
include certain officers, directors and principal stockholders of Designer
Holdings. The Merger Agreement requires Designer Holdings to provide Warnaco
with a letter identifying such persons and to cause each of such affiliates to
execute a written agreement to the effect that such persons will not offer or
sell or otherwise dispose of any of the shares of Warnaco Common Stock issued to
such persons in the Merger in violation of the Securities Act or the rules and
regulations promulgated by the Securities and Exchange Commission ('SEC')
thereunder.
 
     Warnaco has agreed in the Exchange Agreement to use its reasonable best
efforts to file and have declared effective as soon as practicable following the
Effective Time a registration statement under the Securities Act for resales of
the shares of Warnaco Common Stock issued in the Exchange and not subject to a
Lock-Up Letter. Initially, 80% of the Warnaco shares issued in the Exchange will
be covered by such registration statement. See 'The Exchange
Agreement -- Registration Rights'.
 
                                       39
 

<PAGE>

<PAGE>
     Under the Exchange Agreement, the Sellers have agreed, among other things,
not to offer, sell, transfer or otherwise dispose of any shares of Warnaco
Common Stock until the earlier of (i) such time at or after the Effective Time
that is no earlier than the time when holders of Designer Holdings Common Stock
can sell the shares of Warnaco Common Stock issued pursuant to the Merger and
(ii) the termination of the Merger Agreement in accordance with its terms. The
Sellers have also agreed not to transfer any shares of Warnaco Common Stock
until such shares are registered under the Securities Act (unless an exemption
from such registration is available), and not to sell, transfer or otherwise
dispose of more than 80% of such shares in the aggregate for a period of one
year following the Effective Time. However, a Seller may enter into a
transaction to dispose of more than 80% of such shares if (i) there has been an
unforeseen change in circumstances and the Seller obtains the written opinion of
Skadden Arps that such transaction will not prevent the Exchange and the Merger
from together qualifying as a tax-free reorganization under the provisions of
Section 368 of the Code, (ii) in the case of an individual Seller, such Seller
has died, or (iii) in the case of a Seller classified as a partnership, such
Seller has distributed all of its assets subject to a plan of complete
liquidation.
 
CERTAIN STOCKHOLDER LITIGATION
 
     Shortly after the announcement of a proposed transaction between Designer
Holdings and Warnaco, three stockholders of Designer Holdings, Jacob J. Spinner,
Yaakov Glatter and Sherry Berman, as custodian for Jordan Berman, filed lawsuits
in the Delaware Court of Chancery challenging the transaction. The named
plaintiff in each of the actions purports to maintain each individual action as
a class action on behalf of Designer Holdings stockholders. On October 30, 1997
the Court of Chancery signed an order which consolidated the three actions. Now
captioned as In re Designer Holdings Ltd. Shareholders Litigation, Consolidated
Civil Action 15942, the consolidated complaint alleges that the directors of
Designer Holdings breached their fiduciary duties to Designer Holdings'
stockholders in approving the transaction. The complaint further alleges that
the directors have a conflict of interest based on the price at which they
acquired the Designer Holdings shares they own and the price at which Designer
Holdings shares were sold to the public in May 1996 relative to the transaction
price. The plaintiffs also claim that Warnaco aided and abetted the directors of
Designer Holdings in breaching their fiduciary duties. The plaintiffs seek
injunctive relief to prohibit Designer Holdings from completing the Merger, or
in the alternative, monetary damages of an unspecified amount.
 
     On November 13, 1997, the parties to this litigation reached an agreement
in principle to settle this litigation on the following terms, subject to court
approval:
 
          1. the defendants permitted the plaintiffs' attorneys to review drafts
     of this Joint Proxy Statement/Prospectus prior to mailing and have revised
     the disclosure herein in response to their comments;
 
          2. the defendants agreed that they would reduce the termination fee
     payable to Warnaco in certain circumstances from $12.5 million to $6.5
     million; and
 
          3. CEP II, which beneficially owns approximately 2.6 million Warnaco
     shares as a result of the Exchange, has agreed that during the 14-day
     period following the Release Date (as defined in the Exchange Agreement),
     but in no event extending past December 31, 1997, it will not sell,
     transfer or otherwise dispose of any Warnaco shares, notwithstanding the
     existence of an effective registration statement for the resale of any such
     shares, unless the closing price for Warnaco shares on the NYSE Composite
     Transactions Tape on any day within such 14-day period was more than 15%
     above or below such closing price on the trading day immediately preceding
     the Effective Time of the Merger.
 
     Upon final approval of the settlement by the court, plaintiffs' counsel
will petition the court for an award of attorney's fees and expenses, which will
be paid by Designer Holdings. Plaintiffs' counsel has agreed to submit a request
for, and the defendants have agreed not to oppose, a request for court approval
of not more than $350,000 in attorney's fees and expenses.

(1) Designer Holdings closed its initial public offering of Designer Holdings
    Common Stock on May 15, 1996.
 
                            ------------------------
     On September 16, 1997, the last full trading day prior to the public
announcement of the proposed Merger, the closing prices on the NYSE Composite
Transaction Tape were $33 15/16 per share of Warnaco Common Stock and $9 3/8 per
share of Designer Holdings Common Stock. On November 13, 1997, the most recent
practicable date prior to the printing of this Joint Proxy Statement/Prospectus,
the closing prices on the NYSE Composite Transaction Tape were $26 15/16 per
share of Warnaco Common Stock and $8 9/16 per share of Designer Holdings Common
Stock. Stockholders are urged to obtain current market quotations prior to
making any decision with respect to the Merger.
 
     We expect no changes in Warnaco's or Designer Holdings' dividend policies
before the merger. After the merger, as a holder of Warnaco shares, former
Designer Holdings shareholders will receive any dividends declared on such
Warnaco shares with a record date after the Merger. The current annual dividend
rate on Warnaco Common Stock is $0.32 per share.
 
     Pursuant to the Exchange Agreement, the Sellers have irrevocably waived
their right to receive any dividends declared on shares of Warnaco Common Stock
payable to holders of record on any date subsequent to October 14, 1997 (the
date the Exchange was consummated) and prior to the Effective Time.

               UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
 
     The following unaudited pro forma combined financial statements (the
'Unaudited Pro Forma Information') has been derived from the application of pro
forma adjustments to the combined historical financial statements of Warnaco and
Designer Holdings, which are incorporated by reference into this Joint Proxy
Statement/Prospectus. The Unaudited Pro Forma Information gives effect to the
Merger as if the Merger had occurred on (a) October 4, 1997 for purposes of the
Unaudited Pro Forma Combined Balance Sheet and (b) January 7, 1996 for purposes
of the Unaudited Pro Forma Combined Statements of Income for the year ended
January 4, 1997 and for the nine months ended October 4, 1997. The pro forma
adjustments are described in the accompanying notes to the unaudited pro forma
combined financial statements. The Unaudited Pro Forma Information is presented
for informational purposes only and does not purport to represent what the
financial position or results of operations for the combined companies would
actually have been had the Merger occurred on the dates specified or to project
the financial position or results of operations for the combined companies at
any future date or for any future periods.
 
     The Unaudited Pro Forma Information, including the notes thereto, should be
read in conjunction with the historical consolidated financial statements and
consolidated condensed financial statements of Warnaco and Designer Holdings,
including the notes thereto, incorporated by reference in this Joint Proxy
Statement/Prospectus. See 'Where You Can Find More Information' on page 69.
 
     The Merger will be accounted for using the purchase method of accounting.
The purchase price for the outstanding common stock of Designer Holdings,
including estimated fees and expenses related to the Merger, has been allocated
to the tangible and identifiable intangible assets and liabilities of Designer
Holdings based upon Warnaco's preliminary estimates of the fair value of the
assets acquired and the liabilities assumed. The remaining purchase price has
been allocated to the excess of cost over the fair value of the net assets
acquired ('Goodwill'), which is included in intangible and other assets, net in
the Unaudited Pro Forma Combined Balance Sheet. The pro forma adjustments
directly attributable to the Merger relate primarily to the amortization of
Goodwill and to the preliminary allocation of purchase price to the fair value
of the net assets acquired.
 
     The allocation of purchase price is subject to revision when additional
information concerning the asset and liability valuations becomes available.
Accordingly, the final purchase price allocation could be different from the
amounts reflected in the Unaudited Pro Forma Information. Final allocation of
the purchase price to intangibles, other than goodwill, and other assets or
liabilities could vary the related amortization period of the excess of cost
over the fair value of the net assets acquired.
 
     The Unaudited Pro Forma Information assumes that the Goodwill will be
amortized over a period of forty years, which is less than the remaining term
(including the renewal period) of the exclusive license to develop, source and
market designer sportswear collections under the Calvin Klein Jeans'r',
CK/Calvin Klein Jeans'r' and CK/Calvin Klein/Khakis'r' labels (collectively, the
'Jeans License') in specified territories. Warnaco believes that the intangible
assets acquired, principally the Jeans License, represent a scarce asset with a
life in excess of forty years. In addition, the Merger is expected to permit the
continued expansion of current lines of business and contribute to the
development of new businesses. Warnaco believes that it will benefit from the
Merger for an indeterminable period of time of at least forty years, and
therefore a forty-year amortization period is appropriate. Warnaco will perform
periodic reviews of its intangible assets, including Goodwill arising from the
Merger, to ensure that they are carried at recoverable amounts in light of the
then current business conditions. If the average life of the unallocated
purchase price decreased by ten years as a result of the final purchase price
allocation, amortization expense would increase by approximately $1.8 million
per year and decrease pro forma net income per share by approximately $0.03 and
$0.02 per share for the year ended January 4, 1997 and for the nine months ended
October 4, 1997, respectively.
 
     The Unaudited Pro Forma Information gives effect only to the adjustments
set forth in the accompanying notes thereto and does not reflect any cost
savings or other benefits anticipated by
 
                                       42

Warnaco's management as a result of the Merger. However the Unaudited Pro Forma
Information reflects certain identified costs associated with the consummation
of the Merger. Additional Merger-related costs may be incurred. For a discussion
of anticipated cost savings and other benefits of the Merger, see 'Risk
Factors', 'The Merger -- Warnaco's Reasons for the Merger; Recommendation of the
Warnaco Board', ' -- Expected Cost Savings from the Merger' and ' -- Cautionary
Statement Concerning Forward-Looking Statements'. To the extent that such
potential savings are realized, pro forma earnings per share would increase by
approximately $0.01 per share for each $1 million of pre-tax cost savings
ultimately realized for the periods specified.

     2. Reflects the elimination of historical amortization expense of Designer
Holdings related to the excess of cost over the fair value of the net assets
acquired included in the historical Statements of Income of approximately $2.8
million and $1.9 million for the fiscal year ended December 31, 1996 and nine
months ended September 30, 1997, respectively.
 
     3. Reflects amortization of the excess of cost over net assets acquired and
intangible assets of Warnaco of approximately $5.5 million and $4.1 million for
the fiscal year ended January 4, 1997 and for the nine months ended October 4,
1997, respectively, using the straight line method over forty years.
 
     4. Reflects non-cash interest expense related to accretion of the
Company-Obligated Mandatorily Redeemable Convertible Preferred Securities of
Designer Finance Trust Holding Solely Convertible Debentures (for purposes of
these notes, the 'Securities') issued in November 1996 to face value by their
maturity date, using the effective interest rate method. The allocation of
purchase price to the fair value of assets acquired and liabilities assumed is
expected to result in a decrease in the recorded value of the Securities of
approximately $19.5 million. See Note 5 of Notes to Unaudited Pro Forma Combined
Balance Sheet.
 
     5. Represents the issuance of 10,413,144 shares of Warnaco Common Stock in
exchange for 32,139,334 shares of Designer Holdings Common Stock currently
outstanding and the related adjustments to the weighted average number of shares
of common stock outstanding. See Note 3 of Notes to Unaudited Pro Forma Combined
Balance Sheet.
 
     6. Reflects the impact of 1,822,000 weighted average equivalent shares of
Warnaco Common Stock outstanding not included in the calculation of Warnaco's
income (loss) per common share for the fiscal year ended January 4, 1997 as the
effect on income (loss) per share was anti-dilutive.
 
     7. Warnaco net revenues includes approximately $6.2 million and $2.7
million of merchandise sold to Designer Holdings for the nine months ended
October 4, 1997 and for the year ended January 4, 1997, respectively. The
intercompany inventory profit related to the merchandise is not considered
material for purposes of the Unaudited Pro Forma Combined Statements of Income.
 
     8. Fully diluted earnings per share is not presented, as the effect of
including the Securities in earnings per share is not material.

              NOTES TO UNAUDITED PRO FORMA COMBINED BALANCE SHEET
 
     1. The Unaudited Pro Forma Combined Balance Sheet at October 4, 1997
represents the historical consolidated balance sheet of Warnaco at October 4,
1997 and the historical consolidated balance sheet of Designer Holdings at
September 30, 1997. The Unaudited Pro Forma Combined Balance Sheet has been
prepared assuming that the Merger occurred as of October 4, 1997 using the
purchase method of accounting.
 
     2. Reflects the use of $50.0 million of Designer Holdings cash on hand to
repay outstanding debt of Warnaco.
 
     3. Records the issuance of 10,413,144 shares of Warnaco Common Stock valued
at $33 15/16 per share totalling approximately $353.4 million in exchange for
32,139,334 shares of Designer Holdings Common Stock currently outstanding
pursuant to the Exchange Agreement and the Merger Agreement. The exchange ratio
used is 0.324 of a share of Warnaco Common Stock for each share of Designer
Holdings Common Stock outstanding as set forth in the Merger Agreement. This
adjustment also reflects the elimination and consolidation entry related to
consolidating Designer Holdings with Warnaco. The purchase price was allocated

                   INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     Certain Designer Holdings officers and key employees, as well as all five
directors at the time the Merger Agreement was approved, may be deemed to have
interests in the Merger that are different from, or in addition to, your
interests as stockholders of Designer Holdings generally. The Designer Holdings
Board was aware of these interests and considered them, in addition to the
matters described under 'The Merger -- Information and Factors Considered by the
Designer Holdings Board; Recommendation of the Designer Holdings Board', in
approving the Merger Agreement, the Exchange Agreement and the transactions
contemplated thereby. These interests are described below.
 
INTERESTS OF OFFICERS AND DIRECTORS OF DESIGNER HOLDINGS IN THE EXCHANGE
 
     Arnold H. Simon, President, Chief Executive Officer and a director of
Designer Holdings, is a member of, and owns a 47.3% interest in, New Rio. Mr.
Simon and his wife, Debra Simon, Executive Vice President and a director of
Designer Holdings at the time the Merger was approved, are the managing members
of A.S. Enterprises, L.L.C., a Delaware limited liability company that is a
managing member of, and owns a 1.8% interest in, New Rio. In addition, Merril M.
Halpern, a director of Designer Holdings, and A. Lawrence Fagan, a director of
Designer Holdings at the time the Merger was approved, are executive officers of
Charterhouse, which indirectly controls CEP II. CEP II is a managing member of,
and owns an approximately 49.9% interest in, New Rio. As a result of the
Exchange, New Rio currently owns approximately 9% of the outstanding Warnaco
Common Stock.
 
SIMON EMPLOYMENT AGREEMENTS
 
     Pursuant to an employment agreement dated as of January 1, 1996 between
Designer Holdings and Arnold H. Simon (the '1996 Simon Employment Agreement'),
Mr. Simon had the right to terminate the 1996 Simon Employment Agreement at any
time for 'Good Reason'. The 1996 Simon Employment Agreement provided that Good
Reason was deemed to exist upon the occurrence of a merger, consolidation or
other business combination of Designer Holdings (other than such a transaction
in which the Designer Holdings stockholders continue to own beneficially more
than 80% of the then outstanding voting securities of Designer Holdings) or any
person or group (as such term is defined under the Exchange Act), or group of
related persons (other than CEP II), owning beneficially more than 50% of the
then outstanding voting stock of Designer Holdings. The 1996 Simon Employment
Agreement provided that upon a termination by Mr. Simon for Good Reason, Mr.
Simon would be entitled, in addition to any accrued base salary and annual bonus
earned but not yet paid, a lump sum payment in an amount equal to the sum of (i)
Mr. Simon's highest annual base salary during the term of the 1996 Simon
Employment Agreement multiplied by 2.99 (299%) and (ii) Mr. Simon's average
annual bonus paid or payable with respect to the then immediately preceding
three fiscal years multiplied by 2.99 (299%); provided that the amount payable
would not exceed $9 million in the aggregate and would be reduced to the extent
required so that Mr. Simon would not incur any obligation to pay any excise tax
pursuant to Section 4999 of the Code (the 'Excise Tax Reduction'). Prior to the
execution of the Merger Agreement and the Exchange Agreement, Mr. Simon informed
Designer Holdings of his intent to terminate the 1996 Simon Employment Agreement
for Good Reason upon consummation of the Exchange.
 
     In connection with the execution of the Merger Agreement and the Exchange
Agreement, on September 25, 1997, Mr. Simon entered into an agreement (the 'New
Simon Employment Agreement') with Warnaco pursuant to which Mr. Simon is
employed as President and Chief Executive Officer of the Designer Holdings
subsidiary of Warnaco for a two-year term, which became effective upon
consummation of the Exchange. Simultaneously with the consummation of the
Exchange, in connection with the simultaneous termination of the 1996 Simon
Employment Agreement, Designer Holdings made a cash payment to Mr. Simon in the
amount of approximately $2.6
mil-
 
                                       49

<PAGE>
lion, representing $9 million, less approximately $1.2 million as a result of
the Excise Tax Reduction, $2.9 million in withholding and other taxes and $2.3
million in loans and other amounts owed by Mr. Simon to Designer Holdings.
 
     Pursuant to the New Simon Employment Agreement, Mr. Simon is entitled to
receive a base salary of $1,500,000 per year and a bonus (the 'Bonus'), to the
extent Designer Holdings achieves certain EBIT targets for the 1998 and 1999
fiscal years, of either 100% or 125% of the actual base salary paid to Mr. Simon
for the prior fiscal year. Commencing in fiscal 1998, Mr. Simon will also be
eligible to participate in Warnaco's Supplemental Incentive Compensation Plan.
Combined payment of the bonus amount and amounts under the Supplemental
Incentive Compensation Plan are limited to 150% of base salary earned for the
prior fiscal year. Mr. Simon is also entitled to participate in the other
benefit plans available to employees of Warnaco or Designer Holdings. Mr. Simon
is also entitled to certain other benefits and perquisites, including severance
payments in the event that he is terminated by Warnaco without Cause (as defined
in the New Simon Employment Agreement), as well as in the event that he
voluntarily terminates his employment at least six months after the effective
date of the New Simon Employment Agreement. Pursuant to the New Simon Employment
Agreement, Mr. Simon is also eligible to participate in Warnaco's Amended and
Restated 1993 Stock Plan (the 'Warnaco Stock Plan'). Pursuant to the Warnaco
Stock Plan, Mr. Simon will be granted on or prior to January 31, 1998, an option
to purchase 100,000 shares, priced as of the date of such grant, of Warnaco
Common Stock.
 
TREATMENT OF DESIGNER HOLDINGS STOCK OPTIONS
 
     Pursuant to the Designer Holdings 1996 Stock Option and Incentive Plan and
the 1996 Outside Director Stock Option Plan (collectively, the 'Stock Plans'),
all outstanding stock options become immediately exercisable upon a Change in
Control of Designer Holdings. The Stock Plans define Change in Control to
include, among other things, approval by the stockholders of Designer Holdings
of a merger or consolidation of Designer Holdings with any other corporation.
Each outstanding option (each, a 'Designer Holdings Stock Option') granted by
Designer Holdings to purchase shares of Designer Holdings Common Stock under the
Stock Plans was cancelled, effective upon the closing of the Exchange, if the
exercise price of such Designer Holdings Stock Option equaled or exceeded $11
per share. In exchange for the cancellation of such Designer Holdings Stock
Options and to compensate certain employees in lieu of granting options,
Designer Holdings has committed to pay, upon the consummation of the Merger, an
aggregate of $3.5 million to those employees whose Designer Holdings Stock
Options are so cancelled. The amounts of the payments to each of the named
executive officers (other than Arnold and Debra Simon, who will not receive such
payments) are as follows: Maurice Dickson (who is no longer employed by Designer
Holdings) -- $550,000; Daniel Gladstone -- $450,000; and David
Fidlon -- $350,000. New Rio has also agreed to provide payments in equal amounts
to such employees subsequent to consummation of the Merger or, if earlier, upon
termination of the Merger Agreement.
 
     Any outstanding Designer Holdings Stock Option with an exercise price below
$11 per share will be deemed to constitute an option (each, a 'Warnaco Stock
Option') to acquire, on the same terms and conditions as were applicable to the
Designer Holdings Stock Option, that number of shares of Warnaco Common Stock
equal to the product of (i) the number of shares of Designer Holdings Common
Stock issuable upon exercise of such Designer Holdings Stock Option and (ii) the
Exchange Ratio, at a price per share equal to (1) the aggregate exercise price
for the shares of Designer Holdings Common Stock otherwise purchasable pursuant
to such Designer Holdings Stock Option divided by (2) the number of shares of
Warnaco Common Stock issuable per share of Designer Holdings Common Stock upon
exercise of such Designer Holdings Stock Option; provided that after aggregating
all the shares subject to Designer Holdings Stock Options of any holder, any
fractional share of Warnaco Common Stock resulting from such calculation will be
rounded down to the nearest whole share. As a result of the foregoing, upon the
consummation of the Merger, the outstanding Designer Holdings Stock Options will
be deemed to constitute
 
                                       50

Warnaco Stock Options to acquire an aggregate of 82,944 shares of Warnaco Common
Stock, 81,972 of which will be held by Peter Damon Brown and 972 of which will
be held by the estate of Fred Zuckerman. Mr. Brown is a director of, and
consultant to, Designer Holdings, and Mr. Zuckerman, prior to his death, was a
director of Designer Holdings.
 
INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE
 
     Pursuant to the Merger Agreement, Designer Holdings, as the surviving
corporation in the Merger, has agreed to indemnify all present and former
directors and officers of Designer Holdings and its subsidiaries for a period of
six years after the effective time of the Merger for acts or omissions occurring
prior to such effective time to the fullest extent now provided in their
respective certificates of incorporation or by-laws and to the extent such acts
or omissions are uninsured. Designer Holdings has also agreed to indemnify any
such person in the event that Designer Holdings' insurance does not fully
indemnify such person. In the event that Designer Holdings' insurance is
insufficient to fully indemnify any such person, Warnaco will, consistent with
applicable law, indemnify such person to the same extent as provided in Designer
Holdings' certificate of incorporation and by-laws. Warnaco has also agreed to
indemnify the Sellers for all claims asserted by other stockholders of Designer
Holdings, including derivative lawsuits, costs of defense, settlement, judgment
and other amounts, in connection with the transactions contemplated by the
Merger Agreement and the Exchange Agreement alleging any breach of fiduciary
duty on the part of New Rio as a result of the transactions contemplated by the
Exchange Agreement to the extent such indemnification is consistent with
applicable law. As described under 'The Merger -- Certain Stockholder
Litigation', the directors of Designer Holdings are currently parties to
litigation relating to the Merger for which they are entitled to indemnification
by Designer Holdings as set forth above.
 
     Warnaco has further agreed to cause to be maintained for a period of six
years from the Effective Time Designer Holdings' current directors' and
officers' insurance and indemnification policy (or at Warnaco's option a
replacement policy having terms no less advantageous than Designer Holdings'
current policy) to the extent that it provides coverage for events occurring
prior to such effective time for all persons who are or were directors and
officers of Designer Holdings on the date of the Merger Agreement, so long as
the annual premium for such insurance policy would not exceed 150% of the last
annual premium paid prior to the date of the Merger Agreement. See 'The Merger
Agreement -- Certain Covenants -- Indemnification and Insurance of Designer
Holdings Directors and Officers'.
 
                              THE MERGER AGREEMENT
 
     The description of the Merger Agreement set forth below is qualified in its
entirety by reference to the Merger Agreement, a copy of which is attached as
Annex A to this Joint Proxy Statement/Prospectus and incorporated herein by
reference.
 
GENERAL
 
     The Merger Agreement contemplates the merger of WAC with and into Designer
Holdings, with Designer Holdings surviving the Merger as a wholly owned
subsidiary of Warnaco (the 'Surviving Corporation'). The Merger will become
effective upon the filing of, or at any subsequent time stated in, the
Certificate of Merger to be filed with the Secretary of State of the State of
Delaware. It is anticipated that the filing will be made as soon as practicable
after the closing under the Merger Agreement, which, unless the parties to the
Merger Agreement otherwise agree, is to occur no later than the second business
day after the conditions precedent to the Merger set forth in the Merger
Agreement have been satisfied or waived.

MERGER CONSIDERATION
 
     The Merger Agreement provides that each share of Designer Holdings Common
Stock outstanding immediately prior to the Effective Time (except as described
in the next sentence) will, at the Effective Time, be converted into the right
to receive 0.324 of a fully paid and non-assessable share of Warnaco Common
Stock. All shares of Designer Holdings Common Stock that are owned by Designer
Holdings as treasury stock or otherwise and any shares of Designer Holdings
Common Stock owned by Warnaco or any subsidiary of Warnaco or by any subsidiary
of Designer Holdings will, at the Effective Time, be cancelled and retired and
will cease to exist and no payment will be made for such shares.
 
TREATMENT OF TOPRS AND CONVERTIBLE DEBENTURES
 
     Designer Holdings has outstanding $123,711,350 of its Convertible
Debentures which are held by its wholly owned subsidiary Designer Finance Trust.
Designer Finance Trust has outstanding 2,400,000 of its TOPrS. The Convertible
Debentures and the TOPrS are convertible into 2.126 shares of Designer Holdings
Common Stock (.6888 shares of Warnaco Common Stock after giving effect to the
Merger, determined by multiplying 2.126, the conversion ratio of the TOPrS, by
0.324, the Exchange Ratio), or 1,653,177 shares in the aggregate, at an
effective conversion price of $23.52 per share of Designer Holdings Common Stock
($72.59 per share of Warnaco Common Stock after giving effect to the Merger).
Under the terms of the Merger Agreement, Warnaco and Designer Holdings have
agreed to take such steps as are necessary to ensure that the holders of the
TOPrS will, after the Effective Time, have the right to convert the TOPrS into
shares of Warnaco Common Stock on the terms and conditions set forth in the
indenture relating to the Convertible Debentures. Warnaco currently expects that
following the consummation of the Merger, Warnaco will enter into a guarantee of
Designer Holdings' obligations to the holders of the TOPrS and an indenture
supplemental to such indenture pursuant to which it will become jointly and
severally liable with Designer Holdings for the Convertible Debentures. Neither
the Warnaco stockholders nor the Designer Holdings stockholders are being asked
to approve any of the foregoing changes relating to the TOPrS.
 
TREATMENT OF DESIGNER HOLDINGS STOCK OPTIONS
 
     Pursuant to the Merger Agreement, each option granted by Designer Holdings
to purchase shares of Designer Holdings Common Stock under the Stock Plans
outstanding immediately prior to the Effective Time will be adjusted to provide
that at the Effective Time, such stock option will be cancelled if the exercise
price thereof equals or exceeds $11 per share. With respect to any Designer
Holdings Stock Options not cancelled in accordance with the preceding sentence,
such Designer Holdings Stock Options will be deemed to constitute options to
acquire, on the same terms and conditions as were applicable under such Designer
Holdings Stock Option, a number of shares of Warnaco Common Stock equal to the
product of (1) the number of shares of Designer Holdings Common Stock issuable
upon exercise of such Designer Holdings Stock Option and (2) the Exchange Ratio,
at a price per share equal to (1) the aggregate exercise price for the shares of
Designer Holdings Common Stock otherwise purchasable pursuant to such Designer
Holdings Stock Option divided by (2) the number of shares of Warnaco Common
Stock issuable per share of Designer Holdings Common Stock upon exercise of such
Designer Holdings Stock Option; provided that after aggregating all the shares
subject to Designer Holdings Stock Options of any holder, any fractional share
of Warnaco Common Stock resulting from such calculation will be rounded down to
the nearest whole share. Because the terms of certain Designer Holdings Stock
Options will result in those options becoming exercisable immediately upon a
change in control, the options to acquire Warnaco common stock, into which the
Designer Holdings Stock Options will be deemed to have been converted, likewise
will be exercisable immediately at the Effective Time. For additional
information on Designer Holdings Stock Options, see 'Interests of Certain
Persons in the Merger -- Treatment of Designer Holdings Stock Options'.
 
                                       52

<PAGE>
EXCHANGE OF SHARES
 
     Prior to the Effective Time, Warnaco will appoint an agent (the 'Exchange
Agent') for the purpose of exchanging certificates representing shares of
Designer Holdings Common Stock for certificates representing shares of Warnaco
Common Stock. Warnaco will deposit certificates representing shares of Warnaco
Common Stock with the Exchange Agent for conversion of shares as described above
under ' -- Merger Consideration'. Promptly after the Effective Time, Warnaco or
the Exchange Agent will send each holder of Designer Holdings Common Stock a
letter of transmittal for use in the exchange and instructions explaining how to
surrender certificates to the Exchange Agent. Holders of Designer Holdings
Common Stock that surrender their certificates to the Exchange Agent, together
with a properly completed letter of transmittal, will receive Warnaco Common
Stock certificates representing such number of shares as such holders are
entitled in accordance with the Exchange Ratio except as set forth in the next
following paragraph. Holders of unexchanged shares of Designer Holdings Common
Stock will not be entitled to receive any dividends or other distributions
payable by Warnaco after the Effective Time until their certificates are
surrendered. Upon surrender, however, subject to applicable laws, such holders
will receive accumulated dividends and distributions payable on the related
shares of Warnaco Common Stock subsequent to the Effective Time, without
interest, together with cash in lieu of fractional shares (paid as described in
the following paragraph).
 
