ITEM 2.    ACQUISITION OR DISPOSITION OF ASSETS

(a)-(b)
           On December 15, 1999, The Warnaco Group, Inc., a Delaware
corporation ("Warnaco"), through A Acquisition Corp., a Delaware corporation
and a wholly owned subsidiary of Warnaco ("Purchaser"), accepted for purchase
19,526,560 shares of the common stock, par value $0.001 per share (the
"Shares"), of Authentic Fitness Corporation, a Delaware corporation (the
"Company"), that had been validly tendered and not withdrawn (including shares
tendered via guaranteed delivery) pursuant to Purchaser's offer for all of the
outstanding Shares at $20.80 per Share, net to the seller in cash, without
interest (the "Offer"). The Offer was made pursuant to an Agreement and Plan of
Merger (the "Merger Agreement"), dated as of November 15, 1999, by and among
Warnaco, Purchaser and the Company, which provided for, among other things, the
making of the Offer by Purchaser and, following the consummation of the Offer,
the merger of Purchaser with and into the Company (the "Merger"). The Shares
purchased pursuant to the Offer constituted approximately 96.95% of the Shares
then issued and outstanding. The aggregate purchase price for the Shares
purchased pursuant to the Offer was approximately $406 million.

           On December 16, 1999, the Merger provided for by the Merger
Agreement became effective. Pursuant to the Merger, Shares which were not
validly tendered pursuant to the Offer and accepted for purchase by Purchaser
(and whose holders had not sought appraisal of their Shares in accordance with
applicable provisions of Delaware law) were converted into the right to receive
$20.80 per Share, net to the seller in cash, upon delivery of appropriate
documentation to the Paying Agent for the Merger. As a result of the Merger,
Parent owns 100% of the outstanding Shares of the Company. The total amount of
funds required to consummate the Offer and the Merger, pay the fees and
expenses of the Offer and the Merger and refinance all the existing revolving
bank debt of the Company, was approximately $599 million (which amount includes
the $406 million required to pay for Shares purchased in the Offer, as set
forth in the preceding paragraph).

           The information  set forth herein has been previously  disclosed
by Warnaco in press releases dated November 15, 1999 and December 16, 1999,
and  in a  Tender  Offer  Statement  on  Schedule  14D-1,  filed  with  the
Securities  and Exchange  Commission  on November  17, 1999 (the  "Schedule
14D-1"),  and amended on December  16,  1999 (the  "Amendment  No. 1 to the
Schedule  14D-1").  Additional  information  concerning  the  Offer and the
Merger,  a brief  description  of the  Company,  the  nature  and amount of
consideration  paid for the Shares and the  source of funds  therefor,  the
principle  followed in  determining  the amount of the  consideration,  the
identity of the persons  from whom the Shares were  acquired and the nature
of any material relationship between such persons and Warnaco or any of its
affiliates,  any  director or officer of Warnaco or any  associate  of such
director  or  officer  and  the  nature  of the  Company's  business  and
Warnaco's  plans for the  Company  may be found in the  Schedule  14D-1 and
Amendment No. 1 to the Schedule 14D-1,  copies of which are attached hereto