     No fractional shares of Warnaco Common Stock will be issued in the Merger.
In lieu of any such fractional shares, each holder of Designer Holdings Common
Stock who otherwise would be entitled to receive a fractional share of Warnaco
Common Stock pursuant to the Merger will be paid an amount in cash equal to such
holder's proportionate interest in the net proceeds from the sale or sales in
the open market by the Exchange Agent, on behalf of all such holders, of the
aggregate fractional shares of Warnaco Common Stock (the 'Excess Shares'), if
any, that would have been issued in the Merger. As soon as practicable following
the Effective Time, the Exchange Agent will determine the number of Excess
Shares, if any, and the Exchange Agent, as agent of such holders, will sell any
such Excess Shares at the then prevailing prices on the NYSE. The sale of the
Excess Shares by the Exchange Agent will be executed on the NYSE through one or
more member firms of the NYSE and will be executed in round lots to the extent
practicable. The proceeds from such sale or sales available for distribution to
such holders will be reduced by the compensation payable to the Exchange Agent
and the expenses incurred by the Exchange Agent, in each case, in connection
with such sale or sales of the Excess Shares, including all related commissions,
transfer taxes and other out-of-pocket transaction costs. Until the net proceeds
of such sale or sales have been distributed to such holders, the Exchange Agent
will hold such proceeds in trust for such holders. As soon as practicable after
the determination of the amount of cash, if any, to be paid to such holders in
lieu of any fractional shares of Warnaco Common Stock, the Exchange Agent will
make available such amounts, without interest, to such holders who have
surrendered their certificates.
 
     In contrast to the treatment of fractional shares in the Merger, the
Exchange Agreement provided that to the extent the aggregate number of shares of
Warnaco Common Stock to be issued to New Rio was to result in the issuance by
Warnaco of a fractional share, such fractional share was to be rounded to the
nearest whole number. As a result of such calculation, the aggregate shares
issued to New Rio was reduced by 0.23 of a Warnaco share, which as of the close
of business on October 14, 1997, the closing date for the Exchange, had a value
of $7.3169.

authorizing, committing or agreeing to take any of the foregoing actions.
 
     Designer Holdings has further agreed that neither it nor its subsidiaries
will, without the written consent of Warnaco, adopt or amend any arrangement for
the benefit or welfare of any employee, director or former director or employee
of Designer Holdings, increase any compensation or benefits of any director,
employee, or former director or employee or pay any benefit not required by any
existing arrangement. Designer Holdings has also agreed that neither it nor any
of its subsidiaries will grant any new or modified severance or termination
arrangement or increase any benefits payable under its severance or termination
pay policies in effect at the time of entering into the Merger Agreement.
 
     Interim Operations of Warnaco. From September 25, 1997 until the Effective
Time, Warnaco is required, to the extent consistent with its reasonable
commercial judgment and to the extent material, to use its reasonable best
efforts to preserve intact its and its subsidiaries business organizations, keep
available the services of their current officers and employees and preserve
their relationships with customers, suppliers, licensors, licensees,
advertisers, distributors and others having business dealings with them to the
end that their goodwill and ongoing businesses shall be unimpaired at the
Effective Time. Without limiting the foregoing, during this period, Warnaco will
not, without the prior written consent of Designer Holdings, adopt a plan of
complete or partial liquidation or dissolution or agree to enter into any
merger, consolidation or other significant corporate transaction.
 
     No Solicitation by Designer Holdings. Designer Holdings has covenanted in
the Merger Agreement that it will not, and that it will cause its
representatives and subsidiaries not to, directly or indirectly, take any action
to solicit, initiate or encourage any inquiries, offers or proposals or any
 
                                       54
 


<PAGE>

<PAGE>
indications of interest, regarding any merger, sale of substantial assets, sale
of shares of capital stock (including by way of a tender offer) or similar
transactions involving Designer Holdings or any significant subsidiary of
Designer Holdings other than the Merger (any of the foregoing inquiries or
proposals being referred to herein as an 'Acquisition Proposal') or participate
in negotiations or discussions concerning, or provide any nonpublic information
to any person relating thereto; provided, that prior to the consummation of the
Exchange, Designer Holdings would have been permitted to participate in
negotiations or discussions with, and provide nonpublic information to, any
person concerning an Acquisition Proposal submitted in writing to the Designer
Holdings Board if (i) such Acquisition Proposal were not solicited, initiated or
encouraged in violation of the Merger Agreement, (ii) the Designer Holdings
Board in its good faith judgment, believed that such Acquisition Proposal was
reasonably likely to result in an Alternative Transaction that would be more
favorable to the stockholders of Designer Holdings than the Merger or the Merger
Agreement, (iii) failing to take such action would have constituted a breach of
the Designer Holdings Board's fiduciary duties under applicable law and (iv)
prior to providing any nonpublic information to any such person, such person
enters into a confidentiality agreement substantially similar to the
confidentiality agreement entered into with Warnaco. The Designer Holdings Board
further agreed not to recommend that the stockholders of Designer Holdings
tender or exchange any shares of Designer Holdings Common Stock in connection
with any tender or exchange offer unless failing to make such a recommendation
would constitute a breach of the Designer Holdings Board's fiduciary duties
under applicable law. Designer Holdings is required to notify Warnaco promptly
if any Acquisition Proposal is made and keep Warnaco advised of all material
developments concerning such Acquisition Proposal. 'Alternative Transaction'
means any of (i) a transaction or series of transactions pursuant to which any
person (or group of persons) other than Warnaco or its subsidiaries (a 'Third
Party') acquires or would acquire more than 15% of the then outstanding shares
of Designer Holdings Common Stock, whether from Designer Holdings, New Rio or
pursuant to a tender offer or exchange offer or otherwise, (ii) any direct or
indirect acquisition or proposed acquisition of Designer Holdings or any of its
significant subsidiaries by means of a merger or other business combination
transaction (including any so-called 'merger of equals' and whether or not
Designer Holdings or any of its significant subsidiaries is the entity surviving
any such merger or business combination transaction) or (iii) any other
transaction pursuant to which any Third Party acquires or would acquire control
of assets (including for this purpose the outstanding equity securities of
subsidiaries of Designer Holdings and any entity surviving any merger or
business combination including any of them) of Designer Holdings or any of its
subsidiaries having a fair market value equal to more than 15% of the fair
market value of all the assets of Designer Holdings and its subsidiaries, taken
as a whole, immediately prior to such transaction.
 
     Designer Holdings Board's Covenant to Recommend. The Designer Holdings
Board has agreed to recommend to Designer Holdings stockholders the approval and
adoption of the Merger Agreement and the Merger. The Designer Holdings Board is
not permitted to withdraw, amend or modify such recommendation in a manner
adverse to Warnaco.
 
     Warnaco Board's Covenant to Recommend. Warnaco's Board is obligated to call
a meeting of its stockholders for the purpose of voting on the issuance of
shares of Warnaco Common Stock in the Merger, the Exchange and upon any
conversions of the Convertible Debentures and, at such meeting, to recommend
approval by Warnaco stockholders of such issuance of shares of Warnaco Common
Stock.
 
     Reasonable Best Efforts. Each of the parties has agreed to use its
reasonable best efforts to take all actions and do all things necessary or
advisable to consummate and make effective the Merger and the other transactions
contemplated by the Merger Agreement.
 
     Certain Employee Benefits Matters. The Merger Agreement provides that
Warnaco will (subject to certain exceptions) provide that all retained employees
of Designer Holdings and its subsidiaries not subject to collective bargaining
agreements will participate in Designer Holdings' existing
 
                                       55
 


<PAGE>

<PAGE>
employee benefit plans (other than stock-based plans) or, at Warnaco's option,
participate in Warnaco's employee benefit plans and arrangements (other than
those plans that are the subject of collective bargaining) on a basis no less
favorable in the aggregate than similarly situated employees of Warnaco and its
subsidiaries and, with respect to employees who are the subject of collective
bargaining agreements, they will be provided with all benefits and other terms
and conditions of employment in accordance with the applicable collective
bargaining agreement.
 
     Indemnification and Insurance of Designer Holdings Directors and Officers.
Pursuant to the Merger Agreement, (i) the Surviving Corporation (and, to the
extent the Surviving Corporation's insurance is not sufficient, Warnaco) has
agreed to indemnify, after the Effective Time and for six years thereafter, all
directors and officers of Designer Holdings and its subsidiaries, to the fullest
extent provided in the respective certificates or incorporation or by-laws and
to the extent consistent with applicable law, for acts and omissions occurring
prior to the Effective Time, to the extent such acts or omissions are uninsured,
and (ii) Warnaco has agreed to indemnify, after the Effective Time and for six
years thereafter, the Sellers, to the extent such indemnification is consistent
with applicable law, for all claims asserted by any other Designer Holdings
stockholder alleging any breach of fiduciary duty in connection with the
transactions contemplated by the Merger Agreement and the Stock Exchange
Agreement. The Merger Agreement also provides that for a period of six years
after the Effective Time, Warnaco will cause to be maintained in effect Designer
Holdings' existing policy of directors' and officers' liability insurance (or a
replacement policy having terms no less advantageous) with respect to events
occurring at or prior to the Effective Time; provided that if the annual premium
for such insurance during such six-year period exceeds 150% of the annual
premiums paid by Designer Holdings as of September 25, 1997 for such insurance
(such 150% amount, the 'Maximum Premium') then Warnaco will provide the most
advantageous directors' and officers' insurance coverage then available for an
annual premium equal to the Maximum Premium. See 'Interests of Certain Persons
in the Merger -- Indemnification; Directors' and Officers' Insurance'.
 
     Board of Directors. Pursuant to the Merger Agreement, upon the closing of
the Exchange Warnaco designated four directors to be appointed to the Designer
Holdings Board, which, upon the resignation of two existing directors of
Designer Holdings resulted in Warnaco controlling a majority of the Designer
Holdings Board. The Designer Holdings Board is required to have, until the
Effective Time, at least one director who was a director of Designer Holdings
prior to the closing of the Exchange (the 'Continuing Director'); provided,
however, that if no Continuing Director remains, the other directors may
designate an individual to fill such vacancy who will not be an officer,
director, employee or affiliate of Warnaco or any of its affiliates and will
otherwise be an 'independent director' under the rules of the NYSE (such
designee to be deemed to be a Continuing Director for purposes of the Merger
Agreement). Prior to the Effective Time, any termination or amendment of the
Merger Agreement by Designer Holdings, any extension by Designer Holdings of
time for the performance of any of the obligations or other acts of Warnaco or
any waiver or assertion of any of Designer Holdings' rights pursuant to the
Merger Agreement will require the concurrence of a majority of the Continuing
Directors.
 
     Voting of Designer Holdings Shares. Warnaco has agreed to vote (or cause to
be voted) in favor of the Designer Holdings Merger Proposal all shares of
Designer Holdings Common Stock owned by it or its subsidiaries on the record
date for the Designer Holdings Meeting.
 
     Anti-Dilution. In connection with the Exchange, Designer Holdings has
agreed that in the event that prior to the earlier of the Effective Time and two
years after the closing of the Exchange the Designer Holdings shares acquired by
Warnaco in the Exchange cease to represent a majority of the outstanding
Designer Holdings Common Stock as a result of issuances of Designer Holdings
Common Stock by Designer Holdings, upon notice from Warnaco Designer Holdings
will sell to Warnaco at a per share price in cash equal to the product of 0.324
and the average closing price of Warnaco common stock on the NYSE for the five
consecutive trading days prior to the date of such notice, such number of shares
of Designer Holdings Common Stock as is necessary so
 
                                       56
 


<PAGE>

<PAGE>
that the total number of shares of Designer Holdings Common Stock held by
Warnaco represents a majority of the outstanding Designer Holdings shares.
 
     Certain Other Covenants. The Merger Agreement contains certain other
customary covenants of the parties, including covenants relating to: preparation
and distribution of this Joint Proxy Statement/Prospectus; public announcements;
delivery of accountants' letters; access to information; cooperation;
confidential treatment of nonpublic information; and delivery by Designer
Holdings of 'affiliates' letters' pursuant to Rule 145 under the Securities Act.
 
     The Merger Agreement also contains certain covenants of Warnaco, including
covenants requiring Warnaco to use its reasonable best efforts to list the
shares of Warnaco Common Stock to be issued in the Merger and under certain
stock plans of Designer Holdings on the NYSE at or prior to the Effective Time,
subject to official notice of issuance.
 
CERTAIN REPRESENTATIONS AND WARRANTIES
 
     The Merger Agreement contains substantially reciprocal representations and
warranties made by Warnaco and Designer Holdings to each other as to, among
other things: due organization and good standing; ownership of subsidiaries;
capitalization; corporate authorization to enter into the contemplated
transactions; filings with the SEC; information provided by it for inclusion in
this Joint Proxy Statement/Prospectus; absence of certain material changes since
the date of the most recent audited financial statements; litigation; compliance
with laws; certain payments to employees as a result of the transactions

Designer Holdings only, certain labor matters; employee benefit matters; the
inapplicability of Section 203 of the DGCL in connection with the Exchange and
the transactions contemplated by the Merger Agreement; environmental matters;
agreements restricting the ability of Designer Holdings to compete; real

have no effect, without any liability or obligation on the part of Warnaco, WAC
or Designer Holdings, other than under the provisions of the Merger Agreement

expenses, the exemption of Warnaco and WAC from Section 203 of the DGCL with
respect to Designer Holdings, the provision described above under ' -- Certain

Agreement and the transactions contemplated thereby.
 
AMENDMENTS; WAIVERS
 
     Any provision of the Merger Agreement may be amended or waived prior to the
Effective Time if (a) the amendment or waiver is in writing and signed, in the
case of an amendment, by Designer Holdings and Warnaco or, in the case of a
waiver, by the party against whom the waiver is to be effective, and (b) such
amendment or waiver is approved by a majority of the Continuing Directors;
provided that after the approval of the Merger Agreement by the stockholders of
Designer Holdings or Warnaco, there shall be made no amendment that by law
requires further approval by stockholders without the further approval of such
stockholders.
 
                             THE EXCHANGE AGREEMENT
 
     As an inducement and a condition to Warnaco and WAC entering into the
Merger Agreement, the Sellers entered into the Exchange Agreement with Warnaco.
The summary of the Exchange Agreement set forth below is qualified in its
entirety by reference to the Exchange Agreement, a copy of which is attached as
Annex B to this Joint Proxy Statement/Prospectus and incorporated herein by
reference.
 
     Transfer of Shares. Pursuant to the Exchange Agreement, prior to the
closing of the Exchange, New Rio transferred 225,374 shares of Designer Holdings
Common Stock to one of the members of New Rio. Such member has remained fully
subject to, and is obligated to comply with and is entitled to the benefits of,
all of the covenants and agreements contained in the Exchange Agreement and
applicable to New Rio, including the obligation to vote his Warnaco Shares in
favor of the Warnaco Merger Proposal.
 
     The Exchange. Pursuant to the Exchange Agreement, on October 14, 1997, New
Rio and the Seller referred to under ' -- Transfer of Shares' above transferred
all of the 16,483,868 shares of Designer Holdings Common Stock owned by them to
Warnaco in exchange for 5,267,752 and 73,021 shares of Warnaco Common Stock,
respectively, calculated in accordance with the Exchange
 
                                       59

Ratio. The shares of Warnaco Common Stock issued to New Rio and such Seller
pursuant to the Exchange are referred to herein as the 'Exchange Shares.'
 
     No Solicitation by Sellers. The Sellers have covenanted in the Exchange
Agreement that they will not, and that they will cause their representatives and
subsidiaries not to, directly or indirectly, take any action to solicit,
initiate or encourage any inquiries, offers or proposals or any indications of
interest, regarding any merger, sale of substantial assets, sale of shares of
capital stock (including by way of a tender offer) or similar transactions
involving Designer Holdings or any significant subsidiary of Designer Holdings
other than the Merger or participate in negotiations or discussions concerning,
or provide any nonpublic information to any person relating to, any Acquisition
Proposal. The Sellers are required to notify Warnaco promptly if any such
inquiry or proposal is made and keep Warnaco apprised of all material
developments concerning any such inquiry or proposal.
 
     Transfer of Shares of Warnaco Common Stock. The Sellers have agreed not to,
directly or indirectly, offer, sell, transfer, tender, pledge or encumber,
assign or otherwise dispose of any shares of Warnaco Common Stock (a) until the
earlier of (i) such time at or after the Effective Time that is no earlier than
the time when holders of Designer Holdings Common Stock can sell the shares of
Warnaco Common Stock issued pursuant to the Merger (without giving effect to any
restrictions under applicable securities laws) and (ii) the termination of the
Merger Agreement in accordance with its terms, (b) unless and until the same are
registered under the Securities Act and any applicable state securities laws, or
unless an exemption from such registration is available and (c) other than in
accordance with the terms of any letter entered into for tax purposes relating
to restrictions on selling the Exchange Shares (a 'Lock-Up Letter'), including
the letter dated as of October 14, 1997 among the Sellers and Warnaco pursuant
to which the Sellers agreed not to sell, transfer or otherwise dispose of in
excess of 80% of the Warnaco Shares acquired in the Exchange for a period of at
least one year from the Effective Time.
 
     Standstill. Each Seller has agreed that, until such Seller ceases to
beneficially own at least 25% of the Exchange Shares acquired by it or him in
the Exchange, such Seller will not (a) acting alone or in concert with others,
seek to affect or influence the control of Warnaco's management or Board or the
business, operations or policies of Warnaco; (b) deposit any shares of Warnaco
Common Stock or securities exercisable or exchangeable or convertible into
shares of Warnaco Common Stock, or other securities having the right to vote
generally with shares of Warnaco Common Stock (collectively 'Warnaco Voting
Securities') in a voting trust or subject any Warnaco Voting Securities to any
proxy, arrangement or agreement with respect to the voting of such Warnaco
Voting Securities or other agreement having similar effect; (c) initiate or
propose any stockholder proposal or make, or in any way, participate in,
directly or indirectly, any 'solicitation' of 'proxies' to vote, other than in
connection with the Merger and the Merger Agreement, or intentionally seek in an
organized fashion to influence any person with respect to the voting of, any
Warnaco Voting Securities in a manner inconsistent with the position of
Warnaco's Board or become a 'participant' in a 'solicitation' (as such terms are
defined in Regulation 14A under the Securities Exchange Act of 1934, as amended
(the 'Exchange Act'), as in effect on September 25, 1997) in opposition to the
recommendation of the majority of the directors of Warnaco with respect to any
matter; (d) join a partnership, limited partnership, syndicate or other group,
or otherwise act in concert with any other person, for the purpose of acquiring,
holding, voting or disposing of Warnaco Voting Securities, or, otherwise become
a 'person' within the meaning of Section 13(d)(3) of the Exchange Act relating
to any of the matters described in clauses (a), (b) or (c); or (e) take any
other action inconsistent with the provisions described above.
 
     Registration Rights. Warnaco has agreed to use its reasonable best efforts
to file and have declared effective as soon as practicable following the
Effective Time a registration statement under the Securities Act for resales of
the shares of Warnaco Common Stock issued to New Rio in the Exchange and not
subject to a Lock-Up Letter. Upon the request of New Rio and following the
termination of any Lock-Up Letter, Warnaco has agreed to use its reasonable best
efforts to add to such registration statement Exchange Shares that had been
subject to any such Lock-Up
 
                                       60
 


<PAGE>

<PAGE>
Letter. Notwithstanding anything else contained in the Exchange Agreement,
Warnaco is obligated to keep such registration statement effective until the
earliest of (i) 24 months after the Effective Time, (ii) such time as all shares
of Warnaco Common Stock covered by such registration statement are sold or
disposed of and (iii) such time as all such shares of Warnaco Common Stock are
freely tradeable.
 
     Non-Competition. Each of CEP II and Arnold H. Simon has also covenanted
that, subject to certain limited exceptions, commencing on October 14, 1997 and
until October 14, 1999, it will not, and, as to Mr. Simon, he will cause his
affiliates not to, in North America, South America and Central America, directly
or indirectly, invest in (other than a passive equity investment constituting no
more than 5% of the equity of the subject company), engage in, become
financially interested in, or be employed by, whether as an employee,
consultant, partner, principal, agent, representative or stockholder or in any
other corporate or representative capacity, if it involves engaging in, or
rendering services that are integral to the business of or advice pertaining to,
any lines of business Warnaco was actively conducting on September 25, 1997, or
October 14, 1997, except in connection with the written consent of Warnaco, or,
in the case of CEP II, in connection with its investments existing on September
25, 1997, nor will CEP II or Mr. Simon solicit any business of the type
conducted by Designer Holdings from any customer of Designer Holdings or hire
any employee of Designer Holdings or any of its subsidiaries.
 
     Each Seller has further covenanted to hold in strict confidence all data
and information relating to the business of Designer Holdings and its
subsidiaries obtained in the course of its ownership of shares or participation
in the management of Designer Holdings or any of its subsidiaries or otherwise
which is either non-public, confidential or proprietary in nature and that it
will, subject to any requirement of law or tribunal order, keep such information
confidential and will not, without the prior written consent of Warnaco,
disclosed any such information to any person.
 
     Waiver of Dividend. The Sellers have irrevocably waived their right, with
respect to the Exchange Shares, to receive any dividend declared by Warnaco's
Board that is payable to holders of record of Warnaco Common Stock as of a
record date subsequent to October 14, 1997, and prior to the Effective Time.
 
                                  THE MEETINGS
 
     This Joint Proxy Statement/Prospectus is furnished in connection with the
solicitation of proxies (i) from the holders of Warnaco Common Stock by the
Warnaco Board for use at the Warnaco Meeting and (ii) from the holders of
Designer Holdings Common Stock by the Designer Holdings Board for use at the
Designer Holdings Meeting. This Joint Proxy Statement/Prospectus and
accompanying form of proxy are first being mailed to the respective stockholders
of Warnaco and Designer Holdings on or about November 14, 1997.
 
TIMES AND PLACES; PURPOSES
 
     The Warnaco Meeting will be held at The Four Seasons Hotel, 57 East 57th
Street, New York, New York 10022, on December 12, 1997, starting at 10:00 a.m.,
New York time. At the Warnaco Meeting, the stockholders of Warnaco will be asked
to consider and vote upon (i) the issuance of shares of Warnaco Common Stock in
the Merger, the Exchange and upon any conversions of the Convertible Debentures
(the 'Warnaco Merger Proposal'), and (ii) if necessary, to approve any
adjournment of the Warnaco Meeting without further notice except by announcement
at the meeting being adjourned.
 
     The rules of the NYSE require that a listed company's stockholders approve
the issuance of securities in any transaction or series of transactions in which
the aggregate number of shares to be issued would exceed 20% of the total shares
issued and outstanding prior to such issuance. The aggregate number of shares of
Warnaco Common Stock to be issued in the Exchange, the Merger and upon any
conversions of the Convertible Debentures would exceed 20% of
 
                                       61

the outstanding shares of Warnaco Common Stock prior to the Exchange, which is
why we are seeking the approval of the Warnaco stockholders. However, failure to
obtain the requisite stockholder approval of the Warnaco Merger Proposal will
not have any effect on the Exchange, which has already occurred.
 
     The Designer Holdings Meeting will be held at The Four Seasons Hotel, 57
East 57th Street, New York, New York 10022, on December 12, 1997, starting at
9:30 a.m., New York time. At the Designer Holdings Meeting, the stockholders of
Designer Holdings will be asked to consider and vote upon (i) the approval and
adoption of the Merger Agreement and the Merger (the 'Designer Holdings Merger
Proposal' and, together with the Warnaco Merger Proposal, the 'Merger
Proposals'), and (ii) if necessary, to approve any adjournment of the Designer
Holdings Meeting without further notice except by announcement at the meeting
being adjourned.
 
VOTING RIGHTS; VOTES REQUIRED FOR APPROVAL
 
     Warnaco. The Warnaco Board has fixed the close of business on October 14,
1997 as the record date (the 'Warnaco Record Date') for Warnaco stockholders
entitled to notice of and to vote at the Warnaco Meeting.
 
     The only outstanding voting securities of Warnaco are the shares of Warnaco
Common Stock. Only holders of record of the shares of Warnaco Common Stock on
the Warnaco Record Date are entitled to notice of and to vote at the Warnaco
Meeting. Under the DGCL and the Warnaco Charter, each share of Warnaco Common
Stock is entitled to one vote on all matters submitted to Warnaco stockholders.
 
     On the Warnaco Record Date, there were 57,369,721 shares of Warnaco Common
Stock outstanding and entitled to vote at the Warnaco Meeting, held by
approximately 154 stockholders of record.
 
     The presence in person or by proxy of the holders of a majority of the
shares of Warnaco Common Stock issued and outstanding and entitled to vote
thereat is necessary to constitute a quorum at the Warnaco Meeting. The
affirmative vote of a majority of the votes represented by the shares of Warnaco
Common Stock present at the Warnaco Meeting, in person or by proxy, and entitled
to vote thereat, is required to approve the Warnaco Merger Proposal.
 
     The directors and officers of Warnaco beneficially own approximately 17% of
the outstanding Warnaco Common Stock, of which 14.7% is owned beneficially by
Mrs. Wachner. Mrs. Wachner has agreed to vote all such shares that are
outstanding on the Warnaco Record Date in favor of the Warnaco Merger Proposal.
 
     Designer Holdings. The Designer Holdings Board has fixed the close of
business on October 14, 1997 (the 'Designer Holdings Record Date') as the record
date for Designer Holdings stockholders entitled to notice of and to vote at the
Designer Holdings Meeting.
 
     The only class of Designer Holdings capital stock entitled to notice of and
to vote at the Designer Holdings Meeting is the Designer Holdings Common Stock.
Only holders of record of shares of Designer Holdings Common Stock on the
Designer Holdings Record Date are entitled to notice of and to vote at the
Designer Holdings Meeting. Each holder of record, as of the Designer Holdings
Record Date, of Designer Holdings Common Stock is entitled to cast one vote per
share.
 
     On the Designer Holdings Record Date, there were 32,159,344 shares of
Designer Holdings Common Stock outstanding and entitled to vote at the Designer
Holdings Meeting, held by approximately 131 stockholders of record. The
directors and officers of Designer Holdings beneficially own approximately 0.8%
of the outstanding Designer Holdings Common Stock.
 
     The presence, in person or by proxy, of the holders of a majority of the
outstanding shares of Designer Holdings Common Stock entitled to vote is
necessary to constitute a quorum at the Designer Holdings Meeting. The
affirmative vote, in person or by proxy, of the holders of a
major-
 
                                       62
 


<PAGE>

<PAGE>
ity of the shares of Designer Holdings Common Stock outstanding on the Designer
Holdings Record Date is required to approve and adopt the Designer Holdings
Merger Proposal.
 
     WARNACO OWNS APPROXIMATELY 51.3% OF THE ISSUED AND OUTSTANDING DESIGNER
HOLDINGS COMMON STOCK AS OF THE DESIGNER HOLDINGS RECORD DATE. WARNACO HAS
AGREED TO VOTE ALL OF SUCH SHARES IN FAVOR OF THE DESIGNER HOLDINGS MERGER
PROPOSAL. ACCORDINGLY, NO ACTION BY ANY OTHER DESIGNER HOLDINGS STOCKHOLDER IS
REQUIRED TO APPROVE THE MERGER.
 
PROXIES
 
     All shares of Warnaco Common Stock and of Designer Holdings Common Stock
represented by properly executed proxies received prior to or at the respective
Warnaco Meeting or Designer Holdings Meeting, as the case may be, and not
revoked, will be voted in accordance with the instructions indicated in such
proxies. If no instructions are indicated on a properly executed returned proxy,
such proxies will be voted FOR the approval of the Warnaco Merger Proposal or
the Designer Holdings Merger Proposal, as the case may be.
 
     Abstentions may be specified on the Merger Proposals. A properly executed
proxy marked 'ABSTAIN' with respect to any proposal will be counted as present
for purposes of determining whether there is a quorum and for purposes of
determining the aggregate voting power and number of shares represented and
entitled to vote at the applicable Meeting with respect to the indicated
proposal. Accordingly, since the affirmative votes described above are required
for approval of the Designer Holdings Merger Proposal and the Warnaco Merger
Proposal, a proxy marked 'ABSTAIN' with respect to any such proposal will have
the effect of a vote against such proposal. In addition, the failure of a
Designer Holdings stockholder to return a proxy will have the effect of vote
against the Designer Holdings Merger Proposal.
 
     Under NYSE rules, brokers who hold shares in street name for customers have
the authority to vote on certain 'routine' proposals when they have not received
instructions from beneficial owners. Under NYSE rules, such brokers are
precluded from exercising their voting discretion with respect to the approval
and adoption of non-routine matters such as the Merger and the issuance of
shares of Warnaco Common Stock in the Merger, the Exchange and upon any
conversions of the Convertible Debentures and thus, absent specific instructions
from the beneficial owner of such shares, brokers are not empowered to vote such
shares with respect to the approval and adoption of the Warnaco Merger Proposal
or the Designer Holdings Merger Proposal (i.e., 'broker non-votes'). Since the
affirmative votes described above are required for approval of the Designer
Holdings Merger Proposal and the Warnaco Merger Proposal, a 'broker non-vote'
with respect to either such proposal will have the effect of a vote against such
proposal. Because Warnaco will vote 51.3% of the outstanding shares of Designer
Holdings Common Stock in favor of the Designer Holdings Merger Proposal, any
such broker non-vote will be of no consequence with respect to obtaining the
Designer Holdings Stockholder Approval.
 
     A stockholder may revoke his or her proxy at any time prior to its use by
delivering to the Secretary of Warnaco or Designer Holdings, as the case may be,
a signed notice of revocation or a later-dated signed proxy or by attending the
applicable Meeting and voting in person. Attendance at the Warnaco Meeting or
the Designer Holdings Meeting will not in itself constitute the revocation of a
proxy.
 
     It is the policy of Warnaco and Designer Holdings to keep confidential
proxy cards, ballots and voting tabulations that identify individual
stockholders, except where disclosure is mandated by law and in other limited
circumstances.
 
     The cost of solicitation of proxies will be paid by Warnaco for Warnaco
proxies and by Designer Holdings for Designer Holdings proxies. In addition to
solicitation by mail, arrangements will be made with brokerage houses and other
custodians, nominees and fiduciaries to send the proxy materials to beneficial
owners; and Warnaco or Designer Holdings, as the case may be, will, upon
request, reimburse such brokerage houses and custodians for their reasonable
expenses in so
 
                                       63

doing. Warnaco has retained MacKenzie Partners, Inc. to aid in the solicitation
of proxies and to verify certain records related to the solicitations. MacKenzie
Partners, Inc. will receive customary fees, and expense reimbursement, for such
services. To the extent necessary in order to ensure sufficient representation
at its Meeting, Warnaco or Designer Holdings or its representatives may request
by telephone or telegram the return of proxy cards. The extent to which this
will be necessary depends entirely upon how promptly proxy cards are returned.
Stockholders are urged to send in their proxies without delay.
 
     STOCKHOLDERS SHOULD NOT SEND IN ANY STOCK CERTIFICATES WITH THEIR PROXY
CARDS. A TRANSMITTAL FORM WITH INSTRUCTIONS FOR THE SURRENDER OF STOCK
CERTIFICATES FOR DESIGNER HOLDINGS COMMON STOCK WILL BE MAILED BY WARNACO TO
FORMER DESIGNER HOLDINGS STOCKHOLDERS AS SOON AS PRACTICABLE AFTER THE
CONSUMMATION OF THE MERGER.
 
OTHER BUSINESS; ADJOURNMENTS
 
     The Warnaco Board and the Designer Holdings Board are not currently aware
of any business to be acted upon at their respective Meetings other than as
described herein. If, however, other matters are properly brought before either
Meeting, or any adjournments or postponements thereof, the persons appointed as
proxies will have discretion to vote or act thereon according to their best
judgment. Adjournments may be made for the purpose of, among other things,
soliciting additional proxies. Any adjournment may be made from time to time by
approval of the holders of a majority of the shares present in person or by
proxy at the Meeting (whether or not a quorum exists) without further notice
other than by an announcement made at the Meeting. Neither Warnaco nor Designer
Holdings currently intends to seek an adjournment or postponement of its
respective Meeting. Any postponements or adjournments of a special meeting for
the purpose of soliciting additional proxies will allow stockholders who have
already tendered their proxies to revoke such proxies at any time prior to the
use of the related proxy.

                        COMPARISON OF STOCKHOLDER RIGHTS
 
GENERAL
 
     The rights of Warnaco stockholders are currently governed by the DGCL and
the amended and restated certificate of incorporation and bylaws of Warnaco (the
'Warnaco Charter' and the 'Warnaco Bylaws', respectively). The rights of
Designer Holdings stockholders are currently governed by the DGCL and the
restated certificate of incorporation and bylaws of Designer Holdings (the
'Designer Holdings Charter' and the 'Designer Holdings Bylaws', respectively).
Accordingly, upon consummation of the Merger, the rights of Warnaco stockholders
and of Designer Holdings stockholders who become Warnaco stockholders in the
Merger will be governed by the DGCL, the Warnaco Charter and the Warnaco Bylaws.
The following is a summary of the principal differences between the current
rights of Designer Holdings stockholders and those of Warnaco stockholders
following the Merger.
 
     The following discussions are qualified by reference to the DGCL, the
Warnaco Charter, the Warnaco Bylaws, the Designer Holdings Charter and the
Designer Holdings Bylaws. Copies of the Warnaco Charter, the Warnaco Bylaws, the
Designer Holdings Charter and the Designer Holdings Bylaws are incorporated by
reference herein and will be sent to holders of shares of Warnaco Common Stock
and Designer Holdings Common Stock upon request. See 'Where You Can Find More
Information'.
 
COMPARISON OF CURRENT DESIGNER HOLDINGS STOCKHOLDER RIGHTS AND RIGHTS OF WARNACO
STOCKHOLDERS FOLLOWING THE MERGER
 
     Neither the Warnaco Charter nor the Warnaco Bylaws are being amended in
connection with the Merger.
 
     The rights of Designer Holdings stockholders under the DGCL and the
Designer Holdings Charter and Designer Holdings Bylaws prior to the Merger are
substantially the same as the rights of Warnaco stockholders (including Designer
Holdings stockholders who become Warnaco stockholders as a result of the Merger)
under the DGCL and the Warnaco Charter and Warnaco Bylaws, with the following
principal exceptions.
 
     Authorized Capital Stock. The authorized capital stock of Designer Holdings
consists of 75,000,000 shares of Common Stock, 1,300,000 shares of Non-voting
Common Stock (which are convertible at any time into an equal number of shares
of Common Stock), and 15,000,000 shares of preferred stock, par value $0.01 per
share. The authorized capital of Warnaco is set forth under 'Description of
Warnaco Capital Stock -- Authorized Capital Stock'.
 
     Board of Directors. The Designer Holdings Charter provides that the number
of directors will be such number as determined by the Designer Holdings Board,
to be classified into 3 classes, as nearly equal in number as possible, with
directors serving staggered three-year terms. The Designer Holdings Bylaws
provide that the number of directors shall be not less than 5 nor more than 15.
Warnaco's Board currently consists of seven directors. The Warnaco Charter
provides that the number of directors will be such number as determined by the
Warnaco Board, to be classified into 3 classes, as nearly equal in number as
possible, with directors serving staggered three-year terms. The Warnaco Bylaws
provide that the number of directors shall be not less than 5 nor more than 12.
 
     Filling Vacancies on the Board. The Designer Holdings Bylaws provide that
vacancies resulting from an increase in the authorized number of directors may
be filled by a majority of the directors provided that a quorum is present. A
vacancy occurring on the Designer Holdings Board for any other reason may be
filled by the majority of directors, whether a quorum exists or not. The Warnaco
Charter and Bylaws provide that any vacancy on the Warnaco Board may be filled
by a majority of the directors, whether a quorum exists or not.
 
                                       65
 


<PAGE>

<PAGE>
     Stockholder Action by Written Consent. Neither the Designer Holdings
Charter nor the Warnaco Charter permits any action required or permitted to be
taken by a vote of the holders of the respective company's common stock to be
taken by written consent. The Designer Holdings Charter permits Designer
Holdings preferred stockholders to act by written consent whenever any action is
required or permitted to be taken by a vote at a stockholder meeting only if
such written consent is signed by at least the minimum number of preferred
stockholders necessary to take such action at a meeting at which all shares of
preferred stock entitled to vote were present.
 
     Amendment of Corporate Charter and Bylaws. Any amendment to the Designer
Holdings Charter requires approval by a majority of the Designer Holdings Board
and the holders of the majority of voting power of issued and outstanding stock.
Any amendment to the Designer Holdings Bylaws requires approval by a majority of
the Designer Holdings Board or by holders of 80% of the outstanding stock
entitled to vote. Any amendment to the provisions of the Warnaco Charter
concerning the right of the Warnaco Board to amend the Warnaco By-laws, the
classified board, the prohibition against action by written consent, the right
to call a special meeting, the removal of directors, exculpation of directors
and the supermajority voting requires the affirmative vote of the holders of at
least two-thirds of the outstanding shares of Warnaco Common Stock. Any
amendment to the Warnaco Bylaws requires approval of the holders of the majority
of the outstanding stock entitled to vote or by the majority of the Board.
 
     Voting Rights. The Designer Holdings Common Stock is the only class of
Designer Holdings capital stock entitled to vote generally on all matters
submitted to Designer Holdings stockholders, including the election of directors
and the Merger and other transactions contemplated by the Merger Agreement. Each
share of Designer Holdings Common Stock is entitled to one vote on all matters
submitted to Designer Holdings stockholders. The Warnaco Common Stock is
entitled to vote generally on all matters submitted to the Warnaco stockholders
for a vote, with each share entitled to one vote.
 
                      DESCRIPTION OF WARNACO CAPITAL STOCK
 
     The summary of the terms of the capital stock of Warnaco set forth below is
qualified by reference to the Warnaco Charter and Warnaco Bylaws. Copies of the
Warnaco Charter and Warnaco Bylaws are incorporated by reference herein and will
be sent to holders of shares of Warnaco Common Stock and Designer Holdings
Common Stock upon request. See 'Where You Can Find More Information'.
 
AUTHORIZED CAPITAL STOCK
 
     Under the Warnaco Charter, Warnaco's authorized capital stock consists of
130,000,000 shares of Warnaco Common Stock, par value $0.01 per share, and
10,000,000 shares of preferred stock, par value $0.01 per share.
 
WARNACO COMMON STOCK
 
     As of October 14, 1997, 57,369,721 shares of Warnaco Common Stock were
issued and outstanding. In addition, 807,963 shares of Warnaco Common Stock were
held in the treasury of Warnaco, and 8,441,164 shares of Warnaco Common Stock
were reserved for issuance pursuant to the Employee Stock Plan, the 1993 Stock
Plan for Non-Employee Directors and the Amended and Restated 1993 Stock Plan.
 
     The holders of Warnaco Common Stock are entitled to receive ratably, from
funds legally available for the payment thereof, dividends when and as declared
by resolution of the Warnaco Board, subject to any preferential dividend rights
which may be granted to holders of any preferred stock authorized and issued by
the Warnaco Board. In the event of liquidation, each share of Warnaco Common
Stock is entitled to share pro rata in any distribution of Warnaco's assets
after payment or providing for the payment of liabilities and any liquidation
preference of any
 
                                       66
 


<PAGE>

<PAGE>
preferred stock authorized and issued by the Warnaco Board. Each holder of
Warnaco Common Stock is entitled to one vote for each share of Warnaco Common
Stock held of record on the applicable record date on all matters submitted to a
vote of stockholders, including the election of directors.
 
     Holders of Warnaco Common Stock have no cumulative voting rights or
preemptive rights to purchase or subscribe for any stock or other securities,
and there are no conversion rights or redemption rights or sinking fund
provisions with respect to Warnaco Common Stock. The outstanding shares of
Warnaco Common Stock are, and the shares of Warnaco Common Stock issued pursuant
to the Merger will be, duly authorized, validly issued, fully paid and
nonassessable.
 
WARNACO PREFERRED STOCK
 
     As of September 22, 1997, no shares of preferred stock were issued or
outstanding. Under the Warnaco Charter, the Warnaco Board has the authority,
without further stockholder approval to create one or more series of preferred
stock, to issue shares of preferred stock in such series up to the maximum
number of shares of the relevant class of preferred stock authorized, and to
determine the preferences, rights, privileges and restrictions of any such
series, including the dividend rights, voting rights, rights and terms of
redemption, liquidation preferences, the number of shares constituting any such
series and the designation of such series. Pursuant to this authority, the
Warnaco Board could create and issue a series of preferred stock with rights,
privileges or restrictions, and adopt a stockholder rights plan, having the
effect of discriminating against an existing or prospective holder of such
securities as a result of such security holder beneficially owning or commencing
a tender offer for a substantial amount of Warnaco Common Stock. One of the
effects of authorized but unissued and unreserved shares of capital stock may be
to render more difficult or discourage an attempt by a potential acquiror to
obtain control of Warnaco by means of a merger, tender offer, proxy contest or
otherwise, and thereby protect the continuity of Warnaco's management. The
issuance of such shares of capital stock may have the effect of delaying,
deferring or preventing a change in control of Warnaco without any further
action by the stockholders of Warnaco. Warnaco has no present intention to adopt
a shareholder rights plan, but could do so without shareholder approval at any
future time.
 
TRANSFER AGENT AND REGISTRAR
 
     ChaseMellon Shareholder Services, L.L.C. is the transfer agent and
registrar for the Warnaco Common Stock.
 
STOCK EXCHANGE LISTING; DELISTING AND DEREGISTRATION OF DESIGNER HOLDINGS COMMON
STOCK
 
     It is a condition to the Merger that Warnaco shall use its reasonable best
efforts to cause the shares of Warnaco Common Stock issuable in the Merger to be
approved for listing on the NYSE on or prior to the Effective Time, subject to
official notice of issuance. If the Merger is consummated, Designer Holdings
Common Stock will cease to be listed on the NYSE.
 
TREATMENT OF TOPRS
 
     Under the terms of the Merger Agreement, Warnaco and Designer Holdings have
agreed to take such steps as are necessary to ensure that the holders of the
TOPrS will, after the Effective Time, have the right to convert the TOPrS into
shares of Warnaco Common Stock on the terms and conditions set forth in the
indenture relating to the Convertible Debentures. Warnaco currently expects that
following the consummation of the Merger, Warnaco will enter into a limited
guarantee of Designer Holdings' obligations to the holders of the TOPrS and an
indenture supplemental to such indenture pursuant to which it will become
jointly and severally liable with Designer Holdings for the Convertible
Debentures.

WARNACO GROUP, INC., a Delaware corporation ('Parent'), WAC ACQUISITION
CORPORATION, a Delaware corporation and a wholly owned subsidiary of Parent
('Sub'), and DESIGNER HOLDINGS LTD., a Delaware corporation (the 'Company').
 
     WHEREAS, the respective Boards of Directors of Parent, Sub and the Company
have determined that the merger of Sub (or, at the election of Parent as set
forth in Section 1.01, a direct wholly owned subsidiary of Parent other than
Sub) with and into the Company (the 'Merger'), upon the terms and subject to the
conditions set forth in this Agreement, would be fair to and in the best
interests of their respective stockholders, and such Boards of Directors have
approved such Merger, pursuant to which (a) each share of Common Stock, each
having a par value of one cent ($0.01) of the Company ('Company Common Stock')
issued and outstanding immediately prior to the Effective Time of the Merger (as
defined in Section 1.03) will be converted into the right to receive shares of
Class A Common Stock, par value $0.01 per share, of Parent ('Parent Class A
Common Stock'), other than shares of Company Common Stock owned, directly or
indirectly, by the Company or any wholly owned subsidiary (as defined in Section
8.03) of the Company or held by the Company as treasury shares or owned by
Parent, Sub or any other wholly owned subsidiary of Parent.
 
     WHEREAS, the affirmative vote of a majority of the outstanding shares of
the Company Common Stock is required for the approval and adoption of the Merger
and this Merger Agreement (the 'Company Stockholder Approval');
 
     WHEREAS, to the extent required in accordance with applicable regulations
of the New York Stock Exchange (the 'NYSE'), the issuance of shares of Parent
Class A Common Stock in connection with the transactions contemplated hereby
requires the affirmative vote of a majority of shares present in person or
represented by proxy and entitled to vote thereon at a meeting of the holders of
Parent Class A Common Stock;
 
     WHEREAS, as a condition to their willingness to enter into this Agreement,
Parent and Sub have required that New Rio, L.L.C. (the 'Stockholder') and the
members of Stockholder signatory thereto (the 'Members') (collectively, the
'Sellers') enter into, and the Sellers have agreed to enter into, the Stock
Exchange Agreement with Parent dated of even date herewith (as amended from time
to time in accordance with its terms, the 'Stock Exchange Agreement') relating
to the exchange by the Stockholder (the 'Exchange') of all of the outstanding
shares of Company Common Stock owned by it (the 'Stockholder Shares'), which
represent a majority of the outstanding shares of Company Common Stock, in
exchange for shares of Parent Class A Common Stock on the terms set forth in the
Stock Exchange Agreement, and, in order to induce Parent and Sub to enter into
this Agreement, the Board of the Directors of the Company has approved the
entering into by Parent, the Members and the Stockholder of the Stock Exchange
Agreement and the consummation of the transactions contemplated thereby;
 
     WHEREAS, Parent, Sub and the Company desire to make certain
representations, warranties, covenants and agreements in connection with the
Merger and also to prescribe various conditions to the Merger; and
 
     WHEREAS, for Federal income tax purposes, it is intended that the Exchange
and the Merger qualify as a reorganization under the provisions of Section 368
of the Internal Revenue Code of 1986, as amended (the 'Code').
 
     NOW, THEREFORE, in consideration of the representations, warranties,
covenants and agreements contained in this Agreement, the parties agree as

recordings required under the DGCL. The Merger shall become effective at such
time as the Certificate of Merger shall have been duly filed with the Secretary
of State of the State of Delaware, or at such later time as is agreed by Parent
and the Company and specified in the Certificate of Merger (the time the Merger
becomes effective being the 'Effective Time of the Merger').

incorporation shall be amended as follows: (i) Article Fourth shall be amended
to read in its entirety as follows: 'The total number of shares of stock which
the Corporation shall have the authority to issue is 1,000 shares, each having a
par value of one cent ($0.01)'; (ii) paragraph (6) of Article Fifth shall be
deleted in its entirety; and (iii) the second paragraph of Article Sixth shall

     SECTION 1.06. Directors. The directors of Sub at the Effective Time of the

                                   ARTICLE II

                EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE
                            CONSTITUENT CORPORATIONS
 
     SECTION 2.01. Effect on Capital Stock. As of the Effective Time of the
Merger, by virtue of the Merger and without any action on the part of the holder
of any shares of Company Common Stock or any shares of capital stock of Sub:
 
                                      A-2
 
<PAGE>

<PAGE>
          (a) Common Stock of Sub. Each share of common stock, par value $0.01
     per share, of Sub issued and outstanding immediately prior to the Effective
     Time of the Merger shall be converted into one share of the common stock of
     the Surviving Corporation and shall constitute the only issued and
     outstanding capital stock of the Surviving Corporation.
 
          (b) Cancellation of Treasury Stock and Parent-Owned Company Common
     Stock. Each share of Company Common Stock that is owned by the Company or
     held by the Company as treasury shares or owned by any direct or indirect
     wholly owned subsidiary of the Company, and each share of Company Common
     Stock that is owned by Parent, Sub or any other direct or indirect wholly
     owned subsidiary of Parent shall automatically be cancelled and retired and
     shall cease to exist, and no Parent Class A Common Stock or other
     consideration shall be delivered or deliverable in exchange therefor.
 
          (c) Conversion of Company Common Stock. Except as otherwise provided
     herein, each issued and outstanding share of Company Common Stock shall be
     converted into the right to receive from Parent .324 of a fully paid and
     nonassessable share of Parent Class A Common Stock (the 'Exchange Ratio');
     provided, however, that, in any event, if between the date of this
     Agreement and the Effective Time of the Merger the outstanding shares of
     Parent Class A Common Stock shall have been changed into a different number
     of shares or a different class, by reason of any stock dividend,
     subdivision, reclassification, recapitalization, split, combination or
     exchange of shares, the Exchange Ratio shall be correspondingly adjusted to
     reflect such stock dividend, subdivision, reclassification,
     recapitalization, split, combination or exchange of shares.
 
          (d) Treatment of Trust Preferred Securities; Convertible Debentures.
     Prior to or concurrently with the Closing, Parent and the Company shall
     take such steps as are necessary to ensure the resignation of Arnold H.
     Simon and Merril M. Halpern as Trustees of Designer Finance Trust. In
     addition, Parent and the Company shall take such actions as may be
     necessary to ensure compliance by the Company and Parent with Section 1304
     of the Indenture dated as of November 1, 1996 (the 'Indenture'), relating
     to $123,711,350 of 6% Convertible Debentures Due 2016 (the 'Convertible
     Debentures'), and shall take such steps as are necessary to ensure that
     holders of the Convertible Debentures shall, after the Effective Time of
     the Merger, have the right to convert such securities into shares of Parent
     Class A Common Stock on the terms and conditions set forth in the
     Indenture.
 
          (e) Cancellation and Retirement of Company Common Stock. From and
     after the Effective Time of the Merger, all shares of Company Common Stock
     issued and outstanding immediately prior to the Effective Time of the
     Merger shall no longer be outstanding and shall automatically be cancelled
     and retired and shall cease to exist, and each holder of a certificate
     which immediately prior to the Effective Time of the Merger represented
     shares of Company Common Stock ('Company Share Certificate') shall cease to
     have any rights with respect thereto, except the right to receive the
     consideration to be issued to holders of Company Common Stock in the Merger
     pursuant to Section 2.01(c) (the 'Merger Consideration'), any cash in lieu
     of fractional shares of Parent Class A Common Stock to be paid in
     consideration therefor upon surrender of such certificate in accordance
     with Section 2.04 and any dividends payable pursuant to Section 2.03(f).
 
     SECTION 2.02. Stock Plans. As soon as practicable following the date of
this Agreement, but in any event prior to the consummation of the Exchange, the
Board of Directors of the Company (or, if appropriate, any committee
administering the Stock Plans (as defined below)) shall adopt such resolutions
or take such other actions as may be required to effect the following (it being
understood that if the following is not permitted pursuant to the terms of the
Stock Plans, the Company shall use its reasonable best efforts to obtain any
consents or take any other action necessary in order to effect the following):
 
          (a) The Company shall adjust the terms of all outstanding employee or
     director stock options to purchase shares of Company Common Stock ('Company
     Stock Options') granted under any stock option or stock purchase plan,
     program or arrangement of the Company, including the Designer Holdings Ltd.
     1996 Stock Option and Incentive Plan and the 1996 Outside Director Stock
     Option Plan (collectively, the 'Stock Plans'), whether or not then
     exercisable, to provide that, at the Effective Time of the Merger, each
     Company Stock Option outstanding immediately prior to
 
                                      A-3
 
<PAGE>

<PAGE>
     the Effective Time of the Merger shall be cancelled to the extent that the
     exercise price of such Company Stock Option equals or exceeds $11 per
     share. With respect to any Company Stock Option not cancelled pursuant to
     the preceding sentence, such Company Stock Option shall be deemed to
     constitute an option (each, a 'Parent Stock Option') to acquire, on the
     same terms and conditions as were applicable under such Company Stock
     Option, the number of shares of Parent Class A Common Stock equal to the
     product of (1) the number of shares of Company Common Stock issuable upon
     exercise of such Company Stock Option and (2) the Exchange Ratio, at a
     price per share equal to (1) the aggregate exercise price for the shares of
     Company Common Stock otherwise purchasable pursuant to such Company Stock
     Option divided by (2) the number of shares of Parent Class A Common Stock
     issuable per share of Company Common Stock upon exercise of such Company
     Stock Option as set forth above; provided, however, that, after aggregating
     all the shares of a holder subject to Company Stock Options, any fractional
     share of Parent Class A Common Stock resulting from such calculation for
     such holder shall be rounded down to the nearest whole share; and provided,
     further, that in the case of any Company Stock Option to which Sections 422
     and 423 of the Code applies by reason of its qualification under any of
     Sections 422-424 of the Code ('qualified stock options'), Parent and the
     Company shall use their reasonable best efforts to cause the option price,
     the number of shares purchasable pursuant to such option, the terms and
     conditions of exercise of such option and such other terms and conditions
     of such option to be determined in order to comply with Section 424(a) of
     the Code; and
 
          (b) Except as provided herein or as otherwise agreed to by the
     parties, the Stock Plans and any other plan, program or arrangement
     providing for the issuance or grant of any other interest in respect of the
     capital stock of the Company or any subsidiary shall terminate as of the
     Effective Time of the Merger. After the Merger, each Parent Stock Option
     shall be exercisable upon the same terms and conditions (including
     conditions relating to vesting and exercisability) as were applicable to
     the Company Stock Options immediately prior to the Merger and the Company
     shall use its reasonable best efforts to ensure that following the
     Effective Time of the Merger no holder of a Company Stock Option nor any
     participant in any Stock Plan shall have any right thereunder to acquire
     equity securities of the Company or the Surviving Corporation.
 
     SECTION 2.03. Exchange of Certificates. (a) Prior to the Effective Time of
the Merger, Parent shall appoint an agent (the 'Exchange Agent') for the purpose
of exchanging Company Share Certificates for the Merger Consideration.
Immediately following the Effective Time of the Merger, Parent shall deposit
with the Exchange Agent, for the benefit of the holders of Company Share
Certificates, certificates representing the Parent Common Stock issuable
pursuant to Section 2.01 in exchange for Company Share Certificates. Promptly
after the Effective Time of the Merger Parent will send, or will cause the
Exchange Agent to send, to each holder of Company Share Certificates at the
Effective Time of the Merger (i) a letter of transmittal for use in such
exchange which shall specify that delivery of the Merger Consideration shall be
effected, and risk of loss and title to the certificates representing Parent
Class A Common Stock and Company Share Certificates shall pass, only upon proper
delivery of the Company Share Certificates to the Exchange Agent and (ii)
instructions for use in effecting the surrender of such Company Share
Certificates in exchange for the certificates representing Parent Class A Common
Stock.
 
     (b) Each holder of Company Share Certificates that have been converted into
a right to receive the Merger Consideration, upon surrender to the Exchange
Agent of such Company Share Certificates, together with a properly completed
letter of transmittal covering such Company Share Certificates, will be entitled
to receive the Merger Consideration payable in respect of such Company Share
Certificates and any dividends payable pursuant to Section 2.03(f). Until so
surrendered, each such Company Share Certificate shall, after the Effective
Time, represent for all purposes only the right to receive the Merger
Consideration, any cash payable in lieu of fractional shares pursuant to Section
2.04 and any dividends payable pursuant to Section 2.03(f).
 
     (c) If any portion of the Merger Consideration is to be paid to a person
other than the registered holder of a Company Share Certificate, it shall be a
condition to such payment that such Company Share Certificate so surrendered
shall be properly endorsed or otherwise be in proper form for transfer and that
the person requesting such payment shall pay to the Exchange Agent any transfer
or other
 
                                      A-4
 
<PAGE>

<PAGE>
taxes required by reason of the issuance of shares of Parent Class A Common
Stock in exchange for the Company Share Certificate so surrendered or establish
to the satisfaction of the Exchange Agent that such tax has been paid or is not
applicable.
 
     (d) After the Effective Time, there shall be no further registration of
transfers of shares of Company Common Stock. If, after the Effective Time,
Company Share Certificates are presented to the Surviving Corporation, they
shall be cancelled and exchanged for the Merger Consideration provided for, and
in accordance with the procedures set forth, in this Article II.
 
     (e) Any portion of the Merger Consideration made available to the Exchange
Agent pursuant to Section 2.03(a) that remains unclaimed by the holders of
Company Share Certificates six months after the Effective Time of the Merger
shall be returned to Parent, upon demand, and any such holder who has not
exchanged his Company Share Certificates for the Merger Consideration in
accordance with this Section 2.03 prior to that time shall thereafter look only
to Parent for payment of the Merger Consideration, any cash payable in lieu of
fractional shares pursuant to Section 2.04 and any dividends payable pursuant to
Section 2.03(f) in respect of his shares. Notwithstanding the foregoing, Parent
shall not be liable to any holder of Company Share Certificates for any amount
paid to a public official pursuant to applicable abandoned property laws. Any
amounts remaining unclaimed by holders of Company Share Certificates seven years
after the Effective Time of the Merger (or such earlier date immediately prior
to such time as such amounts would otherwise escheat to or become property of
any governmental entity) shall, to the extent permitted by applicable law,
become the property of Parent free and clear of any claims or interest of any
person previously entitled thereto.
 
     (f) No dividends or other distributions with respect to Parent Class A
Common Stock issued in the Merger shall be paid to the holder of any
unsurrendered Company Share Certificates until such certificates are surrendered
as provided in this Section 2.03. Subject to the effect of applicable laws,
following the surrender of such certificates, there shall be paid, without
interest, to the record holder of the Parent Class A Common Stock issued in
exchange therefor at the time of such surrender, the amount of dividends or
other distributions with a record date after the Effective Time of the Merger
payable prior to or on the date of such surrender with respect to such whole
shares of Parent Class A Common Stock and not previously paid, less the amount
of any withholding taxes (if any) which may be required thereon.
 
     SECTION 2.04. Fractional Shares. (a) No fractional shares of Parent Class A
Common Stock shall be issued in the Merger, but in lieu thereof each holder of
Company Share Certificates otherwise entitled to a fractional share of Parent
Class A Common Stock will be entitled to receive, from the Exchange Agent in
accordance with the provisions of this Section 2.04, a cash payment in lieu of
such fractional shares of Parent Class A Common Stock representing such holder's
proportionate interest, if any, in the net proceeds from the sale by the
Exchange Agent in one or more transactions of (i) the number of shares of Parent
Class A Common Stock delivered to the Exchange Agent by Parent pursuant to
Section 2.03(a) over (ii) the aggregate number of whole shares of Parent Class A
Common Stock to be distributed to the holders of the Company Share Certificates
pursuant to Section 2.03(b) (such excess being herein called the 'Excess
Shares'). As soon as practicable after the Effective Time of the Merger, the
Exchange Agent, as agent for the holders of the Company Share Certificates,
shall sell the Excess Shares at then prevailing prices on the NYSE all in the
manner provided in the following paragraph.
 
     (b) The sale of the Excess Shares by the Exchange Agent shall be executed
on the NYSE through one or more member firms of the NYSE and shall be executed
in round lots to the extent practicable. The proceeds from such sale or sales
available for distribution to the holders of Company Share Certificates shall be
reduced by the compensation payable to the Exchange Agent and the expenses
incurred by the Exchange Agent, in each case, in connection with such sale or
sales of the Excess Shares, including all related commissions, transfer taxes
and other out-of-pocket transaction costs. Until the net proceeds of such sale
or sales have been distributed to the holders of Company Share Certificates, the
Exchange Agent shall hold such net proceeds in trust for the holders of Company
Share Certificates (the 'Common Shares Trust'). The Exchange Agent shall
determine the portion of the Common Shares Trust to which each holder of Company
Share Certificates shall be entitled, if any, by multiplying the amount of the
aggregate net proceeds comprising the Common Shares Trust by a fraction, the
numerator of which is the amount of the fractional share interest to which such
holder of
 
                                      A-5
 
<PAGE>

<PAGE>
Company Share Certificates would otherwise be entitled and the denominator of
which is the aggregate amount of fractional share interests to which all holders
of Company Share Certificates would otherwise be entitled.
 
     (c) As soon as practicable after the determination of the amount of cash,
if any, to be paid to holders of Company Share Certificates in lieu of any
fractional shares of Parent Class A Common Stock, the Exchange Agent shall pay
such amounts without interest to such holders of Company Share Certificates who
have surrendered their Company Share Certificates to the Exchange Agent.

                         REPRESENTATIONS AND WARRANTIES
 
     SECTION 3.01. Representations and Warranties of the Company. The Company
represents and warrants to Parent and Sub as follows:
 
          (a) Organization, Standing and Corporate Power. Each of the Company

     organized, validly existing and in good standing under the laws of the
     jurisdiction in which it is incorporated and has the requisite corporate
     power and authority to carry on its business as now being conducted. Each
     of the Company and each of its Subsidiaries is duly qualified or licensed
     to do business and is in good standing in each jurisdiction in which the
     nature of its business or the ownership or leasing of its properties makes
     such qualification or licensing necessary, other than in such jurisdictions
     where the failure to be so qualified or licensed (individually or in the
     aggregate) could not be reasonably expected to have a material adverse
     effect (as defined in Section 8.03) with respect to the Company. Attached
     as Section 3.01(a) of the disclosure schedule ('Disclosure Schedule')
     delivered to Parent by the Company at the time of execution of this
     Agreement are complete and correct copies of the Certificate of
     Incorporation and By-laws of the Company. The Company has delivered to
     Parent complete and correct copies of the articles of organization (or
     other organizational documents) and by-laws of each of its Subsidiaries, in
     each case as amended to the date of this Agreement, as well as correct and
     complete copies of all minutes of meetings of the Board of Directors and
     committees thereof of the Company since March 1995.
 
          (b) Subsidiaries. The only direct or indirect subsidiaries of the
     Company (other than subsidiaries of the Company that would not constitute
     in the aggregate a 'Significant Subsidiary' within the meaning of Rule 1-02
     of Regulation S-X of the Securities and Exchange Commission (the 'SEC'))
     are those listed in Section 3.01(b) of the Disclosure Schedule (the
     'Subsidiaries'). All the outstanding shares of capital stock of each such
     Subsidiary have been validly issued and are fully paid and nonassessable
     and are owned (of record and beneficially) by the Company, by another
     Subsidiary (wholly owned) of the Company or by the Company and another such
     Subsidiary (wholly owned), free and clear of all pledges, claims, liens,
     charges, encumbrances and security interests of any kind or nature
     whatsoever (collectively, 'Liens'). Except for the ownership interests set
     forth in Section 3.01(b) of the Disclosure Schedule, the Company does not
     own, directly or indirectly, any capital stock or other ownership interest,
     and does not have any option or similar right to acquire any assets or
     equity or other ownership interest, in any corporation, partnership,
     business association, joint venture or other entity.
 
          (c) Capital Structure. As of September 22, 1997, the authorized
     capital stock of the Company consists of (i) 75,000,000 shares of Company

     15,000,000 shares of preferred stock, each having a par value of one cent
     ($0.01) ('Preferred Stock'). As of the close of business on September 22,
     1997, there were (i) 32,139,334 shares of Company Common Stock, 0 shares of

     outstanding Company Stock Options. Schedule 3.01(c) sets forth the name of
     each holder of outstanding options to acquire shares of Company Common
     Stock, the number of options held and the exercise prices of such options.
     Except as set forth above, no shares of capital stock or other equity
     securities of the Company are issued, reserved for issuance or outstanding.
     All outstanding shares of capital stock of the Company are, and all shares
     which may be issued pursuant to the Stock Plans will be, when issued, duly
     authorized, validly issued, fully paid and nonassessable and not subject to
     preemptive rights. Other than the Convertible Debentures and the Company
     Stock Options, there are no outstanding bonds, debentures, notes or other
     indebtedness or other securities of the Company having the right to vote
     (or convertible into, or exchangeable or exercisable for, securities having
     the right to vote) on any matters on which stockholders of the Company may
     vote. Except as set forth above, there are no outstanding securities,
     options, warrants, calls, rights, commitments, agreements, arrangements or
     undertakings of any kind to which the Company or any of its subsidiaries is
     a party or by which any of them is bound obligating the Company or any of
     its subsidiaries to issue, deliver or sell, or cause to be issued,
     delivered or sold, additional shares of capital stock or other equity or
     voting securities of the Company or of any of its subsidiaries or
     obligating the Company or any of its subsidiaries to issue, grant, extend
     or enter into any such security, option, warrant, call, right, commitment,
     agreement, arrangement or undertaking. As of September 22, 1997, the only

     corporate and other power and authority to enter into this Agreement and,
     subject to the Company Stockholder Approval with respect to the

     obligation of the Company, enforceable against the Company in accordance

     Schedule, the execution and delivery of this Agreement do not, and the
     consummation of the transactions contemplated by this Agreement and
     compliance with the provisions hereof will not, conflict with, or result in
     any breach or violation of, or default (with or without notice or lapse of
     time, or both) under, or give rise to a right of termination, cancellation
     or acceleration of or 'put' right with respect to any obligation or to loss

     losses or Liens that individually or in the aggregate could not be
     reasonably expected to have a material adverse effect with respect to the
     Company or could not reasonably be expected to prevent or materially delay
     the ability of the Company to consummate the transactions contemplated by
     this Agreement. No consent, approval, order or authorization of, or
     registration, declaration or filing with, or notice to, any Federal, state
     or local government or any court, administrative agency or commission or
     other governmental authority or agency, domestic or foreign (a
     'Governmental Entity'), is required by or with respect to the Company or
     any of its subsidiaries in connection with the execution and delivery of
     this Agreement by the Company or the consummation by the Company of the
     transactions contemplated hereby or thereby, except, with respect to this

     1976, as amended (the 'HSR Act'), (ii) the filing with the SEC of (y) a
     proxy statement relating to the Company Stockholder Approval (such proxy
     statement as amended or supplemented from time to time, together with the

     necessary (as defined in Section 3.02(j)), the 'Joint Proxy Statement'),

     (the 'Exchange Act'), as may be required in connection with this Agreement
     and the transactions contemplated by this Agreement, (iii) the filing of
     the Certificate of Merger with the Secretary of State of the State of

     authorities in the necessary jurisdictions in the event Parent makes an
     election referred to in Section 1.01, and the filing of appropriate
     documents with the relevant authorities of other states in which the
     Company is qualified to do business and (iv) such other consents,
     approvals, orders, authorizations, registrations, declarations, filings or
     notices as are set forth in Section 3.01(d) of the Disclosure Schedule.
 
          (e) SEC Documents; Undisclosed Liabilities. The Company has filed all
     material required reports, schedules, forms, statements and other documents
     with the SEC since May 9, 1996, and the Company has delivered or made
     available to Parent all reports, schedules, forms, statements and other
     documents filed by the Company with the SEC since such date (collectively,
     and in each case including all exhibits and schedules thereto and documents
     incorporated by reference therein, the 'SEC Documents'). As of their
     respective dates, the SEC Documents complied in all material respects with
     the requirements of the Securities Act, or the Exchange Act, as the case
     may be, and the rules and regulations of the SEC promulgated thereunder
     applicable to such SEC Documents, and none of the SEC Documents (including
     any and all financial statements included therein) as of such dates
     contained any untrue statement of a material fact or omitted to state a
     material fact required to be stated therein or necessary in order to make
     the statements therein, in light of the circumstances under which they were
     made, not misleading. Except to the extent set forth in Section 3.01(e) of
     the Disclosure Schedule and except to the extent revised or superseded by a
     subsequent filing with the SEC (a copy of which has been provided to Parent
     prior to the date of this Agreement), none of the SEC Documents filed by
     the Company since January 1, 1997 and prior to the date of this Agreement
     (the 'Recent SEC Documents') contains any untrue statement of a material
     fact or omits to state any material fact required to be stated therein or
     necessary in order to make the statements therein, in light of the
     circumstances under which they were made, not misleading. The consolidated
     financial statements of the Company included in all SEC Documents filed
     since January 1, 1997 (the 'SEC Financial Statements') comply as to form in
     all material respects with applicable accounting requirements and the
     published rules and regulations of the SEC with respect thereto, have been
     prepared in accordance with generally accepted accounting principles
     (except, in the case of unaudited consolidated quarterly statements, as
     permitted by Form 10-Q of the SEC) applied on a consistent basis during the
     periods involved (except as may be indicated in the notes thereto) and
     fairly present the consolidated financial position of the Company and its
     consolidated subsidiaries as of the dates thereof and the consolidated
     results of their operations and cash flows for the periods then ended
     (subject, in the
 
                                      A-8
 
<PAGE>

<PAGE>
     case of unaudited quarterly statements, to normal year-end audit
     adjustments). Except as set forth in Schedule 3.01(e), at the date of the
     most recent audited financial statements of the Company included in the
     Recent SEC Documents, neither the Company nor any of its subsidiaries had,
     and since such date neither the Company nor any of such subsidiaries has
     incurred, any liabilities or obligations of any nature (whether accrued,
     absolute, contingent or otherwise) which, individually or in the aggregate,
     could reasonably be expected to have a material adverse effect with respect
     to the Company. To the best of the Company's knowledge, (i) all historical
     financial statements supplied to Parent by the Company for periods
     subsequent to June 30, 1997 have been prepared in accordance with generally
     accepted accounting principles (except as permitted by Form 10-Q of the
     SEC) applied on a consistent basis during the periods involved (except as
     may be indicated in the notes thereto) and fairly present the consolidated
     financial position of the Company and its consolidated subsidiaries as of
     the dates thereof and the consolidated results of their operations and cash
     flows for the periods then ended (subject to normal year-end adjustments)
     and (ii) all financial data so supplied for such periods is true and
     accurate in all material respects.
 
          (f) Information Supplied. None of the information supplied or to be
     supplied by the Company for inclusion or incorporation by reference in (i)
     the registration statement on Form S-4 to be filed with the SEC by Parent
     in connection with the issuance of Parent Class A Common Stock in the
     Merger (the 'Form S-4') will, at the time the Form S-4 is filed with the
     SEC, and at any time it is amended or supplemented or at the time it
     becomes effective under the Securities Act, contain any untrue statement of
     a material fact or omit to state any material fact required to be stated
     therein or necessary to make the statements therein not misleading, and
     (ii) the Joint Proxy Statement will, at the date it is first mailed to the
     Company's stockholders or at the time of the Company Stockholder Meeting
     (as defined in Section 5.01(b)), contain any untrue statement of a material
     fact or omit to state any material fact required to be stated therein or
     necessary in order to make the statements therein, in light of the
     circumstances under which they are made, not misleading. The Joint Proxy
     Statement will comply as to form in all material respects with the
     requirements of the Exchange Act and the rules and regulations promulgated
     thereunder, except that no representation is made by the Company with
     respect to statements made or incorporated by reference therein based on
     information supplied by Parent or Sub for inclusion or incorporation by
     reference in the Joint Proxy Statement.
 
          (g) Absence of Certain Changes or Events. Except as disclosed in
     Section 3.01(g) of the Disclosure Schedule or in the case of clause (ii),
     except as included in the Recent SEC Documents, since the date of the most
     recent audited financial statements included in the Recent SEC Documents
     (or, in the case of clauses (i) and (iii), since June 30, 1997), the
     Company has conducted its business in all material respects only in the
     ordinary course consistent with past practice, and there is not and has not
     been: (i) any material adverse change with respect to the Company (except
     for changes generally applicable to the economy in general and the specific
     industry in which the Company operates); (ii) any condition, event or
     occurrence which, individually or in the aggregate, could reasonably be
     expected to have a material adverse effect or give rise to a material
     adverse change with respect to the Company (except for changes generally
     applicable to the economy in general and the specific industry in which the
     Company operates); (iii) any event which, if it had taken place following
     the execution of this Agreement, would not have been permitted by Section
     4.01 without the prior consent of Parent; or (iv) any condition, event or
     occurrence which could reasonably be expected to prevent or materially
     delay the ability of the Company to consummate the transactions
     contemplated by this Agreement.
 
          (h) Litigation; Labor Matters; Compliance with Laws. (i) Schedule
     3.01(h) of the Disclosure Schedule set forth, as of the date of this
     Agreement, all suits, actions, counterclaims, proceedings or governmental
     or internal investigations pending or, to the knowledge of the Company,
     threatened in writing against or affecting the Company or any of its
     subsidiaries other than those which could not reasonably be expected to
     result in liability to the Company in excess of $150,000 in the aggregate.
     None of such suits, actions, counterclaims, proceedings or investigations
     (and no other suits, actions, counterclaims, proceedings or
     investigations), individually or in the aggregate, could reasonably be
     expected to have a material adverse effect with respect to the Company or
     prevent or materially delay the ability of the Company to consummate the
     transactions contemplated by
 
                                      A-9

     this Agreement or exploit all of the Company's licensed and other
     intellectual property rights; in addition, there is not any judgment,
     decree, injunction, rule or order of any Governmental Entity or arbitrator
     outstanding against the Company or any of its subsidiaries having, or
     which, insofar as reasonably could be foreseen by the Company, in the
     future could have, any such effect.
 
             (ii) Except as disclosed in Section 3.01(h)(ii) of the Disclosure
        Schedule, neither the Company nor any of its subsidiaries is a party to,
        or bound by, any collective bargaining agreement, contract or other
        agreement or understanding with a labor union or labor organization, nor
        is it or any of its subsidiaries the subject of any proceeding asserting
        that it or any subsidiary has committed an unfair labor practice or
        seeking to compel it to bargain with any labor organization as to wages
        or conditions of employment nor is there any strike, work stoppage or
        other labor dispute involving it or any of its subsidiaries pending or,
        to its knowledge, threatened, any of which could reasonably be expected
        to have a material adverse effect with respect to the Company.
 
             (iii) The conduct of the business of each of the Company and each
        of its subsidiaries and, to the knowledge of the Company, its
        contractors complies with all statutes, laws, regulations, ordinances,
        rules, judgments, orders, decrees or arbitration awards applicable
        thereto, including the Foreign Corrupt Practices Act, except for
        violations or failures so to comply, if any, that, individually or in
        the aggregate, could not reasonably be expected to have a material
        adverse effect with respect to the Company.
 
          (i) Absence of Changes in Employee Benefit Plans. Except as set forth
     on Schedule 3.01(i), since January 1, 1997, there has not been any adoption
     or amendment by the Company or any of its subsidiaries of any collective
     bargaining agreement or any bonus, pension, profit sharing, deferred
     compensation, incentive compensation, stock ownership, stock purchase,
     stock option, phantom stock, retirement, vacation, severance, disability,
     death benefit, hospitalization, medical or other plan, arrangement or
     understanding (whether formal or informal, oral or written) under which the
     Company or any of its subsidiaries currently has an obligation to provide
     benefits to any current or former employee, officer or director of the
     Company or any of its subsidiaries (collectively, 'Employee Benefit
     Plans'). Except as disclosed in Section 3.01(i) of the Disclosure Schedule,
     there exist no written employment, consulting, severance, change in
     control, termination or indemnification agreements or any oral agreement
     regarding compensation, benefits and other perquisites with respect to any
     employee expected to earn in excess of $100,000 in total compensation in
     1997, between the Company or any of its subsidiaries and any current or
     former employee, officer or director of the Company or any of its
     subsidiaries ('Employment Arrangements').
 
          (j) ERISA Plans. (i) Section 3.01(j) of the Disclosure Schedule
     contains a list of all 'employee pension benefit plans' (as defined in
     Section 3(2) of the Employee Retirement Income Security Act of 1974, as
     amended ('ERISA')) (sometimes referred to herein as 'Pension Plans'),
     'employee welfare benefit plans' (as defined in Section 3(1) of ERISA,
     hereinafter a 'Welfare Plan'), stock option, stock purchase, deferred
     compensation plans or arrangements, and other material employee fringe
     benefit plans or arrangements with respect to which the Company and its
     subsidiaries or any other person or entity that, together with the Company,
     is treated as a single employer under Section 414(b), (c), (m) or (o) of
     the Code (each, including the Company, a 'Commonly Controlled Entity') have
     any liability on account of any present or former officers, employees,
     directors or independent contractors of the Company (all the foregoing, in
     addition to Employee Benefit Plans defined in Section 3.01(i), collectively
     being herein called 'Benefit Plans'). The Company has made available to
     Parent true, complete and correct copies of (1) each Benefit Plan (or, in
     the case of any unwritten Benefit Plans, descriptions thereof), (2) the two
     most recent annual reports on Form 5500 and attached schedules filed with
     the Internal Revenue Service with respect to each Benefit Plan (if any such
     report was required by applicable law), (3) the most recent summary plan
     description for each Benefit Plan for which such a summary plan description
     is required by applicable law, (4) each trust agreement and material
     insurance or annuity contract relating to any Benefit Plan, (5) the most
     recent determination letter, if applicable, for any Benefit Plan and (6)
     each written Employment Arrangement.

             (ii) Except as disclosed in Section 3.01(j) of the Disclosure
        Schedule, each Benefit Plan has been established and administered in all
        material respects in accordance with its terms. All the Benefit Plans
        are in compliance in all material respects with the applicable
        provisions of ERISA, the Code and other applicable laws, rules and
        regulations. Except as disclosed in Section 3.01(j) of the Disclosure
        Schedule, all reports, returns and similar documents with respect to the
        Benefit Plans required to be filed with any governmental agency or
        distributed to any Benefit Plan participant have been duly and timely
        filed or distributed. Except as disclosed in Section 3.01(j) of the
        Disclosure Schedule, the Company has not received notice of any
        investigations by any governmental agency, termination proceedings or
        other claims (except claims for benefits payable in the normal operation
        of the Benefit Plans), suits or proceedings against or involving any
        Benefit Plan or asserting any rights or claims to benefits under any
        Benefit Plan that could give rise to any material liability, and, to the
        best of the Company's knowledge, there are not any facts that could give
        rise to any material liability in the event of any such investigation,
        claim, suit or proceeding. No event has occurred and no condition exists
        that could reasonably be expected to subject any Commonly Controlled
        Entity to any material tax, fine or penalty imposed by ERISA, the Code
        or other applicable laws, rules and regulations.
 
             (iii) Except as disclosed in Section 3.01(j) of the Disclosure
        Schedule, (1) all contributions to, and payments from, the Benefit Plans
        that may have been required to be made in accordance with the terms of
        the Benefit Plans, any applicable collective bargaining agreement and,
        when applicable, Section 302 of ERISA or Section 412 of the Code, have
        been timely made.
 
             (iv) Except as disclosed in Schedule 3.01(j), each Company Benefit
        Plan intended to qualify under Section 401(a) of the Code has been the
        subject of a determination letter from the Internal Revenue Service to
        the effect that such Benefit Plan is qualified and exempt from Federal
        income taxes under Sections 401(a) and 501(a), respectively, of the Code
        or application therefor has been timely made; no such determination
        letter has been revoked, and, to the knowledge of the Company,
        revocation has not been threatened nor is it expected.
 
             (v) Schedule 3.01(j) discloses whether: (1) any 'prohibited
        transaction' (as defined in Section 4975 of the Code or Section 406 of
        ERISA) has occurred during the past three years that involves the assets
        of any Benefit Plan that could subject the Company, any of its employees
        or a Company indemnified fiduciary under any Benefit Plan to a material
        tax or penalty on prohibited transactions imposed by Section 4975 of
        ERISA or the sanctions imposed under Title I of ERISA; or (2) any of the
        Company Benefit Plans has been terminated.
 
             (vi) Other than the ILGWU National Retirement Fund, no Commonly
        Controlled Entity sponsors, maintains, contributes to or has any
        liability in respect of any 'employee benefit plan' which is subject to
        Title IV of ERISA, including any multiemployer plan, multiple employer
        plan or single-employer plan.
 
             (vii) No Commonly Controlled Entity has incurred any material
        liability that remains unsatisfied to a Pension Plan (other than for
        contributions not yet due) or to the Pension Benefit Guaranty
        Corporation (other than for the payment of premiums not yet due).
 
             (viii) Except as disclosed in Schedule 3.01(j), no Commonly
        Controlled Entity has incurred any 'withdrawal liability' (as defined in
        Section 4201 of ERISA), which liability has not been fully paid as of
        the date hereof, or has announced an intention to withdraw, but has not
        yet completely withdrawn, from a 'multiemployer plan'; and, to the best
        of the Company's knowledge, no action has been taken, and no
        circumstances exist, that alone or with the passage of time could result
        in either a partial or complete withdrawal from such a Multiemployer
        Plan by any Commonly Controlled Entity.
 
          (k) Certain Employee Payments. Except as disclosed in Section 3.01(k)
     of the Disclosure Schedule, or as may be necessary or appropriate to give
     effect to Section 2.02 no Benefit Plan or Employment Arrangement provides
     for the payment to any current or former director or employee
 
                                      A-11

     of the Company or any Commonly Controlled Entity of any money, other
     property or rights, or accelerate other rights or benefits to any such
     employee or director as a result of the transactions contemplated by this
     Agreement, whether or not (i) such payment, acceleration or provision would
     constitute a 'parachute payment' (within the meaning of Section 280G of the
     Code), or (ii) some other subsequent action or event would be required to
     cause such payment, acceleration or provision to be triggered. Except as
     disclosed in Section 3.01(k) of the Disclosure Schedule, no payment,
     acceleration or provision referred to in the preceding sentence would
     constitute or give rise to a 'parachute payment' within the meaning of
     Section 280G of the Code.
 
          (l) Tax Returns and Tax Payments. The Company and each of its
     subsidiaries, and any consolidated, combined, unitary or aggregate group
     for Tax purposes of which the Company or any of its subsidiaries is or has
     been a member (a 'Consolidated Group') has timely filed all Tax Returns
     required to be filed by it and has paid all Taxes shown thereon to be due.
     The Company and its subsidiaries have made adequate provision (to the
     extent required by, and in accordance with generally accepted accounting
     principles ('GAAP')) for all Taxes payable for any periods that end before
     the Effective Time of the Merger for which no Tax Returns have yet been
     filed and for any periods that begin before the Effective Time of the
     Merger and end after the Effective Time of the Merger to the extent such
     Taxes are attributable to the portion of any such period ending at the
     Effective Time of the Merger, and the charges, accruals and reserves for
     Taxes reflected in the financial statements of the Company and its
     subsidiaries are adequate under GAAP to cover the Tax liability accruing or
     payable by the Company and its subsidiaries in respect of periods prior to
     the date hereof. Except as set forth in Section 3.01(l) of the Disclosure
     Schedule: (i) no material claim for unpaid Taxes has become a lien against
     the property of the Company or any of its subsidiaries or is being asserted
     against the Company or any of its subsidiaries, (ii) no audit or other
     proceeding with respect to any Taxes due from the Company or any of its
     subsidiaries or any Tax Return of the Company or any of its subsidiaries is
     pending, threatened, to the best of the Company's knowledge, or being
     conducted by a Tax authority, and (iii) no extension of the statute of
     limitations on the assessment of any Taxes has been granted by the Company
     nor any of its subsidiaries and is currently in effect, (iv) neither the
     Company or any of its subsidiaries (A) has been a member of a Consolidated
     Group filing a consolidated federal income Tax Return (other than a group
     the common parent of which was the Company) or (B) has any liability for
     the Taxes of any person (other than the Company and its subsidiaries),
     including liability arising from the application of Treasury Regulation
     section 1.1502-6 or any analogous provision of state, local or foreign law,
     or as a transferee or successor, by contract, or otherwise, (v) no consent
     under Section 341(f) of the Code has been filed with respect to the Company
     or any of its subsidiaries and (vi) all Taxes required to be withheld,

          (p) Brokers. No broker, investment banker, financial advisor or other
     person other than Merrill Lynch, Pierce, Fenner & Smith Incorporated is
     entitled to any broker's, finder's, financial advisor's or other similar
     fee or commission in connection with the transactions contemplated by this
     Agreement based upon arrangements made by or on behalf of the Company.
 
          (q) Opinion of Financial Advisor. The Company has received the opinion
     of Merrill Lynch, Pierce, Fenner & Smith Incorporated, dated the date of
     this Agreement, to the effect that, as of the date thereof, the Exchange
     Ratio is fair, from a financial point of view, to the holders of the
     Company Common Stock (other than the Stockholder and its affiliates and
     Parent and its affiliates).
 
          (r) Board Recommendation. The Board of Directors of the Company, at a
     meeting duly called and held, has (i) determined that this Agreement and
     the transactions contemplated hereby, including the Merger, and the Stock
     Exchange Agreement and the transactions contemplated thereby, including the
     Exchange, taken together, are fair to and in the best interests of the
     stockholders of the Company (other than the Stockholder and its
     affiliates), and (ii) resolved to recommend that the holders of the shares
     of Company Common Stock approve and adopt this Agreement and the
     transactions contemplated herein, including the Merger.
 
          (s) Required Company Vote. The Company Stockholder Approval, being the
     affirmative vote of a majority of the outstanding shares of Company Common
     Stock, is the only vote of the holders of any class or series of the
     Company's securities necessary to approve and adopt the Merger Agreement,
     the Merger and the other transactions contemplated hereby. There is no vote
     of the holders of any class or series of the Company's securities necessary
     to approve the Stock Exchange Agreement or the transactions contemplated
     thereby.
 
          (t) Properties. Except as disclosed in Schedule 3.01(t) hereto, each
     of the Company and its subsidiaries (i) has good and marketable title to
     all the properties and assets reflected in the latest audited balance sheet
     included in the Recent SEC Documents as being owned by the Company or one
     of its subsidiaries or acquired after the date thereof which are,
     individually or in the aggregate, material to the Company's business on a
     consolidated basis (except properties sold or otherwise disposed of since
     the date thereof in the ordinary course of business), free and clear of (A)
     all Liens except (1) statutory liens securing payments not yet due and (2)
     such imperfections or irregularities of title, or other Liens (other than
     real property mortgages or deeds of trust) as do not materially affect the
     use of the properties or assets subject thereto or affected thereby or
     otherwise materially impair business operations at such properties, and (B)
     all real property mortgages and deeds of trust and (ii) is the lessee of
     all leasehold estates reflected in Schedule 3.01(t) hereto or acquired
     after the date thereof which are material to its business on a consolidated
     basis and is in possession of the properties purported to be leased
     thereunder, and each such lease is in full force and effect and is valid
     without material default (and the lessee has not received any notice of
     default, whether or not material) thereunder by the lessee or, to the
     Company's knowledge, the lessor.
 
          (u) Trademarks and Related Contracts. The Company and each of its
     subsidiaries owns the trademarks (including common law names and marks and
     federally registered names and marks) set forth on Schedule 3.01(u) in the
     United States and throughout the world, and owns and or is licensed to use
     (in each case, clear of any Liens), all patents, trademarks, trade names,
     copyrights, technology, know-how and processes used in or necessary for the
     conduct of its business as currently conducted which are material to the
     condition (financial and other), business, or operations of the Company
     (including all exclusive licensed rights in and to the names and trademarks
     'Calvin Klein,' 'CK/Calvin Klein,' 'Calvin Klein Jeans,' 'CK/Calvin Klein
     Jeans,' 'Calvin Klein Khakis' and 'CK/Calvin Klein Khakis' (and variations
     thereof) for, on and in connection with certain men's and women's jeans and
     jeans-related items, khakis and khaki-related items and boys' and girls'
     jeans and jeans-related items in the United States, its territories and
     possessions, Mexico, Canada, South America and Central America (as more
     fully described in Schedule 3.01(u) hereto) and any variations or
     derivatives thereof used by the Company or its subsidiaries and its
     licensees, agents and distributors). To the best knowledge of the Company,
     (i) the use of such patents, trademarks, trade names, service marks,
     copyrights, technology, know-how
 
                                      A-15

     and processes by the Company and its subsidiaries and authorized users does
     not infringe on the rights of any person, subject to such claims and
     infringements as do not, in the aggregate, give rise to any liability on
     the part of the Company and its subsidiaries which could have a material
     adverse effect with respect to the Company and (ii) no person is infringing
     on any right of the Company or any of its subsidiaries, licensees or
     authorized users with respect to any such patents, trademarks, service
     marks, trade names, copyrights, technology, know-how or processes, except
     in each of cases (i) or (ii) as set forth on Schedule 3.01(u). The Company
     and its subsidiaries, and, to the best of the Company's knowledge,
     licensees or authorized users are not in breach or violation in any
     material respect of any agreement relating to the use of any of the
     intellectual property identified in this provision, and they have not
     received any notification written or oral from any third party that there
     is any such violation, breach or inability to perform under any such
     agreement. There are no agreements, written or oral, except as set forth in
     Schedule 3.01(u), which in any material respect limit or otherwise relate
     to any rights by the Company or its shareholders to use any of its
     intellectual property.
 
          (v) Transactions with Affiliates. Except as set forth on Schedule
     3.01(v) and in the SEC Documents, from January 1, 1996 through the date of
     this Agreement, there has been no transaction, agreement, arrangement or
     understanding, or any related series thereof, between the Company or its
     subsidiaries or contractors, on the one hand, and the Company's affiliates
     (other than wholly-owned (excluding directors' and nominee shares)
     subsidiaries of the Company), on the other hand, in which the amount or
     value involved exceeded $60,000. As used in the definition of 'affiliate,'
     the term 'control' means possession, directly or indirectly, of the power
     to direct or cause the direction of the management or policies of a person,
     whether through the ownership of voting securities, by contract or
     otherwise.
 
     SECTION 3.02. Representations and Warranties of Parent and Sub. Parent and
Sub represent and warrant to the Company as follows:
 
          (a) Organization, Standing and Corporate Power. Each of Parent, Sub
     and the other Parent Subsidiaries (as defined in Section 3.02(b)) is duly
     organized, validly existing and in good standing under the laws of the
     jurisdiction in which it is incorporated and has the requisite corporate
     power and authority to carry on its business as now being conducted. Each
     of Parent, Sub and the other Parent Subsidiaries is duly qualified or
     licensed to do business and is in good standing in each jurisdiction in
     which the nature of its business or the ownership or leasing of its
     properties makes such qualification or licensing necessary, other than in
     such jurisdictions where the failure to be so qualified or licensed
     (individually or in the aggregate) could not reasonably be expected to have
     a material adverse effect with respect to Parent. Parent has delivered to
     the Company complete and correct copies of its Restated Certificate of
     Incorporation and By-laws and the certificate of incorporation (or other
     organizational documents) and by-laws of Sub and the Significant
     Subsidiaries of Parent as listed in Section 3.02(b) of the disclosure
     schedule (the 'Parent Disclosure Schedule') delivered to the Company by
     Parent at the time of execution of this Agreement, in each case as amended
     to the date of this Agreement.
 
          (b) Subsidiaries. The only direct or indirect subsidiaries of Parent
     (other than such subsidiaries that would not constitute in the aggregate a
     Significant Subsidiary) are listed in Section 3.02(b) of the Parent
     Disclosure Schedule (together with Sub, the 'Parent Subsidiaries'). All the
     outstanding shares of capital stock of each such Parent Subsidiary have
     been validly issued and are fully paid and nonassessable and are owned (of
     record and beneficially) by Parent, by another Parent Subsidiary (wholly
     owned) or by Parent and another such Parent Subsidiary (wholly owned), free
     and clear of all Liens. Except for the ownership interests set forth in
     Section 3.02(b) of the Parent Disclosure Schedule, Parent does not own,
     directly or indirectly, any capital stock or other ownership interest, and
     does not have any option or other right to acquire any assets or equity or
     other ownership interest in any corporation, partnership, business
     association, joint venture or other entity.
 
          (c) Capital Structure. The authorized capital stock of Parent consists
     of (i) 130,000,000 shares of Parent Class A Common Stock and (ii)
     10,000,000 shares of preferred stock, par value $0.01 per share ('Parent
     Preferred Stock'). As of the close of business on September 22, 1997, there
     are (i)
 
                                      A-16
 
<PAGE>

<PAGE>
     52,097,548 shares of Parent Class A Common Stock and no shares of Parent
     Preferred Stock issued and outstanding; (ii) 739,363 shares of Parent Class
     A Common Stock held in the treasury of Parent; and (iii) 8,441,164 shares
     of Parent Class A Common Stock reserved for issuance pursuant to the
     Employee Stock Plan, the 1993 Stock Plan for Non-Employee Directors, and
     the Amended and Restated 1993 Stock Plan (the 'Parent Stock Plans'). Except
     as set forth above, no shares of capital stock or other equity securities
     of Parent are issued, reserved for issuance or outstanding. All outstanding
     shares of capital stock of Parent are, and all shares which may be issued
     pursuant to this Agreement will be, when issued, duly authorized, validly
     issued, fully paid and nonassessable and not subject to preemptive rights.
     There are no outstanding bonds, debentures, notes or other indebtedness or
     other securities of Parent having the right to vote (or convertible into,
     or exchangeable for, securities having the right to vote) on any matters on
     which stockholders of Parent may vote. Except as set forth above, there are
     no outstanding securities, options, warrants, calls, rights, commitments,
     agreements, arrangements or undertakings of any kind to which Parent or any
     of its subsidiaries is a party or by which any of them is bound obligating
     Parent or any of its subsidiaries to issue, deliver or sell, or cause to be
     issued, delivered or sold, additional shares of capital stock or other
     equity or voting securities of Parent or any of its subsidiaries or
     obligating Parent or any of its subsidiaries to issue, grant, extend or
     enter into any such security, option, warrant, call, right, commitment,
     agreement, arrangement or undertaking. Other than pursuant to the Parent
     Stock Plans and the Citibank Equity Options Stock Buyback Program, there
     are no outstanding contractual obligations, commitments, understandings or
     arrangements of Parent or any of its subsidiaries to repurchase, redeem or
     otherwise acquire or make any payment in respect of any shares of capital
     stock of Parent or any of its subsidiaries. The authorized capital stock of
     Sub consists of 100 shares of common stock, par value $0.01 per share, all
     of which have been validly issued, are fully paid and nonassessable and are
     owned by Parent, free and clear of any Lien.
 
          (d) Authority; Noncontravention. Parent and Sub have all requisite
     corporate and other power and authority to enter into this Agreement and,
     subject to the Parent Stockholder Approval, to consummate the transactions
     contemplated hereby and thereby. The execution and delivery of this
     Agreement by Parent and Sub and the consummation by Parent and Sub of the
     transactions contemplated hereby and thereby have been duly authorized by
     all necessary corporate action on the part of Parent and Sub, subject to
     the Parent Stockholder Approval. This Agreement has been duly executed and
     delivered by each of Parent and Sub and constitutes a valid and binding
     obligation of each of Parent and Sub, enforceable against such party in
     accordance with its terms. The execution and delivery of this Agreement do
     not, and the consummation of the transactions contemplated by this
     Agreement and compliance with the provisions of this Agreement will not,
     conflict with, or result in any breach or violation of, or default (with or
     without notice or lapse of time, or both) under, or give rise to a right of
     termination, cancellation or acceleration of or 'put' right with respect to
     any obligation or to loss of a material benefit under, or result in the
     creation of any Lien upon any of the properties or assets of Parent or any
     of its subsidiaries under, (i) the certificate of incorporation or by-laws
     of Parent or Sub or the comparable charter or organizational documents of
     any other subsidiary of Parent, (ii) any loan or credit agreement, note,
     bond, mortgage, indenture, lease or other agreement, instrument, permit,
     concession, franchise or license applicable to Parent, Sub or any other
     subsidiary of Parent or their respective properties or assets or (iii)
     subject to the governmental filings and other matters referred to in the
     following sentence, any judgment, order, decree, statute, law, ordinance,
     rule, regulation or arbitration award applicable to Parent, Sub or any
     other subsidiary of Parent or their respective properties or assets, other
     than, in the case of clauses (ii) and (iii), any such conflicts, breaches,
     violations, defaults, rights, losses or Liens that individually or in the
     aggregate could not reasonably be expected to have a material adverse
     effect with respect to Parent or could not reasonably be expected to
     prevent or materially delay the ability of Parent to consummate the
     transactions contemplated by this Agreement. No consent, approval, order or
     authorization of, or registration, declaration or filing with, or notice
     to, any Governmental Entity is required by or with respect to Parent, Sub
     or any other subsidiary of Parent in connection with the execution and

     hereby or thereby, except, with respect to this Agreement, for (i) the
     filing of a premerger notification and report form under the HSR Act, (ii)
     the filing with the SEC of (y) the Joint Proxy Statement relating to the
     Parent Stockholder Approval and the Form S-4 and (z) such reports under the
     Exchange Act as may be required in connection with this Agreement and the
     transactions contemplated by this Agreement, (iii) the filing of the
     Certificate of Merger with the Secretary of State of the State of Delaware,
     the filing of a certificate of merger with the appropriate authorities in
     the necessary jurisdictions in the event Parent makes an election referred
     to in Section 1.01 and the filing of appropriate documents with the
     relevant authorities of other states in which the Company is qualified to
     do business and (iv) such other consents, approvals, orders,
     authorizations, registrations, declarations, filings or notices as may be
     required under the 'takeover' or 'blue sky' laws of various states.
 
          (e) SEC Documents; Undisclosed Liabilities. Parent has filed all
     material required reports, schedules, forms, statements and other documents
     with the SEC since January 1, 1996, and Parent has delivered or made
     available to the Company all reports, schedules, forms, statements and
     other documents filed with the SEC since such date (collectively, and in
     each case including all exhibits and schedules thereto and documents
     incorporated by reference therein, the 'Parent SEC Documents'). As of their
     respective dates, the Parent SEC Documents complied in all material
     respects with the requirements of the Securities Act or the Exchange Act,
     as the case may be, and the rules and regulations of the SEC promulgated
     thereunder applicable to such Parent SEC Documents, and none of the Parent
     SEC Documents (including any and all consolidated financial statements
     included therein) as of such date contained any untrue statement of a
     material fact or omitted to state a material fact required to be stated
     therein or necessary in order to make the statements therein, in light of
     the circumstances under which they were made, not misleading. Except to the
     extent set forth in Section 3.02(e) of the Parent Disclosure Schedule and
     except to the extent revised or superseded by a subsequent filing with the
     SEC (a copy of which has been provided to the Company prior to the date of
     this Agreement), none of the Parent SEC Documents filed by Parent since
     January 1, 1997 and prior to the date of this Agreement (the 'Recent Parent
     SEC Documents') contains any untrue statement of a material fact or omits
     to state any material fact required to be stated therein or necessary in
     order to make the statements therein, in light of the circumstances under
     which they were made, not misleading. The consolidated financial statements
     of Parent included in such Recent Parent SEC Documents comply as to form in
     all material respects with applicable accounting requirements and the
     published rules and regulations of the SEC with respect thereto, have been
     prepared in accordance with generally accepted accounting principles
     (except, in the case of unaudited consolidated quarterly statements, as
     permitted by Form 10-Q of the SEC) applied on a consistent basis during the
     periods involved (except as may be indicated in the notes thereto) and
     fairly present the consolidated financial position of Parent and its
     consolidated subsidiaries as of the dates thereof and the consolidated
     results of their operations and cash flows for the periods then ended
     (subject, in the case of unaudited quarterly statements, to normal year-end
     audit adjustments). Except as set forth in Schedule 3.02(e), at the date of
     the most recent audited financial statements of Parent included in the
     Recent Parent SEC Documents, neither Parent nor any of its subsidiaries
     had, and since such date neither Parent nor any of such subsidiaries has
     incurred, any liabilities or obligations of any nature (whether accrued,
     absolute, contingent or otherwise) which, individually or in the aggregate,
     could reasonably be expected to have a material adverse effect with respect
     to Parent.
 
          (f) Information Supplied. None of the information supplied or to be
     supplied by Parent or Sub for inclusion or incorporation by reference in
     (i) the Form S-4 will, at the time the Form S-4 is filed with the SEC, and
     at any time it is amended or supplemented or at the time it becomes
     effective under the Securities Act, contain any untrue statement of a
     material fact or omit to state any material fact required to be stated
     therein or necessary to make the statements therein not misleading, and
     (ii) the Joint Proxy Statement will, at the date it is first mailed to
     Parent's stockholders or at the time of the Parent Stockholder Meeting (as
     defined in Section 5.01(c)), if such meeting is being held, contain any
     untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary in order to make the statements
     therein, in light of the circumstances under which they are made, not
     misleading. The Form S-4 will comply as
 
                                      A-18
 
<PAGE>

<PAGE>
     to form in all material respects with the requirements of the Securities
     Act and the rules and regulations promulgated thereunder, except that no
     representation or warranty is made by Parent or Sub with respect to
     statements made or incorporated by reference therein based on information
     supplied by the Company for inclusion or incorporation by reference in the
     Form S-4.
 
          (g) Absence of Certain Changes or Events. Except as disclosed in
     Section 3.02(g) of the Disclosure Schedule or, in the case of clause (ii),
     except as included in the Recent Parent SEC Documents, since the date of
     the most recent audited financial statements included in such Recent Parent
     SEC Documents (or, in the case of clauses (i) and (iii), since June 30,
     1997), Parent has conducted its business in all material respects only in
     the ordinary course consistent with past practice, and there is not and has
     not been (i) any material adverse change with respect to Parent (except for
     changes generally applicable to the economy in general and the specific
     industry in which Parent operates); (ii) any condition, event or occurrence
     which, individually or in the aggregate, could reasonably be expected to
     have a material adverse effect or give rise to a material adverse change
     with respect to Parent; (iii) any event which, if it had taken place
     following the execution of this Agreement, would not have been permitted by
     Section 4.02 without the prior consent of the Company; or (iv) any
     condition, event or occurrence which could reasonably be expected to
     prevent or materially delay the ability of Parent to consummate the
     transactions contemplated by this Agreement.
 
          (h) Brokers. No broker, investment banker, financial advisor or other
     person other than Lazard Freres & Co. LLC is entitled to any broker's,
     finder's, financial advisor's or other similar fee or commission in
     connection with the transactions contemplated by this Agreement based upon
     arrangements made by or on behalf of Parent.
 
          (i) Opinion of Financial Advisor. Parent has received the opinion of
     Lazard Freres & Co. LLC, dated the date of this Agreement, to the effect
     that the Exchange Ratio in connection with the Exchange and the Merger,
     taken as a whole, is fair, from a financial point of view, to Parent and
     the holders of the Parent Class A Common Stock.
 
          (j) Required Parent Stockholder Vote. The issuance of shares in
     connection with the transactions contemplated hereby would, to the extent
     required by the applicable regulations of the NYSE, require the affirmative
     vote of the holders of a majority of the shares of Parent Class A Common
     Stock present in person or represented by proxy and entitled to vote at the
     Parent Stockholder Meeting. The stockholder action specified above is
     collectively referred to as the 'Parent Stockholder Approval.'
 
          (k) Interim Operations of Sub. Sub was formed on September 18, 1997
     solely for the purpose of engaging in the transactions contemplated hereby
     and, in all material respects, has engaged in no other business activities
     and has conducted its operations only as contemplated hereby, except that
     Sub is required in accordance with the terms of the existing bank credit
     agreement of Warnaco Inc., a wholly owned subsidiary of Parent, to
     guarantee Warnaco Inc.'s obligations thereunder.
 
          (l) Board Recommendation. The Board of Directors of Parent, at a
     meeting duly called and held, has (i) determined that this Agreement and
     the transactions contemplated hereby, including the issuance of shares of
     Parent Class A Common Stock in the Merger and the Exchange, are fair to and
     in the best interests of the stockholders of Parent, and (ii) resolved to
     recommend that the holders of the shares of Parent Class A Common Stock
     approve the issuance of shares of Parent Class A Common Stock in connection
     with the Merger and the transactions contemplated hereby.
 
          (m) Certain Employee Payments. No Benefit Plan or Employment
     Arrangement provides for the payment to any current or former director or
     employee of Parent of any money or other property or rights or accelerates
     or provides any other rights or benefits to any such employee or director
     as a result of the transactions contemplated by this Agreement, whether or
     not (i) such payment, acceleration or provision would constitute a
     'parachute payment' (within the meaning of Section 280G of the Code), or
     (ii) some other subsequent action or event would be required to cause such
     payment, acceleration or provision to be triggered.
 
          (n) Tax Returns and Tax Payments. Parent and each of its subsidiaries,
     and any consolidated, combined, unitary or aggregate group for Tax purposes
     of which Parent or any of its subsidiaries is
 
                                      A-19
 
<PAGE>

<PAGE>
     or has been a member has timely filed all Tax Returns required to be filed
     by it and has paid all Taxes shown thereon to be due, except to the extent
     that any such failure to file or pay could not reasonably be expected to
     have a material adverse effect on Parent.
 
          (o) Litigation, Compliance With Law. (i) There are no suits, actions,
     counterclaims, proceedings or investigations pending or, to the knowledge
     of Parent, threatened in writing against Parent or any of its subsidiaries
     other than those which, individually or in the aggregate, could not
     reasonably be expected to have a material adverse effect with respect to
     Parent.
 
             (ii) The conduct of the business of each of Parent and each of its
        subsidiaries and, to the knowledge of Parent, its contractors complies
        with all statutes, laws, regulations, ordinances, rules, judgments,
        orders, decrees or arbitration awards applicable thereto, including the
        Foreign Corrupt Practices Act, except for violations or failures so to
        comply, if any, that, individually or in the aggregate, could not
        reasonably be expected to have a material adverse effect with respect to
        Parent.
 
          (p) Material Contract Defaults. Neither Parent nor any of its
     subsidiaries is, or has received any notice or has any knowledge that any
     other party is, in default or unable to perform in any respect under any of
     its Material Contracts, including any license or agreement relating to
     intellectual property, except for those defaults or inabilities to perform
     which could not reasonably be expected, either individually or in the
     aggregate, to have a material adverse effect with respect to Parent.
 
          (q) Assets. The assets, properties, rights and contracts, including
     (as applicable), title or leaseholds thereto, of Parent and its
     subsidiaries, taken as a whole, are sufficient to permit Parent and its
     subsidiaries to conduct their business as currently being conducted with
     only such exceptions as could not be reasonably expected to have a material
     adverse effect on Parent.
 
          (r) Trademarks and Related Contracts. Parent and each of its
     subsidiaries owns and/or is licensed to use (in each case, clear of any
     Liens), all patents, trademarks, trade names, copyrights, technology,
     know-how and processes used in or necessary for the conduct of its business
     as currently conducted which are material to the condition (financial and
     other), business, or operations of the Company, except to the extent any
     such failure could not reasonably be expected to have a material adverse
     effect on Parent.

<PAGE>

<PAGE>
of this Agreement), Parent shall, to the extent consistent with Parent's
reasonable commercial judgment and to the extent material, use its reasonable
best efforts to preserve intact its and its subsidiaries' current business
organizations, keep available the services of their current officers and
employees and preserve their relationships with customers, suppliers, licensors,
licensees, advertisers, distributors and others having business dealings with
them to the end that their goodwill and ongoing businesses shall be materially
unimpaired at the Effective Time of the Merger.
 
     (b) Without limiting the generality of the foregoing, during the period

shall not, without the prior written consent of the Company (which consent will
not be unreasonably withheld and shall be deemed granted if not denied within 48
hours after written notice to the Company), adopt a plan of complete or partial
liquidation or resolutions providing for or authorizing such a liquidation or a
dissolution, merger, consolidation, restructuring, recapitalization or
reorganization.
 
                                   ARTICLE V

                             ADDITIONAL AGREEMENTS
 
     SECTION 5.01. Preparation of Form S-4 and the Joint Proxy Statement;
Stockholder Meetings. (a) Promptly following the execution of this Agreement,
the Company and Parent shall prepare and file with the SEC the Joint Proxy
Statement, and Parent shall prepare and file with the SEC the Form S-4, in which
the Joint Proxy Statement will be included as a prospectus. Each of the Company
and Parent shall use its reasonable best efforts to have the Form S-4 declared
effective under the Securities Act as promptly as practicable after such filing.
The Company will use its reasonable best efforts to cause the Joint Proxy
Statement to be mailed to the Company's stockholders, and Parent will use its
reasonable best efforts to cause the Joint Proxy Statement to be mailed to
Parent's stockholders, in each case as promptly as practicable after the Form
S-4 is declared effective under the Securities Act. The information provided and
to be provided by Parent, Sub and the Company, respectively, for use in the Form
S-4 shall, at the time the Form S-4 becomes effective and on the dates of each
of the Company Stockholder Meeting and the Parent Stockholder Meeting, be true
and correct in all material respects and shall not omit to state any material
fact required to be stated therein or necessary in order to make such
information not misleading, and the Company, Parent and Sub each agree to
correct immediately upon the discovery thereof any information provided by it
for use in the Form S-4 which shall have become false or misleading.
 
     (b) Unless the Board of Directors of the Company shall take any action
permitted by the fifth sentence of this Section 5.01(b), the Company shall cause
a meeting of its stockholders (the 'Company Stockholder Meeting') to be duly
called and held as soon as practicable after the date of this Agreement for the
purpose of voting on the approval and adoption of this Agreement and the Merger.
The Board of Directors of the Company shall set the record date for the Company
Stockholder Meeting to occur immediately following the consummation of the
Exchange so that (and only if) Parent is the holder of record for purposes of
such Company Stockholder Meeting of the shares of Company Common Stock acquired
in the Exchange, which shares shall constitute in excess of a majority of the
issued and outstanding shares of Company Common Stock. In the event that it
becomes necessary to delay the date of the Company Stockholder Meeting, the
Company shall use its best efforts to ensure that any such delay does not
frustrate the purpose of the immediately preceding sentence, including by
issuing shares of Company Common Stock in accordance with Section 5.19
immediately prior to setting any new record date. The Board of Directors of the
Company shall recommend approval and adoption of this Agreement and the Merger
by the Company's stockholders. The Board of Directors of the Company shall not
be permitted to withdraw, amend or modify in a manner adverse to Parent such
recommendation (or announce publicly its intention to do so), except that prior
to the consummation of the Exchange, the Board of Directors shall be permitted
to withdraw, amend or modify its recommendation (or publicly announce its
intention to do so) but only if (i) the Company has complied with Section 5.13,
(ii) an Alternative Transaction (as defined in Section 7.01) shall have been
proposed by any person other than Parent or its affiliates, (iii) the Company
shall have notified Parent of such Alternative Transaction at least five
business days in advance of such withdrawal, amendment or modification and (iv)
the Board of Directors of the Company shall have determined in its good faith
 
                                      A-23
 
<PAGE>

<PAGE>
judgment that such Alternative Transaction is more favorable to the Company's
stockholders than this Agreement and the Merger and, as a result, the Board of
Directors of the Company shall have determined in good faith, based upon the
advice of outside counsel, that it is obligated by its fiduciary obligations
under applicable law to modify, amend or withdraw such recommendation; provided
that no such withdrawal, amendment or modification shall be made unless the
Company shall have delivered to Parent in accordance with Section 5.13(b) a
written notice advising Parent that the Board of Directors of the Company has
received an Acquisition Proposal and identifying the person making such
Acquisition Proposal.
 
     (c) Unless the Board of Directors of the Company shall take any action
permitted by the fifth sentence of paragraph (b) above, and only to the extent
required by applicable regulations of the NYSE, Parent shall cause a meeting of
its stockholders (the 'Parent Stockholder Meeting') to be called and held as
soon as reasonably practicable after the date of this Agreement for the purpose
of voting on the issuance of shares of Parent Class A Common Stock in connection
with the transactions contemplated hereby and, at such meeting, the Board of
Directors of Parent shall recommend approval by Parent's stockholders of such
issuance of shares of Parent Class A Common Stock. Nothing contained in this
Section 5.01(c) shall prohibit Parent from making any disclosure to Parent's
stockholders if, in the good faith judgment of the Board of Directors of Parent,
upon the advice of counsel, failure to make such disclosure would be
inconsistent with applicable laws.
 
     (d) If the Parent Stockholder Meeting is being held, the recommendations of
the Boards of Directors of Parent and the Company referred to in paragraphs (b)
and (c) above, together with copies of the opinions referred to in Sections
3.01(q) and 3.02(i), shall be included in the Joint Proxy Statement. Parent and
the Company will use reasonable efforts to hold such meetings on the same day
and use their best efforts to hold such meetings as soon as practicable after
the date hereof.
 
     (e) The Company will cause its transfer agent to make stock transfer
records relating to the Company available to the extent reasonably necessary to
effectuate the intent of this Agreement.
 
     SECTION 5.02. Letter of the Company's Accountants. The Company shall use
its reasonable best efforts to cause to be delivered to Parent a letter of
Coopers & Lybrand LLP, the Company's independent public accountants, dated a
date within two business days before the date on which the Form S-4 shall become
effective and addressed to Parent, in form and substance reasonably satisfactory
to Parent and customary in scope and substance for letters delivered by
independent public accountants in connection with registration statements
similar to the Form S-4. In connection with the Company's efforts to obtain such
letter, if requested by Coopers & Lybrand LLP, Parent shall provide a
representation letter to Coopers & Lybrand LLP complying with SAS 72, if then
required.
 
     SECTION 5.03. Letter of Parent's Accountants. Parent shall use its
reasonable best efforts to cause to be delivered to the Company a letter of
Price Waterhouse LLP, Parent's independent public accountants, dated a date
within two business days before the date on which the Form S-4 shall become
effective and addressed to the Company, in form and substance reasonably
satisfactory to the Company and customary in scope and substance for letters
delivered by independent public accountants in connection with registration
statements similar to the Form S-4. In connection with the Parent's efforts to
obtain such letter, if requested by Price Waterhouse LLP, the Company shall
provide a representation letter to Price Waterhouse LLP complying with SAS 72,
if then required.
 
     SECTION 5.04. Access to Information; Confidentiality. (a) The Company
shall, and shall cause its subsidiaries, officers, employees, counsel, financial
advisors and other representatives to, afford to Parent and its representatives
reasonable access during normal business hours during the period prior to the
Effective Time of the Merger to its properties, books, contracts, commitments,
personnel and records and, during such period, the Company shall, and shall
cause its subsidiaries, officers, employees and representatives to, furnish
promptly to Parent (i) a copy of each report, schedule, registration statement
and other document filed by it during such period pursuant to the requirements
of Federal or state securities laws and (ii) all other information concerning
its business, properties, financial condition, operations and personnel as such
other party may from time to time reasonably request. During the period prior to
the Effective Time of the Merger, Parent shall provide the Company and its
representatives with reasonable access during normal business hours to its
properties, books, contracts, commitments, personnel and records as may be
necessary to enable the Company to confirm the
 
                                      A-24
 
<PAGE>

<PAGE>
accuracy of the representations and warranties of Parent set forth herein and
compliance by Parent and Sub of their obligations hereunder, and, during such
period, Parent shall, and shall cause its subsidiaries, officers, employees and
representatives to, furnish promptly to the Company (i) a copy of each report,
schedule, registration statement and other document filed by it during such
period pursuant to the requirements of Federal or state securities laws and (ii)
all other information concerning its business, properties, financial condition,
operations and personnel as such other party may from time to time reasonably
request. The foregoing shall not require Parent or the Company to share any
information with respect to legal proceedings that could reasonably be expected
to give rise to a breach of attorney-client privilege. Parent will hold, and
will cause its directors, officers, employees, accountants, counsel, financial
advisors and other representatives to hold, any nonpublic information of the
Company in confidence to the extent required by, and in accordance with, the
provisions of the letter dated September 11, 1997, between Parent and the
Company (the 'Confidentiality Agreement'). The Company will hold, and will cause
its directors, officers, employees, accountants, counsel, financial advisors and
other representatives to hold, any nonpublic information of Parent in confidence
to the same extent Parent is required to hold nonpublic information of the
Company in confidence pursuant to the Confidentiality Agreement.
 
     (b) No investigation pursuant to this Section 5.04 shall affect any
representations or warranties of the parties herein or the conditions to the
obligations of the parties hereto.
 
     SECTION 5.05. Reasonable Best Efforts. Upon the terms and subject to the
conditions set forth in this Agreement, each of the parties agrees to use its
reasonable best efforts to take, or cause to be taken, all actions, and to do,
or cause to be done, and to assist and cooperate with the other parties in
doing, all things necessary, proper or advisable to consummate and make
effective, in the most expeditious manner practicable, the Merger and the other
transactions contemplated by this Agreement. Parent, Sub and the Company will
use their reasonable best efforts and cooperate with one another (i) in promptly
determining whether any filings are required to be made or consents, approvals,
waivers, permits or authorizations are required to be obtained (or, which if not
obtained, would result in an event of default, termination or acceleration of
any agreement or any put right under any agreement) under any applicable law or
regulation or from any governmental authorities or third parties, including
parties to loan agreements or other debt instruments and including such
consents, approvals, waivers, permits or authorizations as may be required or
necessary to transfer any assets and related liabilities of the Company to the
Surviving Corporation in the Merger, in connection with the transactions
contemplated by this Agreement, including the Merger and the Stock Exchange
Agreement and (ii) in promptly making any such filings, in furnishing
information required in connection therewith and in timely seeking to obtain any
such consents, approvals, permits or authorizations. Parent and the Company
shall mutually cooperate in order to facilitate the achievement of the benefits
reasonably anticipated from the Merger. In connection with the legal opinions
referred to in Sections 6.02(c) and 6.03(c), Parent, Sub and the Company agree
to deliver letters of representation reasonable under the circumstances as to
their present intention and present knowledge.
 
     SECTION 5.06. Benefit Plans. (a) Effective as of the Closing, Parent shall
provide that all retained employees of the Company and its subsidiaries, who are
not subject to collective bargaining agreements, shall participate in the
Company's existing employee benefit plans or, at the option of the Parent, to
participate in the employee benefit plans and arrangements of Parent (other than
those plans that are the subject of collective bargaining) on a basis no less
favorable in the aggregate than similarly situated employees of Parent and its
subsidiaries and, with respect to employees who are the subject of collective
bargaining agreements, all benefits and other terms and conditions of employment
shall be provided in accordance with the applicable collective bargaining
agreement; provided, however, that for purposes of the foregoing, no Stock Plan
or other plan, program or arrangement related to the stock of the Company or its
subsidiaries shall be considered nor shall Parent or any affiliate thereof have
any obligation to issue or provide any benefits related to the stock of the
Company or its subsidiaries, other than as provided in Section 2.02. In the
event that any employee of the Company or its affiliates is transferred to the
Parent or any affiliate of Parent or becomes a participant in an employee
benefit plan, program or arrangement maintained by or contributed by the
Surviving Corporation or its affiliates, Parent shall cause such plan, program
or arrangement to treat the prior service of such employee with the Company or
its affiliates, to the extent such prior service is recognized under the
comparable plan,
 
                                      A-25
 
<PAGE>

<PAGE>
program or arrangement of the Company, as service rendered to the Surviving
Corporation or its affiliate, as the case may be; provided, however, that Parent
may cause a reduction of benefits under any such plans, programs or arrangements
to the extent necessary to avoid duplication of benefits with respect to the
same covered matter or years of service and with respect to any defined benefit
pension plan of Parent or any affiliate of Parent, no such prior service shall
be recognized for any purposes other than eligibility to participate or vesting
of benefits.
 
     (b) To the extent that retained employees of the Company and its
subsidiaries become eligible to participate in plans sponsored by Parent and its
subsidiaries (other than Company Benefit Plans), Parent shall (i) waive all
limitations as to preexisting condition exclusions and waiting periods with
respect to participation and coverage requirements applicable to such employees
and their respective dependents under any welfare benefit plans that such
employees and dependents may be eligible to participate in, effective on or
after the Closing Date, but only to the extent that such exclusions and waiting
periods were inapplicable or satisfied under the analogous Company Benefit Plan;
and (ii) provide each such employee or dependent with credit for any co-payments
and deductibles paid prior to the Closing Date in respect of the plan year in
progress at the time such participation begins in satisfying any applicable
co-payment, deductible or out-of-pocket requirement under any analogous welfare
plans that such employees or dependents are eligible to participate in on or
after the Closing Date, but only to the extent such co-payment, deductible or
out-of-pocket requirements would be deemed satisfied under the analogous Company
Benefit Plan.
 
     SECTION 5.07. Indemnification. (a) Commencing at the Effective Time of the
Merger and for six years thereafter, the Surviving Corporation shall indemnify
all present and former directors or officers of the Company and its subsidiaries
for acts or omissions occurring prior to the Effective Time of the Merger to the
fullest extent now provided in their respective certificate of incorporation or
by-laws, provided such indemnification is consistent with applicable law, to the
extent such acts or omissions are uninsured (provided, that to the extent that
during any period insurance does not fully indemnify any person contemplated to
be indemnified in accordance with the first sentence of this Section 5.07, the
Surviving Corporation shall indemnify such person in accordance with such terms;
and, provided further, that to the extent that the Surviving Corporation's
insurance is not sufficient to fully indemnify any such person, Parent shall,
during such period, provided such indemnification is consistent with applicable
law, indemnify such person to the same extent as provided in the Company's
current certificate of incorporation and by-laws). For six years after the
Effective Time of the Merger, Parent shall also indemnify the Sellers (together
with all present and former directors of the Company and its subsidiaries, the
'indemnified parties') for all claims asserted by other stockholders of the
Company, including derivative lawsuits, costs of defense, settlement, judgment
and other amounts, in connection with the transactions contemplated by this
Agreement and the Stock Exchange Agreement alleging any breach of fiduciary duty
on the part of the Stockholder as a result of the transactions contemplated by
the Exchange Agreement, to the extent such indemnification is consistent with
applicable law.
 
     (b) Parent will cause to be maintained for a period of not less than six
years from the Effective Time of the Merger the Company's current directors' and
officers' insurance and indemnification policy (or at Parent's option a
replacement policy having terms no less advantageous than the Company's current
policy) to the extent that it provides coverage for events occurring prior to
the Effective Time of the Merger for all persons who are or were directors and
officers of the Company on the date of this Agreement, so long as the annual
premium therefor would not be in excess of 150% of the last annual premium paid
prior to the date of this Agreement (150% of such premium, the 'Maximum
Premium'). If the existing D&O Insurance expires, is terminated or cancelled
during such six-year period, Parent will use reasonable efforts to cause to be
obtained as much D&O Insurance as can be obtained for the remainder of such
period for an annualized premium not in excess of the Maximum Premium, on terms
and conditions no less advantageous than the existing D&O Insurance. The Company
represents to Parent that the Maximum Premium is $567,400.
 
     (c) Each indemnified party shall, promptly after receipt of notice of a
claim or action against such indemnified party in respect of which indemnity may
be sought thereunder, notify the Surviving Corporation or the Parent, as the
case may be (each an 'indemnifying party') in writing of the claim or action. If
any such claim or action shall be brought against an indemnified party, and it
shall have
 
                                      A-26
 
<PAGE>

<PAGE>
notified the indemnifying party thereof, unless based on the written advice of
counsel to such indemnified party, a conflict of interest between such
indemnified party and indemnifying parties may exist in respect of such claim,
the indemnifying party shall be entitled to participate therein, and, to the
extent that it wishes, jointly with any other similarly notified indemnifying
party, to assume the defense thereof. After notice from the indemnifying party
to the indemnified party of its election to assume the defense of such claim or
action, the indemnifying party shall not be liable to the indemnified party
under this Section 5.07 for any legal or other expenses subsequently incurred by
the indemnified party in connection with defense thereof. Any indemnifying party
against whom indemnity may be sought under this Section 5.07 shall not be liable
to indemnify an indemnified party if such indemnified party settles such claim
or action without the consent of the indemnifying party. The indemnifying party
may not agree to any settlement of any such claim or action, other than solely
for monetary damages for which the indemnifying party shall be responsible
hereunder, as a result of which any remedy or relief shall be applied to or
against the indemnified party, without the prior written consent of the
indemnified party, which consent shall not be unreasonably withheld. In any
action hereunder as to which the indemnifying party has assumed the defense
thereof, the indemnified party shall continue to be entitled to participate in
the defense thereof, with counsel of its own choice, but the indemnifying party
shall not be obligated hereunder to reimburse the indemnified party of the costs
thereof.
 
     SECTION 5.08. Expenses.
 
     (a) Except as set forth in this Section 5.08, all fees and expenses
incurred in connection with this Agreement, the Stock Exchange Agreement and the
transactions contemplated hereby and thereby shall be paid by the party
incurring such expenses, whether or not the Merger is consummated; provided,
however, that Parent and the Company shall share equally all fees and expenses,
other than accountants' and attorneys' fees, incurred in connection with the
printing and filing of the Joint Proxy Statement (including any preliminary
materials related thereto) and the Form S-4 (including financial statements and
exhibits) and any amendments or supplements thereto.
 
     (b) The Company shall pay Parent a fee of $12,500,000 (the 'Fee'), plus
actual, documented and reasonable out-of-pocket expenses of Parent relating to
the transactions contemplated by this Agreement not in excess of $3,000,000 in
the aggregate (including reasonable fees and expenses of Parent's counsel,
accountants and financial advisers) ('Expenses'), upon the termination of this
Agreement pursuant to Section 7.01(f) or (g).
 
     (c) The Company shall pay Parent the Fee plus the Expenses if and when all
of the following events have occurred:
 
          (i) an Alternative Transaction (as defined in Section 7.01) is
     publicly commenced, publicly disclosed, publicly proposed or publicly
     communicated to the Company at any time on or after the date of this
     Agreement and on or prior to the date of the Company Stockholder Meeting
     (including the last date on which any adjourned session thereof is
     reconvened);
 
          (ii) either Parent or the Company terminates this Agreement pursuant
     to Section 7.01(c) or Parent terminates this Agreement pursuant to Section
     7.01(d) if, in the case of termination under either such Section, the
     requisite vote for approval and adoption of the Merger Agreement by the
     stockholders of the Company shall not have been obtained by June 30, 1998;
     and
 
          (iii) thereafter on or prior to the second anniversary of the date of
     termination, (A) such Alternative Transaction is consummated or (B) there
     is consummated any other Alternative Transaction, whether or not commenced,
     publicly disclosed, publicly proposed or communicated to the Company prior
     to such termination.
 
     (d) The Company shall pay Parent the Fee plus the Expenses if and when both
of the following events have occurred:
 
          (i) Parent terminates this Agreement pursuant to Section 7.01(i) prior
     to the closing of the Exchange; and
 
          (ii) thereafter on or prior to the second anniversary of the date of
     termination, there is consummated any Alternative Transaction, whether or
     not commenced, publicly disclosed, publicly proposed or communicated to the
     Company prior to such termination.
 
                                      A-27
 
<PAGE>

<PAGE>
     (e) The Fee and Expenses payable pursuant to Section 5.08(b) shall be paid
(i) with respect to a termination pursuant to Section 7.01(f), within one
business day after such termination and (ii) with respect to a termination
pursuant to Section 7.01(g), simultaneously with and as a condition to such
termination. The Fee and Expenses payable pursuant to Section 5.08(c) or 5.08(d)
shall be paid within one business day following the consummation of the
Alternative Transaction referred to in such Section.
 
     (f) All transfer, documentary, sales, use, registration, stock transfer
Taxes and other such Taxes (including all applicable real estate transfer or
gains Taxes) and related fees (including any penalties, interest and additions
to Tax) incurred in connection with this Agreement and the transactions
contemplated hereby, including the Exchange, shall be paid by the Company and
the Company shall timely make all filings, returns, reports and forms as may be
required to comply with the provisions of such Tax laws.
 
     SECTION 5.09. Public Announcements. Parent and Sub, on the one hand, and
the Company, on the other hand, will consult with each other before holding any
press conferences or analyst calls and before issuing any press releases. The
parties will provide each other the opportunity to review and comment upon any
press release with respect to the transactions contemplated by this Agreement
and the Stock Exchange Agreement, including the Merger, and shall not issue any
such press release prior to such consultation, except as may be required by
applicable law, court process or by obligations pursuant to any listing
agreement with any national securities exchange. The parties agree that the
initial press release or releases to be issued with respect to the transactions
contemplated by this Agreement shall be mutually agreed upon prior to the
issuance thereof.
 
     SECTION 5.10. Affiliates. Prior to the Closing Date, the Company shall
deliver to Parent a letter identifying all persons who are, at the time this
Agreement is submitted for approval to the stockholders of the Company,
'affiliates' of the Company for purposes of Rule 145 under the Securities Act.
The Company shall deliver to Parent with respect to each such 'affiliate' on or
prior to the Closing a written agreement substantially in the form attached as
Exhibit A hereto.
 
     SECTION 5.11. Stock Exchange Listing. Parent shall use its reasonable best
efforts to cause the shares of Parent Class A Common Stock to be issued in the
Merger and under the Stock Plans to be approved for listing on the NYSE, subject
to official notice of issuance, prior to the Closing Date.
 
     SECTION 5.12. Certain Provisions. The Company shall not take, and shall not
permit any of its affiliates to take, any action which would require or permit,
or could reasonably be expected to require or permit, the Company or any other
person or entity to treat Parent or Sub, in acting pursuant to and as permitted
by this Agreement or the Stock Exchange Agreement, as an 'interested
stockholder' with whom the Company is prevented for any period pursuant to
Section 203 of the DGCL from engaging in any 'business combination' (as defined
in Section 203 of the DGCL) or take any action (including any charter or by-law
amendment) that has the effect of rendering Section 203 of the DGCL applicable
to Parent or any of its subsidiaries. The Company shall not, and shall not
permit any of its affiliates to, announce or disclose the Company's or such
affiliate's intention to take any such action or to treat Parent or Sub as such
an 'interested stockholder.' In the event that there shall be instituted or
pending any action or proceeding before any Governmental Entity to which the
Company is a party claiming or seeking a determination, directly or indirectly,
that the Company is prevented for any period pursuant to Section 203 of the DGCL
from engaging in any 'business combination' with Parent or Sub, the Company
shall take the position that the Company is not so prevented. The Company shall,
upon the request of Parent, take all reasonable steps to assist in any challenge
by Parent or Sub to the validity or applicability to the transactions
contemplated by this Agreement, including the Merger, the Stock Exchange
Agreement or the transactions contemplated by any of the foregoing, of any state
law.
 
     SECTION 5.13. No Solicitation.
 
     (a) The Company shall not, directly or indirectly, through any officer,
director, employee, representative or agent of the Company or any of its
subsidiaries or otherwise, (i) solicit, initiate or encourage any inquiries,
offers or proposals, or any indications of interest, regarding any merger, sale
of substantial assets, sale of shares of capital stock (including by way of a
tender offer) or similar transactions involving the Company or any significant
subsidiary of the Company other than the Merger
 
                                      A-28
 
<PAGE>

<PAGE>
(any of the foregoing inquiries or proposals being referred to herein as an
'Acquisition Proposal') or (ii) participate in negotiations or discussions
concerning, or provide any nonpublic information to any person relating to, any
Acquisition Proposal; provided, however, that, prior to the consummation of the
Exchange, the Company may participate in negotiations or discussions with, and
provide nonpublic information to, any person concerning an Acquisition Proposal
submitted in writing by such person to the Board of Directors of the Company
after the date of this Agreement if (A) such Acquisition Proposal was not
solicited, initiated or encouraged in violation of this Agreement, (B) the Board
of Directors of the Company, in its good faith judgment, believes that such
Acquisition Proposal is reasonably likely to result in an Alternative
Transaction that would be more favorable to the Company's stockholders than the
Merger or this Agreement and (C) failing to take such action would constitute a
breach of the Board's fiduciary duties under applicable law. Nothing contained
in this Section 5.13 shall prohibit the Board of Directors of the Company from
complying with Rule 14e-2 promulgated under the Exchange Act with regard to a
tender or exchange offer; provided that the Board shall not recommend that the
stockholders of the Company tender or exchange any shares of Company Common
Stock in connection with such tender or exchange offer unless failing to take
such action would constitute a breach of the Board's fiduciary duties under
applicable law.
 
     (b) The Company shall notify Parent as promptly as practicable if any
Acquisition Proposal is made and shall in such notice indicate in reasonable
detail the identity of the person making such Acquisition Proposal and the terms
and conditions of such Acquisition Proposal and shall keep Parent promptly
advised of all developments which could reasonably be expected to culminate in
the Board of Directors withdrawing, modifying or amending its recommendation of
the Merger and the other transactions contemplated by this Agreement.
 
     (c) If, pursuant to the proviso to Section 5.13(a)(ii), the Company
provides nonpublic information to any person who makes an Acquisition Proposal,
the Company shall require such person to enter into a confidentiality agreement
substantially similar to the Confidentiality Agreement as a condition to and
before providing any such information.
 
     (d) The Company shall immediately cease and cause to be terminated any
existing discussions or negotiations with any persons (other than Parent and
Sub) conducted heretofore with respect to any Acquisition Proposal. The Company
agrees not to release (by waiver or otherwise) any third party from the
provisions of any confidentiality or standstill agreement to which the Company
is a party.
 
     (e) The Company shall ensure that the officers, directors and employees of
the Company and its subsidiaries and any investment banker or other advisor or
representative retained by the Company are aware of the restrictions described
in this Section 5.13.
 
     SECTION 5.14. Board of Directors. In the event the Exchange is consummated
pursuant to the Stock Exchange Agreement prior to the Effective Time of the
Merger, Parent shall from and after such closing of the Exchange, be entitled to
designate, at its option, upon notice to the Company, up to that number of
directors, rounded up to the nearest whole number, of the Company's Board of
Directors, subject to compliance with Section 14(f) of the Exchange Act, as will
make the percentage of the Company's directors designated by Parent equal to the
greater of (i) the majority of the Company's Board of Directors and (ii) the
aggregate voting power of the shares of Company Common Stock held by Parent or
any of its subsidiaries as a percentage of the total voting power outstanding.
Parent shall determine for the approval of the Board of Directors the classes
into which such directors are placed, so long as such placement does not violate
or conflict with the Company's Certificate of Incorporation or By-laws or the
DGCL and the Company shall cause Parent's designees to be so placed. In the
event that Parent's designees are elected or appointed to the Board of Directors
of the Company, such Board of Directors shall have, until the Effective Time of
the Merger, at least one director who is a director of the Company prior to the
closing of the Exchange (the 'Continuing Director'); provided, however, that if
no Continuing Director remains, the other directors shall designate an
individual to fill such vacancy who shall not be an officer, director, employee
or affiliate of Parent or any of its affiliates and shall otherwise be an
'independent director' under the rules of the NYSE (such designee to be deemed
to be a Continuing Director for purposes of this Agreement). To the fullest
extent permitted by applicable law, the Company shall take all actions requested
by Parent which are reasonably necessary to effect the appointment or election
of the designees of Parent to the Board of Directors, including mailing the
 
                                      A-29
 
<PAGE>

<PAGE>
information required by Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder promptly following the date hereof in order to permit
designees of Parent to serve on the Board of Directors of the Company
immediately upon consummation of the Exchange (provided that Parent shall have
provided to the Company on a timely basis all information required to be
included with respect to Parent designees). In connection with the foregoing,
the Company will promptly either increase the size of the Company's Board of
Directors and/or obtain the resignation of such number of its current directors
as is necessary to enable Parent's designees to be elected or appointed to the
Company's Board of Directors as provided above and shall cause the appointment
of Parent's designees to fill such vacancies or newly created directorships
effective upon the closing of the Exchange. Following the election or
appointment of Parent's designees pursuant to this Section 5.14(a) and prior to
the Effective Time, any termination or amendment of this Agreement by the
Company, any extension by the Company of the time for the performance of any of
the obligations or other acts of Parent or waiver or assertion of any of the
Company's rights hereunder, or any other consents or actions by the Board of
Directors with respect to this Agreement, will require the concurrence of a
majority of the Continuing Directors.
 
     SECTION 5.15. Certain Agreements. Neither the Company nor any subsidiary of
the Company will waive or fail to enforce any provision of any confidentiality
or standstill or similar agreement to which it is a party without the prior
written consent of Parent.
 
     SECTION 5.16. Stop Transfer. The Company acknowledges and agrees to be
bound by and comply with the provisions of Section 12 of the Stock Exchange
Agreement as if a party thereto with respect to transfers of record ownership of
shares of Company Common Stock, and agrees to notify the transfer agent for any
shares of Company Common Stock or voting rights certificates and provide such
documentation and do such other things as may be necessary to effectuate the
provisions of such agreement.
 
     SECTION 5.17. Officer's Certificate. The Company, at the request of Parent,
shall deliver a certificate to Parent executed by the chief executive officer
and the chief financial officer of the Company in the form and with respect to
the matters referred to in Section 6.4 of the Stock Exchange Agreement dated as
of the date of the closing of the Exchange, or, alternatively, inform Parent
that it is unable to give such certificate because of the inaccuracy of the
matters that would otherwise be set forth therein.
 
     SECTION 5.18. Parent to Vote in Favor of Merger. Parent agrees that it will
vote (or cause to be voted) all shares of Company Common Stock owned by it or
its subsidiaries at the time of the Company Stockholder Meeting in favor of the
approval and adoption of the Merger Agreement.
 
     SECTION 5.19. Anti-Dilution. The Company will as promptly as practicable
notify Parent if it issues any shares of Company Common Stock, whether upon the
exercise, exchange or conversion of securities exercisable or exchangeable for
or convertible into shares of Company Common Stock, or otherwise. If the

     to the Effective Time of the Merger); or
 
          (d) by Parent, if any required approval of the stockholders of the

     required vote upon a vote held at a duly held meeting of stockholders or at
     any adjournment thereof; or
 
          (e) by the Company, if any required approval of the stockholders of

     Alternative Transaction (A) that the Board of Directors of the Company
     determines in its good faith judgment is more favorable to the Company's
     stockholders than this Agreement and the Merger and (B) as a result of

     upon the advice of outside counsel, that it is obligated by its fiduciary
     obligations under applicable law to terminate this Agreement, provided that

     other transactions contemplated herein and which shall not have been cured
     prior to the date 10 business days following notice of such breach; or
 
          (i) by Parent, if, prior to the closing of the Exchange, there shall
     have been a breach of any covenant or agreement on the part of the Company

     adverse effect with respect to the Company or which materially adversely
     affects (or materially delays) the consummation of the Merger or any of the
     other transactions contemplated herein and which shall not have been cured
     prior to the date 10 business days following notice of such breach; or

          (j) by the Company, if the Board of Directors of Parent shall
     withdraw, modify or change its approval or recommendation of this Agreement

     or shall have resolved to do so.
 
     As used herein, 'Alternative Transaction' means any of (i) a transaction or

covenants or agreements set forth in this Agreement.
 
     SECTION 7.03. Amendment. Subject to Section 5.14, any provision of this
Agreement may be amended or waived prior to the Effective Time of the Merger
(whether before or after approval of matters presented in connection with the
Merger by the stockholders of the Company or Parent) if, and only if, such
amendment or waiver is in writing and signed, in the case of an amendment, by
the Company and Parent or, in the case of a waiver, by the party against whom
the waiver is to be effective; provided that after the adoption of this
Agreement by the stockholders of (i) the Company, there shall be made no
amendment that by law requires further approval by the stockholders of the
Company without the further approval of such stockholders and (ii) Parent, there

any such extension or waiver shall be valid only if set forth in an instrument
in writing signed on behalf of such party. The failure of any party to this
Agreement to assert any of its rights under this Agreement or otherwise shall
not constitute a waiver of such rights.
 
     SECTION 7.05. Procedure for Termination, Amendment, Extension or Waiver. A
termination of this Agreement pursuant to Section 7.01, an amendment of this
Agreement pursuant to Section 7.03 or an extension or waiver pursuant to Section

the case of Parent, Sub or the Company, action by its Board of Directors or the
duly authorized designee of its Board of Directors.

                        FORM OF COMPANY AFFILIATE LETTER
 
Gentlemen:
 
     The undersigned, a holder of shares of Common Stock, par value $.01 per
share ('Company Common Stock'), of Designer Holdings Ltd., a Delaware
corporation (the 'Company'), is entitled to receive in connection with the
merger (the 'Merger') of the Company with WAC Acquisition Corporation, a
Delaware corporation, securities (the 'Parent Securities') of The Warnaco Group,
Inc. ('Parent'). The undersigned acknowledges that the undersigned may be deemed
an 'affiliate' of the Company within the meaning of Rule 145 ('Rule 145')
promulgated under the Securities Act of 1933, as amended (the 'Act'), although
nothing contained herein should be construed as an admission of such fact.
 
     If in fact the undersigned were an affiliate under the Act, the
undersigned's ability to sell, assign or transfer the Parent Securities received
by the undersigned in exchange for any shares of Company Stock pursuant to the
Merger may be restricted unless such transaction is registered under the Act or
an exemption from such registration is available. The undersigned understands
that such exemptions are limited and the undersigned has obtained advice of
counsel as to the nature and conditions of such exemptions, including
information with respect to the applicability to the sale of such securities of
Rules 144 and 145(d) promulgated under the Act.
 
     The undersigned hereby represents to and covenants with the Company that
the undersigned will not sell, assign or transfer any of the Parent Securities
received by the undersigned in exchange for shares of Company Stock pursuant to
the Merger except (i) pursuant to an effective registration statement under the
Act, (ii) in conformity with the volume and other limitations of Rule 145 or
(iii) in a transaction which, in the opinion of independent counsel reasonably
satisfactory to Parent or as described in a 'no-action' or interpretive letter
from the Staff of the Securities and Exchange Commission (the 'SEC'), is not
required to be registered under the Act.
 
     In the event of a sale or other disposition by the undersigned of Parent
Securities pursuant to Rule 145, the undersigned will supply Parent with
evidence of compliance with such Rule, in the form of a letter in the form of
Annex I hereto. The undersigned understands that Parent may instruct its
transfer agent to withhold the transfer of any Parent Securities disposed of by
the undersigned, but that upon receipt of such evidence of compliance the
transfer agent shall effectuate the transfer of the Parent Securities sold as
indicated in the letter.
 
     The undersigned acknowledges and agrees that appropriate legends will be
placed on certificates representing Parent Securities received by the
undersigned in the Merger or held by a transferee thereof, which legends will be
removed by delivery of substitute certificates upon receipt of an opinion in
form and substance reasonably satisfactory to Parent from independent counsel
reasonably satisfactory to Parent to the effect that such legends are no longer
required for purposes of the Act.
 
     The undersigned acknowledges that (i) the undersigned has carefully read
this letter and understands the requirements hereof and the limitations imposed
upon the distribution, sale, transfer or other disposition of Parent Securities
and (ii) the receipt by Parent of this letter is an inducement and a condition
to Parent's obligations to consummate the Merger.
 
                                          Very truly yours,
 
Dated:

                                                                    TO EXHIBIT A
 
[Name]                                  [Date]
 
     On                         the undersigned sold the securities
('Securities') of The Warnaco Group, Inc. (the 'Company') described below in the
space provided for that purpose (the 'Securities'). The Securities were received
by the undersigned in connection with the merger of WAC Acquisition Corporation
with and into Designer Holdings Ltd.
 
     Based upon the most recent report or statement filed by the Company with
the Securities and Exchange Commission, the Securities sold by the undersigned
were within the prescribed limitations set forth in paragraph (e) of Rule 144
promulgated under the Securities Act of 1933, as amended (the 'Act').
 
     The undersigned hereby represents that the Securities were sold in
'brokers' transactions' within the meaning of Section 4(4) of the Act or in
transactions directly with a 'market maker' as that term is defined in Section
3(a)(38) of the Securities Exchange Act of 1934, as amended. The undersigned
further represents that the undersigned has not solicited or arranged for the
solicitation of orders to buy the Securities, and that the undersigned has not
made any payment in connection with the offer or sale of the Securities to any
person other than to the broker who executed the order in respect of such sale.
 
                                          Very truly yours,
 
              [Space to be provided for description of securities]

                                                                         ANNEX B
 
                            STOCK EXCHANGE AGREEMENT
 
     STOCK EXCHANGE AGREEMENT dated as of September 25, 1997 among THE WARNACO
GROUP, INC., a Delaware corporation ('Parent'), NEW RIO, L.L.C., a Delaware
limited liability company (the 'Stockholder'), and each of the members of
Stockholder signatory hereto (each, a 'Member').
 
     WHEREAS, concurrently herewith, Parent, WAC Acquisition Corporation, a
Delaware corporation and a wholly owned subsidiary of Parent ('Sub'), and
Designer Holdings Ltd., a Delaware corporation (the 'Company'), are entering
into an Agreement and Plan of Merger (as such agreement may be amended from time
to time and whether or not such agreement has been terminated, the 'Merger
Agreement'; capitalized terms used but not defined herein shall have the
meanings set forth in the Merger Agreement) pursuant to which Sub or, at the
election of Parent, a direct wholly owned subsidiary of Parent other than Sub
will be merged with and into the Company (the 'Merger'), whereby each share of
Common Stock, each having a par value of one cent ($0.01), of the Company
('Company Common Stock') issued and outstanding immediately prior to the
Effective Time of the Merger will be converted into the right to receive a
fraction of a share of Class A Common Stock, par value $0.01 per share, of
Parent ('Parent Class A Common Stock'), other than shares of Company Common
Stock owned, directly or indirectly, by the Company or any subsidiary of the
Company or by Parent, Sub or any other subsidiary of Parent.
 
     WHEREAS, as a condition to their willingness to enter into the Merger
Agreement, Parent and Sub have required that the Stockholder and the Members
(collectively, the 'Sellers') enter into, and the Stockholder and the Members
have agreed to enter into, this Agreement pursuant to which, among other things,
regardless of any termination of the Merger Agreement, Parent and the Sellers
have agreed to exchange shares of Parent Class A Common Stock for all the shares
of Company Common Stock owned by the Sellers on the terms herein set forth,
which in the aggregate constitute a majority of the outstanding Company Common
Stock.
 
     WHEREAS, for Federal income tax purposes, it is intended that, so long as
the Merger occurs, the exchange of Parent Class A Common Stock for Company
Common Stock pursuant to this Agreement and the Merger pursuant to the Merger
Agreement qualify as a reorganization under the provisions of Section 368 of the
Internal Revenue Code of 1986, as amended.
 
     NOW, THEREFORE, in consideration of the representations, warranties,
covenants and agreements contained in this Agreement, the parties agree as
follows:
 
1. EXCHANGE TRANSACTION
 
     1.1 Exchange. On the terms and subject to the conditions set forth in this
Agreement, the Stockholder agrees to transfer 16,483,868 shares of Company
Common Stock, all of which are owned by the Stockholder and which represent all
of the shares of Company Common Stock owned by the Sellers (the 'Shares'), to
Parent, free and clear of any mortgage, pledge, lien, security interest, claim
or other encumbrance (each, a 'Lien') or Restriction created by any Member or by
the Stockholder or otherwise binding upon the Shares, and Parent agrees to issue
to the Stockholder, in exchange for the Shares, shares of Parent Class A Common
Stock in accordance with Section 1.2 below, free and clear of any Lien or
Restriction except as contemplated by this Agreement or any letter entered into
for tax purposes relating to restrictions on selling Exchange Shares (a 'Lock-Up
Letter'). For purposes of this Agreement, 'Restriction' means, when used with
respect to any specified security, any stockholders or other trust agreement,
option, warrant, escrow, proxy, buy-sell agreement, power of attorney or other
contract, agreement or arrangement which (i) grants to any person the right to
sell or otherwise dispose of or vote such specified security or any interest
therein, or (ii) restricts the transfer of, or the exercise of any rights or the
enjoyment of any benefits arising by reason of, the ownership of such specified
security.
 
     1.2 Exchange Ratio. For each Share transferred to Parent pursuant to this
Agreement, the Stockholder shall receive .324 of a fully paid and nonassessable
share of Parent Class A Common Stock (the 'Exchange Ratio'). In the event that
the aggregate number of shares of Parent Class A Common
 
                                      B-1
 
<PAGE>

<PAGE>
Stock to be issued to the Stockholder, based on the Exchange Ratio, would result
in the issuance by Parent of a fractional share of Parent Class A Common Stock,
such fractional share shall be rounded to the nearest whole share. The total
number of shares of Parent Class A Common Stock to be issued to the Stockholder
hereunder are referred to herein as the 'Exchange Shares.'
 
2. CLOSING
 
     The closing (the 'Closing') of the Exchange shall take place on the second
business day following satisfaction or waiver of the conditions set forth in
Sections 6 and 7, or such other date and time as the parties shall otherwise
agree to. The date of the Closing is referred to herein as the 'Closing Date'.
The Closing will take place at 10:00 a.m. on the Closing Date, at the offices of
Simpson Thacher & Bartlett, 425 Lexington Avenue, New York, New York 10017. At
the Closing, (i) the Stockholder shall deliver to Parent certificate(s)
representing all of the Shares, duly endorsed for transfer to Parent, and (ii)
Parent shall deliver to the Stockholder a stock certificate representing the
Exchange Shares.
 
3. REPRESENTATIONS AND WARRANTIES OF THE MEMBERS
 
     Each Member, severally with respect to himself, herself or itself (as the
case may be) and the Shares which are 'Allocated Shares' of such Member under
the Third Amended and Restated Limited Liability Company Agreement of the
Stockholder (the 'LLC Agreement') makes the following representations and
warranties to Parent.
 
     3.1 Power; Binding Agreement. Such Member has the legal capacity (in the
case of individual Members), power and authority to enter into and perform all
of such Member's obligations under this Agreement. Such Member is the legal and
valid owner of, and has good and valid title to, its interest in the
Stockholder. Such Member's allocable interest in the total number of shares of
Company Common Stock owned by the Stockholder is set forth on Schedule 3.2. The
execution, delivery and performance of this Agreement by such Member will not
violate any other agreement to which such Member is a party (including any trust
agreement, voting agreement, stockholders agreement or voting trust) except to
the extent that any such violations, individually or in the aggregate, could not
reasonably be expected to have a material adverse effect on Parent or to prevent
or materially delay the consummation of the transactions contemplated hereby.
This Agreement has been duly and validly executed and delivered by such Member
and constitutes a valid and binding agreement of such Member, enforceable
against such Member in accordance with its terms. There is no beneficiary or
holder of a voting trust certificate or other interest of any trust of which a
Member is Trustee whose consent is required for the execution and delivery of
this Agreement or the consummation of the transactions contemplated hereby. If
such Member is married and such Member's Allocated Shares constitute community
property, this Agreement has been duly authorized, executed and delivered by,
and constitutes a valid and binding agreement of, such Member's spouse,
enforceable against such person in accordance with its terms.
 
     3.2 No Conflict. Other than filings required under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the 'HSR Act'), and the filing
of Forms 4 and Schedules 13D under the Securities and Exchange Act of 1934, as
amended, and the rules and regulations thereunder (the 'Exchange Act'), no
filing with, and no permit, authorization, consent or approval of, any state or
federal public body or authority is necessary for the execution of this
Agreement by such Member and the consummation by such Member of the transactions
contemplated hereby, except for such filings the failure of which to be made,
individually or in the aggregate, could not reasonably be expected to have a
material adverse effect on Parent or to prevent or materially delay the
consummation of the transactions contemplated hereby. Neither the execution and
delivery of this Agreement by such Member nor the consummation by such Member of
the transactions contemplated hereby nor compliance by such Member with any of
the provisions hereof shall (x) conflict with or result in any breach of any
applicable trust or other organizational documents applicable to such Member,
(y) result in a violation or breach of, or constitute (with or without notice or
lapse of time or both) a default (or give rise to any third party right of
termination, cancellation, material modification or acceleration) under any of
the terms, conditions or provisions of any note, bond, mortgage, indenture,
license, contract, commitment, arrangement, understanding, agreement or other
instrument or obligation of any kind to which such Member is a party or by which
such Member or any of such Member's properties or
 
                                      B-2
 
<PAGE>

<PAGE>
assets may be bound or (z) violate any order, writ, injunction, decree,
judgment, order, statute, rule or regulation applicable to such Member or any of
such Member's properties or assets, except to the extent any of the foregoing,
individually or in the aggregate, could not reasonably be expected to have a
material adverse effect on Parent or to prevent or materially delay the
consummation of the transactions contemplated hereby.
 
     3.3 Reliance. Such Member understands and acknowledges that Parent is
entering into, and causing Sub to enter into, the Merger Agreement in reliance
upon such Member's execution and delivery of this Agreement.
 
     3.4 No Broker. Such Member has not employed any investment banker, broker,
finder, consultant or intermediary in connection with the transactions
contemplated by this Agreement which would be entitled to any investment
banking, brokerage, finder's or similar fee or commission in connection with
this Agreement or the transactions contemplated hereby.
 
     3.5 Transfer Instruction. Each Member has instructed the Stockholder, in
accordance with Section 11.1(c) of the LLC Agreement, to transfer its Allocated
Shares to Parent and the Stockholder has provided Parent with true and accurate
proof thereof.
 
     3.6 Voting Instruction. Each of the Member Managers (as defined in the LLC
Agreement) has determined and advised the Stockholder, in accordance with
Section 4.2(b) of the LLC Agreement, that in the event the Exchange has not
occurred by the time of the Company Stockholder Meeting, the Stockholder shall
vote the Shares in favor of the Merger as set forth in Section 9.3.
 
4. REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDER
 
     The Stockholder makes the following representations and warranties to the
Parent:
 
     4.1 Power; Binding Agreement. The Stockholder has the power and authority
to enter into and perform all of its obligations under this Agreement (including
the power and authority without further action on the part of the Members to
consummate the Exchange and comply with the voting requirements of Section 9.3).
The execution, delivery and performance of this Agreement by the Stockholder
will not violate any other agreement to which the Stockholder is a party
(including any trust agreement, voting agreement, stockholders agreement or
voting trust), except to the extent any such violations, individually or in the
aggregate, could not reasonably be expected to have a material adverse effect on
Parent or to prevent or materially delay the consummation of the transactions
contemplated hereby. This Agreement has been duly and validly authorized,
executed and delivered by the Stockholder and constitutes a valid and binding
agreement of the Stockholder, enforceable against it in accordance with its
terms. The Members constitute all the members of the Stockholder.
 
     4.2 No Conflict. Other than filings required under the HSR Act, and the
filing of Forms 4 and Schedules 13D under the Exchange Act, no filing with, and
no permit, authorization, consent or approval of, any state or federal public
body or authority is necessary for the execution of this Agreement by the
Stockholder and the consummation by the Stockholder of the transactions
contemplated hereby, except for any such filings the failure of which to be
made, individually or in the aggregate, could not reasonably be expected to have
a material adverse effect on Parent or to prevent or materially delay the
consummation of the transactions contemplated hereby. Neither the execution and
delivery of this Agreement by the Stockholder nor the consummation by the
Stockholder of the transactions contemplated hereby nor compliance by the
Stockholder with any of the provisions hereof shall (x) conflict with or result
in any breach of the LLC Agreement, (y) result in a violation or breach of, or
constitute (with or without notice or lapse of time or both) a default (or give
rise to any third party right of termination, cancellation, material
modification or acceleration) under any of the terms, conditions or provisions
of any note, bond, mortgage, indenture, license, contract, commitment,
arrangement, understanding, agreement or other instrument or obligation of any
kind to which the Stockholder is a party or by which the Stockholder or any of
the Stockholder's properties or assets may be bound or (z) violate any order,
writ, injunction, decree, judgment, order, statute, rule or regulation
applicable to the Stockholder or any of the Stockholder's properties or assets,
except to the extent any of the foregoing, individually or in the aggregate,
could not reasonably be expected to have a material
 
                                      B-3
 
<PAGE>

<PAGE>
adverse effect on Parent or to prevent or materially delay the consummation of
the transactions contemplated hereby.
 
     4.3 Reliance. The Stockholder understands and acknowledges that Parent is
entering into, and causing Sub to enter into, the Merger Agreement in reliance
upon the Stockholder's execution and delivery of this Agreement.
 
     4.4 Ownership of Shares. The Stockholder is the record owner of 16,483,868
Shares, which constitute a majority of the outstanding shares of Company Common
Stock. The Stockholder has, and at the Closing will have, good and valid title
to the Shares, free and clear of any Liens or Restrictions and it has the full
legal right, power and authority to assign, transfer and deliver such Shares to
Parent pursuant hereto. The Stockholder has sole voting power, and sole power of
disposition, with respect to all of the Shares.
 
     4.5 No Broker. The Stockholder has not employed any investment banker,
broker, finder, consultant or intermediary in connection with the transactions
contemplated by this Agreement or the Merger Agreement which would be entitled
to any investment banking, brokerage, finder's or similar fee or commission in
connection with this Agreement or the transactions contemplated hereby.
 
     4.6 Purchase for Investment. The Stockholder is acquiring the Exchange
Shares for its own account as principal for investment and not with a view to
resale or distribution or with any present intention of distribution or selling
the same. The Stockholder is fully aware that such shares of Parent Class A
Common Stock have not been registered under the Securities Act or under any
applicable state securities laws, and are being offered and sold in reliance on
exemptions from the registration requirements of the Securities Act and all such
laws. The Stockholder is an 'accredited investor' as such term is defined in
Regulation D promulgated under the Securities Act. The Stockholder is able to
bear the economic risk of the investment in such shares of Parent Class A Common
Stock and has such knowledge and experience in financial and business matters,
and knowledge of the business of Parent, as to be capable of evaluating the
merits and risks of a prospective investment. The Stockholder acknowledges that
it has received or been given access to financial information and other
documents and records necessary to make a well-informed investment decision and
has had an opportunity to discuss Parent's business, management and financial
affairs with Parent's management.
 
     4.7 Limitations on Transferability. In addition to the restrictions set
forth in Section 9.7 and in the Lock-Up Letter, the Stockholder acknowledges
that it may not transfer any of the shares of Parent Class A Common Stock in the
Exchange unless and until the same are registered under the Securities Act and
any applicable state securities laws, or unless an exemption from such
registration is available and that it may transfer such shares of Parent Class A
Common Stock only in accordance with this Agreement.
 
     4.8 Legend. Each document or certificate evidencing any shares of Parent
Class A Common Stock issued in the Exchange shall be stamped or imprinted with
legends substantially as follows:
 
          (a) 'The shares of Common Stock, par value $0.01 per share, of The
     Warnaco Group, Inc. (the 'Company') represented by this certificate have
     not been registered under the Securities Act of 1933, as amended, or under
     the securities laws of any state; and may not be sold, assigned,
     transferred, pledged or otherwise disposed of except in compliance with, or
     pursuant to an exemption from, the requirements of such Act or such laws.'
 
          (b) 'The shares of Common Stock, par value $0.01 per share, of The
     Warnaco Group, Inc. (the 'Company') represented by this certificate are
     subject to restrictions on transfer contained in a Stock Exchange Agreement
     dated as of September 25, 1997, as amended from time to time, a copy of
     which is on file at the principal office of the Company.'
 
Parent will exchange certificates without one or both of the foregoing legends
for certificates with one or both of the foregoing legends upon the request of
the Stockholder as follows: (i) in the case of clause (a), upon such time as the
holder thereof may sell such shares without registration of such sale under the
Securities Act, as evidenced by an opinion of counsel to such holder; and (ii)
in the case of clause (b), upon the later to occur of (x) upon the termination
of the restricted period contained in any Lock-Up Letter to which the holder of
such Shares is subject and (y) otherwise, upon the Release Date.

     5.1 Power; Binding Agreement. Parent has the power and authority to enter
into and perform all of its obligations under this Agreement. The execution,
delivery and performance of this Agreement by Parent will not violate any other
agreement to which Parent is a party (including any trust agreement, voting
agreement, stockholders agreement or voting trust), except to the extent that
any such violations, individually or in the aggregate, could not reasonably be
expected to have a material adverse effect on Parent or to prevent or materially
delay the consummation of the transactions contemplated hereby. This Agreement

with its terms.

third party right of termination, cancellation, material modification or
acceleration) under any of the terms, conditions or provisions of any note,
bond, mortgage, indenture, license, contract, commitment, arrangement,
understanding, agreement or other instrument or obligation of any kind to which

be bound or (z) violate any order, writ, injunction, decree, judgment, order,
statute, rule or regulation applicable to Parent or any of Parent's properties
or assets, except to the extent that any of the foregoing, individually or in
the aggregate, could not reasonably be expected to have a material adverse
effect on Parent or to prevent or materially delay the consummation of the
transactions contemplated hereby.
 
6. CONDITIONS TO OBLIGATIONS OF PARENT
 
     Unless waived, in whole or in part, in writing by Parent, the obligations
of Parent to consummate the Exchange and to perform any and all of its
postclosing obligations shall be subject to the satisfaction at or prior to the
Closing Date of each of the following conditions (it being understood that any
termination of the Merger Agreement, including pursuant to Sections 7.01(f), (g)

third parties as are necessary in connection with the transactions contemplated
hereby have been obtained, except such licenses, permits, consents, approvals,

7. CONDITIONS TO OBLIGATIONS OF THE STOCKHOLDER AND THE MEMBERS
 
     Unless waived, in whole or in part, in writing by the Stockholder, the
obligations of the Stockholder and the Members to consummate the Exchange as
contemplated by this Agreement shall be subject to the fulfillment prior to or
on the Closing Date of each of the following conditions (it being understood
that any termination of the Merger Agreement, including pursuant to Sections

permanent injunction or other order issued by any court of competent
jurisdiction or other legal restraint or prohibition enjoining or preventing the
consummation of the Exchange shall be in effect.

8. COVENANTS OF PARENT
 
     Parent hereby covenants and agrees as follows:
 
     8.1 Filings and Other Actions. As promptly as practicable after the
execution of this Agreement, Parent shall file notification reports under the
HSR Act and shall request early termination of the waiting period under the HSR
Act and use its reasonable best efforts to obtain clearance or authorization
under the HSR Act for the Merger and the Exchange at the earliest practicable
time. Parent agrees to cooperate fully with the Stockholder to promptly
effectuate the filing of any notification required under the HSR Act.
 
     8.2 Reasonable Best Efforts. Subject to the terms and conditions of this
Agreement and the Merger Agreement, Parent agrees to use its reasonable best
efforts to take, or cause to be taken, all actions, and
 
                                      B-7
 
<PAGE>

<PAGE>
to do, or cause to be done, all things necessary, proper or advisable to
consummate and make effective the transactions contemplated by this Agreement
and the Merger Agreement. Parent hereby agrees, while this Agreement is in
effect, and except as contemplated hereby, not to intentionally and knowingly
take any action with the intention and knowledge that such action would make any
of its representations or warranties contained herein untrue or incorrect in any
material respect or have the effect of preventing or disabling it from
performing its obligations under this Agreement.
 
     8.3 Registration Statement. (a) Shelf Registration. Parent will use its
reasonable best efforts to file and have declared effective as promptly as
practicable following the Release Date a registration statement (a 'Shelf
Registration') under the Securities Act, on an appropriate form, for the resale
of the shares of Parent Class A Common Stock issued to the Stockholder in the
Exchange and not subject to a Lock-Up Letter. In connection therewith Parent
agrees to use its reasonable best efforts to make such other filings as are
necessary for sales under such Shelf Registration to be made in accordance with
any state securities or 'blue sky' laws, provided, however, that Parent shall
not be required to consent to service of process in any jurisdiction in which it
is not now subject in connection therewith. Such registration statement shall
include all shares of Parent Class A Common Stock issued to the Stockholder and
not subject to a Lock-Up Letter, and may include securities of Parent for sale
for Parent's own account. Upon the request of the Stockholder, following the
termination of any Lock-Up Letter, Parent will use its reasonable best efforts
to add to the Shelf Registration Exchange Shares that had been subject to any
such Lock-Up Letter. The Stockholder shall promptly provide Parent with such
information as it reasonably requests to include in such registration statement
with respect to the Stockholder and the Members. Notwithstanding anything else
contained in this agreement, Parent shall be obligated to keep such Registration
Statement effective only until the earliest of (i) 24 months after the closing
date for the Merger, (ii) such time as all shares of Parent Class A Common Stock
covered by such Registration Statement have been sold or disposed of and (iii)
such time as all such securities are freely tradeable.
 
     (b) Delays. Notwithstanding any another provision of this Agreement to the
contrary, if at any time while the Shelf Registration is effective Parent
provides written notice to the Stockholder that in its good faith and reasonable
judgment it would be materially disadvantageous to Parent (because the sale of
shares of Parent Class A Common Stock covered by such registration statement
('Registrable Securities') or the disclosure of information therein or in any
related prospectus or prospectus supplement would materially interfere with any
acquisition, financing or other material event or transaction in connection with
which a registration of securities under the Securities Act for the account of
Parent is then intended or the public disclosure of which at the time would be
materially prejudicial to Parent) (a 'Disadvantageous Condition') for sales of
Registrable Securities thereunder to then be permitted, and setting forth the
general reasons for such judgment, Parent may refrain from maintaining current
the prospectus contained in the Shelf Registration until such Disadvantageous
Condition no longer exists (notice of which Parent shall promptly deliver to the
Stockholder); provided, however, that (i) upon delivery by the Stockholder of a
certificate stating that any Seller desires to sell Registrable Securities in
order for the Stockholder, its Members or the direct or indirect owners of its
Members to pay taxes due as a result of the failure of the Exchange to be
treated as a tax-free reorganization, so long as, in the good faith judgment of
Parent, the sale of Registrable Securities at such time would not be reasonably
likely to cause Parent to be in violation of Federal securities laws absent
additional disclosure by Parent, Parent shall forgo or rescind its delivery of a
notice of Disadvantageous Condition in such instance and shall use its
reasonable best efforts to ensure that a prospectus is available for such sales;
and (ii) in the event such notice of Disadvantageous Condition is in connection
with an offering of securities in connection with which Parent has retained an
investment bank, Parent shall certify to the Stockholder that such investment
bank has advised Parent that such notice is reasonably necessary in connection
with such offering. Upon the receipt by the Stockholder of any such notice of a
Disadvantageous Condition (i) the Stockholder shall notify the Members and the
Sellers shall forthwith discontinue use of the prospectus and any prospectus
supplement under such registration statement and shall suspend sales of
Registrable Securities until such Disadvantageous Condition no longer exists and
(ii) if so directed by Parent by notice as aforesaid the Stockholder will
deliver to Parent all copies, other than permanent file copies then in the
Stockholder's possession, of the prospectus and prospectus supplements then
covering such Registrable Securities at the time of receipt of such notice as
aforesaid.
 
                                      B-8
 
<PAGE>

<PAGE>
Notwithstanding anything else contained in this Agreement, the maintaining
current of a prospectus (and the suspension of sales of Registrable Securities)
in connection with the Shelf Registration may not be delayed under this
paragraph (b) for more than a total of 60 days in any six-month period.
 
     (c) Expenses. Except as provided herein, Parent shall pay all registration
expenses with respect to the Shelf Registration. Notwithstanding the foregoing,
(i) the Sellers and Parent shall each be responsible for their own internal
administrative and similar costs, (ii) the Sellers shall be responsible for the
legal fees and expenses of their own counsel and (iii) the Sellers shall be
responsible for all underwriting discounts and commissions, selling or placement
agent or broker fees and commissions, and transfer taxes, if any, in connection
with the sale of securities by the Sellers.
 
     (d) Indemnification and Contribution. (i) Parent agrees to indemnify and
hold harmless each of the Sellers and each person, if any, who controls each
Seller within the meaning of either Section 15 of the Securities Act or Section
20 of the Exchange Act from and against any and all losses, claims, damages and
liabilities (including, without limitation, any legal or other expenses
reasonably incurred in connection with defending or investigating any such
action or claim) insofar as such losses, claims, damages or liabilities are
caused by any untrue statement or alleged untrue statement of a material fact
contained in any registration statement or any amendment thereof, any
preliminary prospectus or prospectus (as amended or supplemented if Parent shall
have furnished any amendments or supplements thereto) relating to the
Registrable Securities, or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, except insofar as such losses, claims,
damages or liabilities are caused by any such untrue statement or omission or
alleged untrue statement or omission based upon information furnished to Parent
in writing by the Sellers expressly for use therein. Parent also agrees to
indemnify any underwriter of the Registrable Securities so offered and each
person, if any, who controls such underwriter on substantially the same basis as
that of the indemnification by Parent of the Sellers provided in this Section
8.3(d).
 
     (ii) Each Seller agrees to indemnify and hold harmless Parent, its
directors, the officers who sign any registration statement and each person, if
any who controls Parent within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act, from and against any and all
losses, claims, damages and liabilities (including, without limitation, any
legal or other expenses reasonably incurred in connection with defending or
investigation any such action or claim) insofar as such losses, claims, damages
or liabilities are caused by any untrue statement or alleged untrue statement of
a material fact contained in any registration statement or any amendment
thereof, any preliminary prospectus or prospectus (as amended or supplemented if
Parent shall have furnished any amendments or supplements thereto) relating to
the Registrable Securities, or caused by any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, but only with reference to information
furnished in writing by such Seller (or any representative thereof) expressly
for use in a registration statement, any preliminary prospectus, prospectus or
any amendments or supplements thereto. Each Seller also agrees to indemnify any
underwriter of the Registrable Securities so offered and each person, if any,
who controls such underwriter on substantially the same basis as that of the
indemnification by the Sellers of Parent provided in this Section 8.3(d).
 
     (iii) Each party indemnified under paragraph (i) or (ii) above shall,
promptly after receipt of notice of a claim or action against such indemnified
party in respect of which indemnity may be sought thereunder, notify the
indemnifying party in writing of the claim or action, provided that the failure
to notify the indemnifying party shall not relieve it from any liability that it
may have to an indemnified party on account of the indemnity agreement contained
in paragraph (i) or (ii) above except to the extent that the indemnifying party
was actually prejudiced by such failure, and in no event shall such failure
relieve the indemnifying party from any other liability that it may have to such
indemnified party. If any such claim or action shall be brought against an
indemnified party, and it shall have notified the indemnifying party thereof,
unless based on the written advice of counsel to such indemnified party of
conflict of interest between such indemnified party and indemnifying parties may
exist in respect of such claim, the indemnifying party shall be entitled to
participate therein, and, to the extent that it wishes, jointly with any other
similarly notified indemnifying party, to assume the defense thereof. After
notice
 
                                      B-9
 
<PAGE>

<PAGE>
from the indemnifying party to the indemnified party of its election to assume
the defense of such claim or action, the indemnifying party shall not be liable
to the indemnified party under this section 8.3(d)(iii) for any legal or other
expenses subsequently incurred by the indemnified party in connection with
defense thereof. Any indemnifying party against whom indemnity may be sought
under this Section 8.3 shall not be liable to indemnify an indemnified party if
such indemnified party settles such claim or action without the consent of the
indemnifying party. The indemnifying party may not agree to any settlement of
any such claim or action, other than solely for monetary damages for which the
indemnifying party shall be responsible hereunder, the result of which any
remedy or relief shall be applied to or against the indemnified party, without
the prior written consent of the indemnified party, which consent shall not be
unreasonably withheld. In any action hereunder as to which the indemnifying
party has assumed the defense thereof, the indemnified party shall continue to
be entitled to participate in the defense thereof, with counsel of its own
choice, but the indemnifying party shall not be obligated hereunder to reimburse
the indemnified party of the costs thereof.
 
     (iv) If the indemnification provided for in this Section 8.3(d) shall for
any reason be unavailable (other than in accordance with its terms) to an
indemnified party in respect of any loss, liability, cost, claim, or damage
referred to therein, then each indemnifying party shall, in lieu of indemnifying
such indemnified party, contribute to the amount paid or payable by such
indemnified party as a result such loss, liability, cost, claim or damage (A) in
such proportion as is appropriate to reflect the relative benefits received by
Parent on the one hand and the Sellers on the other hand from the offering of
the Registrable Securities or (B) if such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (A) above but also
the relative fault of the indemnifying party or parties on the one hand and of
the indemnified party or parties on the other hand in damages or liabilities, as
well as any other relevant equitable considerations. The relative benefits
received by Parent on the one hand and the Sellers on the other hand in
connection with the offering of the Registrable Securities shall be deemed to be
in the same respective proportions as the net proceeds from the offering of the
Registrable Securities (before deducing expenses) received by Parent and the
Sellers, respectively, bear to the aggregate public offering price of the
Registrable Securities. The relative fault of Parent on the one hand and the
Sellers on the other hand shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The amount paid or payable by an indemnified party as a
result of the loss, cost, claim, damage or liability, or action in respect
thereof, referred to above in this paragraph (iv) shall be deemed to include,
for purposes of this paragraph (iv), any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any such action or claim. Parent and the Stockholder agree that it would not be
just and equitable if contribution pursuant to this Section 8.3(d)(iv) were
determined by pro rata allocation or by any other method of allocation which
does not take account of the equitable considerations referred to in this
paragraph. Notwithstanding any other provision of this Section 8.3, the
Stockholder shall not be required to contribute any amount in excess of the
amount by which the total price at which the Registrable Securities of the
Sellers were offered to the public exceeds the amount of any damages which the
Stockholder has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission o alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.
 
     (e) Material Misstatements. Parent shall promptly notify the Stockholder in
writing (i) at any time when a prospectus relating to a registration pursuant to
Section 8.3(a) is required to be delivered under the Securities Act of the
happening of any event as a result of which the prospectus included in such
registration statement, as then in effect, includes an untrue statement of a
material fact or omits to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, and (ii) of any request by the SEC or any
other regulatory body or other body having jurisdiction for any amendment of or
supplement to any registration statement or other document relating to such
offering, and in either such case, at the request of the Stockholder prepare and
furnish to the Stockholder a reasonable number of copies of a supplement to or
an amendment of such prospectus as may be necessary so that, as thereafter
delivered
 
                                      B-10
 
<PAGE>

<PAGE>
to the purchasers of Registrable Securities, such prospectus shall not include
an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein, in light of
the circumstances under which they are made, not misleading.
 
9. COVENANTS OF THE STOCKHOLDER AND THE MEMBERS
 
     The Sellers, jointly and severally, hereby covenant and agree as follows:

cause to be taken, all actions, and to do, or cause to be done, all things
necessary, proper or advisable to consummate and make effective the transactions
provided for by this Agreement. Each Seller hereby agrees, while this Agreement
is in effect, and except as contemplated hereby, not to intentionally and
knowingly take any action with the intention and knowledge that such action
would make any of its representations or warranties contained herein untrue or
incorrect in any material respect or have the effect of preventing or disabling
it from performing its obligations under this Agreement.
 
     9.3 Voting. The Stockholder hereby agrees that, during the time this
Agreement is in effect, at any meeting of the stockholders of the Company (or at

sought, the Stockholder shall vote (or cause to be voted) the Shares (i) in
favor of the Merger, the adoption of the Merger Agreement and the approval of
the terms thereof and each of the other transactions and other matters
contemplated by the Merger Agreement and this Agreement and any actions required

or warranty or any other obligation or agreement of the Company under the Merger
Agreement; (iii) except as otherwise agreed to in writing in advance by Parent,
against the following actions (other than the Merger and the transactions and
other matters contemplated by the Merger Agreement): (1) any extraordinary
corporate transaction, such as a merger, consolidation or other business
combination involving the Company or its subsidiaries; (2) a sale, lease or
transfer of a material amount of assets of the Company or its subsidiaries or a

business; or (d) any other action; which, in the case of each of the matters
referred to in clauses 3(a), (b), (c) or (d), is intended, or could reasonably
be expected, to impede, frustrate, prevent, interfere with, delay, postpone,
discourage or materially adversely affect the contemplated economic benefits to
Parent of the Exchange or the Merger or the transactions contemplated by the
Merger Agreement and this Agreement or change in any manner the voting rights of
the Company Common Stock. The Stockholder shall not enter into any agreement or
understanding with any person or entity prior to the termination of this
Agreement to vote or give instructions after such termination in a manner
inconsistent with clauses (i), (ii) or (iii) of the preceding sentence.
 
     9.4 Proxy. The Stockholder hereby grants to, and appoints, Parent and Linda
J. Wachner, Chief Executive Officer of Parent, William S. Finkelstein, Chief
Financial Officer of Parent, and Stanley P. Silverstein, Vice President, General
Counsel and Secretary of Parent, in their respective capacities as officers of
Parent, and any individual who shall hereafter succeed to any such office of
Parent, and any other designee of Parent, each of them individually, its
irrevocable proxy and attorney-in-fact (with full power of substitution) to vote
the Shares as indicated in Section 9.3. The Stockholder intends this proxy to be
irrevocable and coupled with an interest and will take such further action and
execute such other instruments as may be necessary to effectuate the intent of
this proxy and hereby revokes any proxy previously granted by it with respect to
its Shares.
 
     9.5 No Solicitation. During the term of this Agreement, the Sellers shall
not, directly or indirectly, through any officer, director, employee,
representative or agent of the Sellers or any of its subsidiaries
 
                                      B-11

or otherwise, (i) solicit, initiate or encourage any inquiries, offers or
proposals, or any indications of interest, regarding any merger, sale of
substantial assets, sale of shares of capital stock (including by way of a
tender offer) or similar transactions involving the Sellers or any significant
subsidiary of the Sellers other than the Merger or (ii) participate in
negotiations or discussions concerning, or provide any nonpublic information to
any person relating to, any Acquisition Proposal. If any of the Sellers receives
any such inquiry or proposal, then such Seller shall promptly inform Parent of
the terms and conditions, if any, of such inquiry or proposal and the identity
of the person making it. Each Seller will immediately cease and cause to be
terminated any existing activities, discussions or negotiations with any parties
conducted heretofore with respect to any of the foregoing.
 
     9.6 Restriction on Transfer of Shares, Proxies and Non-Interference;
Restriction on Withdrawal. No Seller shall, directly or indirectly: (i) except
pursuant to or as contemplated hereby by the terms of this Agreement or the
Merger Agreement, offer for sale, sell (including short sales), transfer,
tender, pledge, encumber, assign or otherwise dispose of (including by gift) or
enter into any contract, option or other arrangement or understanding (including
any profit-sharing arrangement) with respect to or consent to the offer for
sale, sale, transfer, tender, pledge, encumbrance, assignment or other
disposition of, any or all of the Shares or any interest therein; (ii) except as
contemplated hereby, grant any proxies or powers of attorney, deposit any Shares
into a voting trust or enter into any other voting arrangement with respect to
any Shares; or (iii) take any action that would make any representation or

that they shall not, directly or indirectly, offer, sell, transfer, tender,
pledge or encumber, assign or otherwise dispose of any shares of Parent Class A
Common Stock (a) until the earlier of (i) such time at or after the Effective
Time of the Merger that is no earlier than the time when holders of Company
Common Stock can sell the shares of Parent Class A Common Stock issued pursuant
to the Merger (without giving effect to any restrictions under applicable
securities laws) and (ii) the termination of the Merger Agreement in accordance
with its terms (the date on which such earlier time occurs, the 'Release Date'),
(b) other than in accordance with Section 4.7 and (c) other than in accordance
with the terms of any Lock-Up Letter.
 
     9.8 Transfer Taxes. All transfer, documentary, sales, use, registration,

Stockholder shall timely make all filings, returns, reports and forms as may be
required to comply with the provisions of such Tax laws.
 
     9.9 Waiver of Dividend. The Sellers hereby irrevocably waive their right to
receive with respect to the Exchange Shares, and hereby instruct Parent not to
pay to the Sellers in respect of the Exchange Shares, any dividend declared by
the Board of Directors of Parent payable to holders of record of Parent as of a
record date prior to the Effective Time of the Merger.
 
     9.10 Standstill. Each Seller agrees that such Seller shall not (a) acting
alone or in concert with others, seek to affect or influence the control of the
management or board of directors of Parent or the business, operations or
policies of Parent; (b) deposit any shares of Parent Class A Common Stock or
securities exercisable or exchangeable or convertible into shares of Parent
Class A Common Stock, or other securities having the right to vote generally
with shares of Parent Class A Common Stock (collectively 'Parent Voting
Securities') in a voting trust or subject any Parent Voting Securities to any
proxy, arrangement or agreement with respect to the voting of such Parent Voting
Securities or other agreement having similar effect; (c) initiate or propose any
stockholder proposal or make, or in any way, participate in, directly or
indirectly, any 'solicitation' of 'proxies' to vote, other than in connection
with the Merger and the Merger Agreement, or intentionally seek in an organized
fashion to influence any person with respect to the voting of, any Parent Voting
Securities in a manner inconsistent with the position of the board of directors
of Parent or become 'participant' in a 'solicitation' (as such terms are defined
in Regulation 14A under the Exchange Act, as in effect on the date hereof) in
opposition to
 
                                      B-12
 
<PAGE>

<PAGE>
the recommendation of the majority of the directors of Parent with respect to
any matter; (d) join a partnership, limited partnership, syndicate or other
group, or otherwise act in concert with any other person, for the purpose of
acquiring, holding, voting or disposing of Parent Voting Securities, or,
otherwise become a 'person' within the meaning of Section 13(d)(3) of the
Exchange Act relating to any of the matters set forth in clauses (a), (b) or
(c); or (e) take any other action inconsistent with this Section 9.10. The
provisions of this Section 9.10 shall not apply to any Seller following such
time after the Exchange as such Seller cease to beneficially own at least 25% of
the Exchange Shares acquired by such Seller in the Exchange.
 
     9.11 Amendment of LLC Agreement. By the execution and delivery of this
Agreement, each Member hereby agrees that, effective as of the Closing Date,
Sections 11.2 and 11.3 of the LLC Agreement shall be deemed amended to delete
the terms thereof in their entirety. To the extent any provision of Article XI
of the LLC Agreement conflicts with the terms of this Agreement, the terms of
this Agreement shall be controlling.
 
     9.12 Transfer of Shares to Michael A. Covino. Notwithstanding anything to
the contrary contained in this Agreement, simultaneously with or promptly
following the execution hereof by Michael A. Covino ('Covino'), the Stockholder
shall transfer (the 'Covino Transfer') the 225,374 Shares (the 'Covino Shares')
which are the 'Allocated Shares' of Covino to Covino. From and after such time
as the Covino Transfer shall have been completed, (i) Covino shall, with respect
to the Covino Shares, be fully subject to and shall comply with and be entitled
to the benefits of all of the covenants and agreements contained herein and
applicable to the Stockholder, including, without limitation, the
representations set forth in Sections 4.4 and 4.6, the requirement to exchange
the Covino Shares at Closing, free and clear of Liens or Restrictions, in
accordance with Section 1 and to comply with the voting and proxy requirements
of Sections 9.3 and 9.4, respectively; (ii) no representation of the Members
shall be deemed to be breached to the extent it is no longer true solely as a
result of the Covino Transfer; (iii) Covino shall make the representation in the
last sentence of Section 3.1 in his capacity as 'Stockholder'; and (iv) in order
to effectuate the foregoing, references herein and in the Merger Agreement to
the 'Stockholder' shall be deemed to refer to Covino and the Stockholder. Covino
shall, notwithstanding the Covino Transfer, continue to be treated as a Member
for purposes of the representations and warranties of the Members set forth in
Section 3 (other than Section 3.5) and as a Seller for all purposes hereof.
 
10. FURTHER ASSURANCES
 
     From time to time, at the other party's request and without further
consideration, each party hereto shall execute and deliver such additional
documents and take all such further action as may be necessary or desirable to
consummate and make effective, in the most expeditious manner practicable, the
transactions contemplated by this Agreement.
 
11. CERTAIN EVENTS
 
     The Stockholder agrees that this Agreement and the obligations hereunder
shall attach to the Stockholder's Shares and shall be binding upon any person or
entity to which legal or beneficial ownership of such Shares shall pass, whether
by operation of law or otherwise, including without limitation the Stockholder's
administrators, successors or receivers.
 
12. STOP TRANSFER
 
     The Stockholder agrees with, and covenants to, Parent that it shall not
request that the Company register the transfer (book-entry or otherwise) of any
certificate or uncertificated interest representing any of the Shares, unless
such transfer is made in compliance with this Agreement and the Lock-Up Letter.
The Stockholder agrees, with respect to any Shares in certificated form, that
immediately following the execution hereof, it will present to the Company, the
certificates representing the Shares and the Company will inscribe upon such
certificates the following legend: 'The shares of Common Stock, par value $.01
per share, of Designer Holdings Ltd. (the 'Company') represented by this
certificate are subject to a Stock Exchange Agreement dated as of September 25,
1997, and may not be
 
                                      B-13
 
<PAGE>

<PAGE>
sold or otherwise transferred, except in accordance therewith. Copies of such
Agreement may be obtained at the principal executive offices of the Company.'
The Stockholder agrees that it will no longer hold any Shares, whether
certificated or uncertificated, in 'street name' or in the name of any nominee.
Pursuant to the Merger Agreement, the Company has agreed to notify the transfer
agent for any Shares in uncertificated form of the provisions set forth in this
Section 12 and has agreed to, and the Stockholder agrees to, provide such
documentation and to do such other things as may be required to give effect to
such provisions with respect to such uncertificated Shares. Following the
Closing for the Exchange, Parent will not register the transfer (book-entry or
otherwise) of any certificate or uncertificated interest representing the
Stockholder's Parent Class A Common Stock, unless such transfer is made in
compliance with this Agreement.
 
13. POST-CLOSING COVENANTS; TERMINATION
 
     13.1 Termination. If the Closing of the Exchange shall not have occurred on
or prior to June 30, 1998, other than as a result of a material breach of this
Agreement by any party hereto, the Stockholder or Parent may terminate this
Agreement without liability. If the Closing Date shall not have occurred on or
prior to such date as a result of material breach of any representation,
warranty, covenant or obligation by the Sellers (or any of them), on the one
hand, or Parent on the other, the non-breaching party shall have the right to
terminate this Agreement without liability. Except for Sections 3.1, 3.5, 4.1,
4.4 and 4.6, the representations and warranties of the parties set forth herein
shall terminate upon the Closing of the Exchange.
 
     13.2 Noncompetition. (a) Each of Charterhouse Equity Partners II, L.P.
('CEP') and Arnold H. Simon (the 'Partners') severally agrees that, commencing
on the Closing Date until the second anniversary of the Closing Date, it will
not, and, as to Mr. Simon, he will cause his affiliates not to, in North
America, South America and Central America, directly or indirectly, invest in
(other than a passive equity investment constituting no more than 5% of the
equity of the subject company), engage in, become financially interested in, or
be employed by, whether as an employee, consultant, partner, principal, agent,
representative or Stockholder or in any other corporate or representative
capacity, if it involves engaging in, or rendering services that are integral to
the business of or advice pertaining to, any lines of business Parent was
actively conducting on the date of this Agreement or the date of consummation of
the Exchange, except in connection with an agreement consented to in writing by
Parent, or, in the case of CEP, in connection with its investments existing on
the date of this Agreement, nor will the Partners solicit any business of the
type conducted by the Company from any customer of the Company or hire any
employee of the Company or any of its subsidiaries (or any of their successors)
except, as to Mr. Simon, as he is permitted under his letter agreement of
employment between him and Parent and any subsequent letter agreement or
arrangement approved in writing by Parent; provided, however, that the foregoing
shall not prohibit Debra Simon from being employed by, whether as an employee,
consultant or representative, or acting in any other corporate or representative
capacity to, any entity involved in any of such lines of business.
 
     (b) It is the intention of the parties that if any of the restrictions or
covenants contained herein is held to cover a geographic area or to be for a
length of time that is not permitted by applicable law, or in any way construed
to be too broad or to any extent invalid, such provision shall not be construed
to be null, void and of no effect, but to the extent such provision would be
valid or enforceable under applicable law, a court of competent jurisdiction
shall construe and interpret or reform this Section 13.2 to provide for a
covenant having the maximum enforceable geographic area, time period and other
provisions (not greater than those contained herein) as shall be valid and
enforceable under such applicable law. Each of the Partners acknowledges that
any breach of the terms, conditions or covenants set forth in this Section 13.2
shall be competitively unfair and may cause irreparable damage to Parent because
of the special, unique, unusual, extraordinary and intellectual character of the
Company's business, and Parent's recovery of damages at law will not be an
adequate remedy. Accordingly, each of the Partners agrees that for any breach of
the terms, covenants or agreements of this Section 13.2, a restraining order or
an injunction or both may be issued against such person, in addition to any
other rights or remedies Parent may have.

     (c) Each Seller agrees to hold in strict confidence all data and
information relating to the business of the Company and its subsidiaries (the
'Proprietary Information') obtained in the course of its ownership of shares or
participation in the management of the Company or any of its subsidiaries or
otherwise which is either non-public, confidential or proprietary in nature.
Each Seller agrees that subject to any requirement of law or tribunal order, it
will keep such Proprietary Information confidential and will not, without the
prior written consent of Parent, be disclosed by any Seller to any person. This
Agreement shall be inoperative as to such portions of the Proprietary
Information which (i) are or become generally available to the public other than
as a result of a disclosure by Parent or any of its Representatives, (ii) become
available to any Seller or one of its Representatives on a nonconfidential basis
from a source other than any of Parent or any of its Representatives, which has
not advised such Seller that it is bound by a confidentiality agreement with, or
other contractual, legal or fiduciary obligation of confidentiality to, any of
Parent or any of its subsidiaries or affiliates with respect to such portions of
the Proprietary Information, or (iii) were known by any Seller on a
nonconfidential basis prior to its commencement of employment with, or ownership
of, the Company or one of its subsidiaries. The Sellers agree that Parent shall
be entitled to equitable relief, including injunction and specific performance,
in the event of any breach of the provisions of this Section 13.2. Such remedies
shall not be deemed to be the exclusive remedies for a breach of this Section
13.2 by any Seller but shall be in addition to all other remedies available at
law or equity. It is further understood and agreed that failure or delay by
Parent in exercising any right, power or privilege under this Section 13.2 shall
not operate as a waiver thereof nor shall any single or partial exercise thereof
preclude and other or further exercise of any right, power or privilege under
this Agreement.
 
14. SURVIVAL OF REPRESENTATIONS AND WARRANTIES
 
     The representations and warranties of the parties contained herein shall
survive the Closing and the consummation of the transactions contemplated
hereby.
 
15. MISCELLANEOUS
 
     15.1 Successors and Assigns. This Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and
assigns. Other than as set forth in the immediately succeeding sentence, no
party may assign any of its rights, or delegate any of its duties or
obligations, hereunder without the prior written consent of the other party, and
any such purported assignment or delegation shall be void ab initio.
Notwithstanding the foregoing, Parent, its affiliates, and its successors and
assigns, may assign their rights and delegate their duties (i) to any successor
entity resulting from any liquidation, merger, consolidation' reorganization, or
transfer of all or substantially all of the assets or stock of Parent, or (ii)
to any affiliate of Parent; provided, that in either case, any such assignee
shall expressly assume all of the obligations Parent hereunder.

'Notices') given or made pursuant to this Agreement shall be in writing and

Any of the parties to this Agreement may from time to time change its address
for receiving notices by giving written notice thereof in the manner set forth
above.
 
     15.3 Amendment: Waiver. No provision of this Agreement may be waived unless
in writing signed by all of the parties to this Agreement, and the waiver of any
one provision of this Agreement shall not be deemed to be a waiver of any other
provision. This Agreement may be amended, supplemented or otherwise modified
only by a written agreement executed by all of the parties to this Agreement.
 
     15.4 Enforcement; Jurisdiction. The parties agree that irreparable damage
would occur in the event that any of the provisions of this Agreement were not
performed in accordance with their specific terms or were otherwise breached. It
is accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions of this Agreement in any Federal court located in the
State of Delaware or any Delaware state court, this being in addition to any
other remedy to which they are entitled at law or in equity. Any suit, action or
proceeding seeking to enforce any provision of, or based on any matter arising
out of or in connection with, this Agreement or the transactions contemplated by
this Agreement may be brought against any of the parties in any Federal court
located in the State of Delaware or any Delaware state court, and each of the
parties hereto hereby consents to the exclusive jurisdiction of such courts (and
of the appropriate appellate courts therefrom) in any such suit, action or
proceeding and waives any objection to venue laid therein. Process in any such
suit, action or proceeding may be served on any party anywhere in the world,
whether within or without the State of Delaware. Without limiting the generality
of the foregoing, each party hereto agrees that service of process upon such
party at the address referred to in Section 15.2, together with written notice
of such service to such party, shall be deemed effective service of process upon
such party.
 
     15.5 Severability. Whenever possible, each provision or portion of any
provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or unenforceable in
any respect under any applicable law or rule in any jurisdiction, such
invalidity, illegality or unenforceability will not affect any other provision
or portion of any provision in such jurisdiction, and this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision or portion of any provision had never been
contained herein.

     15.6 Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other parties.
 
     15.7 Entire Agreement; No Third-Party Beneficiaries. This Agreement and the
other agreements referred to herein constitute the entire agreement, and
supersede all prior agreements and understandings, both written and oral, among
the parties with respect to the subject matter of this Agreement. This Agreement
is not intended to confer upon any person other than the parties any rights or
remedies.
 
     15.8 Governing Law. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
 
     15.9 Headings. The section and subsection headings contained in this
Agreement are included for convenience only and form no part of the agreement
between the parties.
 
     15.10 Expenses. Each party shall pay its own costs, expenses, including
without limitation, the fees and expenses of their respective counsel and
financial advisors.
 
     15.11 Publicity. The initial press release relating to this Agreement shall
be a joint press release, and Parent and the Sellers shall use reasonable
efforts to agree upon the text of any other press release before issuing any
such press release.
 
     15.12 Specific Performance. Each of the parties hereto recognizes and
acknowledges that a breach by it of any covenants or agreements contained in
this Agreement will cause the other parties to sustain damages for which they
would not have an adequate remedy at law for money damages, and therefore each
of the parties hereto agrees that in the event of any such breach the aggrieved
party or parties shall be entitled to the remedy of specific performance of such
covenants and agreements and injunctive and other equitable relief, without the
posting of bond or other security, in addition to any other remedy to which it
or they may be entitled, at law or in equity.
 
     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
first above written.

                         OPINION OF LAZARD FRERES & CO. LLC
 
                                                              September 25, 1997
 
The Board of Directors
THE WARNACO GROUP, INC.
90 Park Avenue
New York, New York 10016
 
Dear Members of the Board:
 
     We understand that The Warnaco Group, Inc. (the 'Company') proposes to
enter into (i) a Stock Exchange Agreement (the 'Exchange Agreement') with New
Rio, L.L.C. ('New Rio') and each of the members thereof listed as signatories to
the Exchange Agreement, pursuant to which New Rio will exchange (the 'Exchange')
each of the shares of common stock, par value $0.01 per share (the 'Common
Stock'), of Designer Holdings Ltd. (the 'Subject Company') owned by it for the
right to receive 0.324 shares (the 'Exchange Ratio') of the Company's Class A
Common Stock, par value $0.01 per share (the 'Class A Common Stock'), and (ii)
an Agreement and Plan of Merger (the 'Merger Agreement') with the Subject
Company and WAC Acquisition Corporation, a wholly owned subsidiary of the
Company ('WAC'), pursuant to which each share of Common Stock outstanding
immediately prior to the effective time of the Merger referred to below, other
than any shares of Common Stock owned or held by the Company or the Subject
Company or any of their respective subsidiaries, will be converted into the
right to receive that number of shares of Class A Common Stock equal to the
Exchange Ratio. Pursuant to the Merger Agreement, WAC will be merged with and
into the Subject Company (the 'Merger').
 
     You have requested our opinion as to the fairness, from a financial point
of view, to the Company and its stockholders of the Exchange Ratio in connection
with the Exchange and the Merger, taken as a whole. In connection with this
opinion, we have:
 
          (1) Reviewed the financial terms and conditions of drafts of the
     Exchange Agreement and the Merger Agreement, each dated September 24, 1997;
 
          (2) Analyzed certain historical business and financial information
     relating to the Company and the Subject Company;
 
          (3) Reviewed the various financial forecasts and other data provided
     to us by the Company relating to its businesses and the benefits projected
     by the Company to be realized in connection with the Merger;
 
          (4) Reviewed the various financial forecasts and other data provided
     to us by the Company relating to the businesses of the Subject Company and
     by the Subject Company relating to its businesses (which included financial
     forecasts for the current and next fiscal years only, having been advised
     that the Subject Company has not prepared projections beyond such fiscal
     years);
 
          (5) Held discussions with members of senior management of each of the
     Company and the Subject Company with respect to the businesses and
     prospects of the Company and the Subject Company, respectively, the
     strategic objectives of each, and possible benefits that might be realized
     following the Merger;
 
          (6) Reviewed the public information with respect to certain other
     companies in lines of business we believe to be generally comparable to
     those of the Company and the Subject Company;
 
          (7) Reviewed the financial terms of certain business combinations
     involving companies in lines of business we believe to be generally
     comparable to those of the Company and the Subject Company, and in other
     industries generally;
 
          (8) Reviewed the historical stock prices of the Class A Common Stock
     and the Common Stock; and
 
                                      C-1
 
<PAGE>

<PAGE>
          (9) Conducted such other financial studies, analyses and
     investigations as we deemed appropriate.
 
     We have relied upon the accuracy and completeness of the foregoing
information and have not assumed any responsibility for any independent
verification of such information or any independent valuation or appraisal of
any of the assets or liabilities of the Company or the Subject Company. With
respect to financial forecasts, including the benefits projected to be realized
following the Exchange and the Merger, we have assumed that they have been
reasonably prepared on bases reflecting the best currently available estimates
and judgments of management of the Company and the Subject Company as to the
future financial performance of the Company and the Subject Company,
respectively. In that regard, such financial forecasts assume that the License
Agreement dated as of August 4, 1994, as amended, between Calvin Klein, Inc. and
a subsidiary of the Subject Company will remain in full force and effect for the
period covered by such forecasts. We assume no responsibility for and express no
view as to such forecasts or the assumptions on which they are based.
 
     Further, our opinion is necessarily based on economic, monetary, market and
other conditions as in effect on, and the information made available to us as
of, the date hereof.
 
     In rendering our opinion, we have assumed that, in all respects material to
our analysis, the Exchange and the Merger will be consummated on the terms
described in the Exchange Agreement and the Merger Agreement, respectively,
without any waiver of any material terms or conditions by the Company, and that
obtaining the necessary regulatory approvals for the Exchange and the Merger
will not have an adverse effect on the Company or the Subject Company and that
the projected benefits of the Exchange and the Merger are realized substantially
in accordance with such projections. We have also assumed that the definitive
Exchange Agreement and the Merger Agreement will not differ in any material
respect from the drafts thereof furnished to us.
 
     As you are aware, we were engaged by the Company as of September 19, 1997
for purposes of delivering this opinion to the Board of Directors of the
Company, and, as a result, we did not participate in the negotiation of the
Exchange Ratio or of any of the other terms of the Exchange or the Merger.
 
     Lazard Freres & Co. LLC has been engaged by the Company in connection with
this opinion and will receive a fee for our services upon delivery hereof. In
addition, the Company has agreed to indemnify us for certain liabilities that
may arise out of the rendering of this opinion.
 
     Our engagement and the opinion expressed herein are for the benefit of the
Company's Board of Directors and our opinion is rendered to the Company's Board
of Directors in connection with its consideration of the Exchange and the
Merger. This opinion is not intended to and does not constitute a recommendation
to any holder of the Class A Common Stock as to whether such stockholder should
vote for the Merger. It is understood that, except for the inclusion of this
letter in its entirety in a proxy statement to the stockholders of the Company,
this letter may not be disclosed or otherwise referred to without our prior
consent, except as may otherwise be required by law or by a court of competent
jurisdiction.
 
     Based on and subject to the foregoing, we are of the opinion that, as of
the date hereof, the Exchange Ratio in connection with the Exchange and the
Merger, taken as a whole, is fair to the Company and its stockholders from a
financial point of view.
 
                                          Very truly yours,
 
                                          LAZARD FRERES & CO. LLC

 
                                          By  /s/ Peter L. Smith

                            OPINION OF MERRILL LYNCH
 
                                                              September 25, 1997
 
Board of Directors
DESIGNER HOLDINGS LTD.
1385 Broadway
New York, NY 10018
 
Members of the Board of Directors:
 
     Designer Holdings Ltd. (the 'Company'), The Warnaco Group, Inc. (the
'Acquiror') and WAC Acquisition Corporation, a subsidiary of the Acquiror
('Sub'), propose to enter into an Agreement and Plan of Merger, dated as of
September 25, 1997 (the 'Agreement'), pursuant to which Sub will be merged with
and into the Company in a transaction (the 'Merger') in which each outstanding
share of the Company's common stock, par value $0.01 per share (the 'Company
Shares'), will be converted into the right to receive 0.324 (the 'Exchange
Ratio') of a share of Class A Common Stock, par value $0.01 per share, of the
Acquiror (the 'Acquiror Shares'). In addition, New Rio L.L.C. ('New Rio'),
certain members of New Rio, and the Acquiror propose to enter into a Stock
Exchange Agreement, dated as of September 25, 1997 (the 'Stock Exchange
Agreement'), pursuant to which New Rio will sell, and the Acquiror will
purchase, each of the Company Shares owned by New Rio (representing
approximately 51.3% of the outstanding Company Shares) in a transaction in which
each such Company Share will be exchanged for 0.324 of an Acquiror Share. We
understand the closing of the transaction contemplated by the Stock Exchange
Agreement is expected to occur prior to the effective time of the Merger and is
not subject to a vote of the stockholders of the Acquiror or the Company.
 
     You have asked us whether, in our opinion, the Exchange Ratio in the Merger
is fair from a financial point of view to the holders of the Company Shares
(other than the Acquiror and its affiliates and New Rio and its affiliates).
 
     In arriving at the opinion set forth below, we have, among other things:
 
          (1) Reviewed the Company's Initial Public Offering Prospectus, dated
     May 9, 1996, the Prospectus for the 6% Convertible Trust Originated
     Preferred Securities Offering, dated November 1, 1996, Annual Report, Form
     10-K and related financial information for the fiscal year ended December
     31, 1996 and the Company's Forms 10-Q and the related unaudited financial
     information for the quarterly periods ending March 31, 1997 and June 30,
     1997;
 
          (2) Reviewed the Acquiror's Prospectus for Class A Common Stock
     Offering, dated September 19, 1995, Annual Reports, Forms 10-K and related
     financial information for the three fiscal years ended January 4, 1997 and
     the Acquiror's Forms 10-Q and the related unaudited financial information
     for the quarterly periods ending April 5, 1997 and July 5, 1997;
 
          (3) Reviewed certain information, including financial forecasts,
     relating to the business, earnings, cash flow, assets, liabilities and
     prospects of the Company and the Acquiror, furnished to us or discussed
     with us by the Company and the Acquiror, respectively;
 
          (4) Conducted discussions with members of senior management of the
     Company and the Acquiror concerning their respective businesses and
     prospects, before and after giving effect to the Merger;
 
          (5) Reviewed the historical market prices and valuation multiples for
     the Company Shares and the Acquiror Shares and compared them with those of
     certain publicly traded companies that we deemed reasonably similar to the
     Company and the Acquiror, respectively;
 
                                      D-1
 
<PAGE>

<PAGE>
          (6) Reviewed certain financial information of the Company and the
     Acquiror and compared them with those of certain publicly traded companies
     that we deemed to be relevant;
 
          (7) Compared the proposed financial terms of the Merger with the
     financial terms of certain other transactions in the apparel industry
     specifically, of which we note there were a limited number which we deemed
     to be relevant, and in other industries generally;
 
          (8) Reviewed the potential pro forma impact of the Merger;
 
          (9) Reviewed drafts of the Agreement and the Stock Exchange Agreement,
     dated September 25, 1997, in the forms proposed to be entered into;
 
          (10) Reviewed such other financial studies and analyses and took into
     account such other matters as we deemed necessary, including our assessment
     of general economic, market and monetary conditions.
 
     In preparing our opinion, we have assumed and relied on the accuracy and
completeness of all information supplied or otherwise made available to us,
discussed with or reviewed by or for us, or publicly available, and we have not
assumed any responsibility for independently verifying such information or
undertaken an independent evaluation or appraisal of any of the assets or
liabilities of the Company or the Acquiror. In addition, we have not assumed any
obligation to conduct, nor have we conducted, any physical inspection of the
properties or facilities of the Company or the Acquiror. With respect to the
financial forecast information furnished to or discussed with us by the Company
or the Acquiror, we have assumed that they have been reasonably prepared and
reflect the best currently available estimates and judgment of the Company's or
the Acquiror's management as to the expected future financial performance of the
Company or the Acquiror, as the case may be. We have further assumed that the
Merger will qualify as a tax-free reorganization for U.S. federal income tax
purposes. We have also assumed that the final form of the Agreement and the
Stock Exchange Agreement will be in the forms of the last drafts reviewed by us.
 
     Our opinion is necessarily based upon market, economic and other conditions
as they exist and can be evaluated on, and on the information made available to
us as of, the date hereof. We have assumed that in the course of obtaining the
necessary regulatory or other consents or approvals (contractual or otherwise)
for the Merger, no restrictions, including any divestiture requirements or
amendments or modifications, will be imposed that will have a material adverse
effect on the contemplated benefits of the Merger.
 
     In connection with the preparation of this opinion, we have not been
authorized by the Company or the Board of Directors to solicit, nor have we
solicited, third-party indications of interest for the acquisition of all or any
part of the Company. In addition, we have not participated in any discussions or
negotiations among representatives of the Company and the Acquiror, including
the Acquiror's financial and legal advisors.
 
     We have, in the past, provided financial advisory and financing services to
the Company, including having acted as lead underwriter in connection with its
initial public offering on May 9, 1996 and with its offering of 6% Convertible
Trust Originated Preferred Securities on November 1, 1996, and to the Acquiror,
including having acted as lead underwriter in connection with its offering of
Class A Common Stock on September 19, 1995, and may continue to do so and have
received, and may receive, fees for the rendering of such services. In addition,
in the ordinary course of our business, we may actively trade the Company Shares
and other securities of the Company, as well as the Acquiror Shares for our own
account and for the accounts of customers and, accordingly, may at any time hold
a long or short position in such securities. In particular, as of September 24,
1997, we held, for our own account, a short position of 800 Acquiror Shares, a
short position of 76,300 Company Shares and a long position of 62,600 shares of
the Company's 6% Convertible Trust Originated Preferred Securities.
 
     This opinion is for the use and benefit of the Board of Directors of the
Company. Our opinion does not address the merits of the underlying decision by
the Company to engage in the Merger and does not constitute a recommendation to
any stockholder as to how such stockholder should vote on the proposed Merger.

     We are not expressing any opinion herein as to the prices at which the
Acquiror Shares will trade following the announcement or consummation of the
Merger.
 
     On the basis of and subject to the foregoing, we are of the opinion that,
as of the date hereof, the Exchange Ratio in the Merger is fair from a financial
point of view to the holders of the Company Shares (other than the Acquiror and
its affiliates and New Rio and its affiliates).
 
                             Very truly yours,
