=============================================================================





                            INTRODUCTORY STATEMENT

          Jones Apparel Group, Inc. ("Jones" or the "registrant") hereby
amends its Registration Statement on Form S-4 (No. 333-75867) (the "Form S-4")
by filing this Post-Effective Amendment No. 1 on Form S-8 to Form S-4 (the
"Post-Effective Amendment" or the "Registration Statement") relating to the
sale of up to 902,000 shares of common stock, par value $0.01 per share, of
Jones ("Jones Common Stock") issuable in connection with options, shares or
rights to acquire shares, granted under the Second Amended and Restated Stock
Option Plan of Nine West Group Inc., the Nine West Group Inc. First Amended
and Restated 1994 Long-Term Performance Plan and the Nine West Group Inc. 1993
Directors' Stock Option Plan (collectively, the "Plans").

          On June 15, 1999, Jones and Nine West Group Inc., a Delaware
corporation ("Nine West"), consummated a merger (the "Merger") whereby Nine
West merged with and into a wholly owned subsidiary of Jones pursuant to an
Agreement and Plan of Merger (the "Merger Agreement") dated as of March 1,
1999. As a result of the Merger, Nine West became a wholly owned subsidiary of
Jones. Pursuant to the Merger and the other transactions contemplated by the
Merger Agreement, each share of Nine West common stock (other than shares
owned by Jones or Nine West or their subsidiaries), par value $0.01 per share
("Nine West Common Stock"), was converted into the right to receive 0.5011 of
a share of Jones Common Stock and $13.00 in cash.

          In addition, each outstanding option granted pursuant to the Plans
will no longer be settled in shares of Nine West Common Stock, but instead
will be settled on the same terms and conditions as were applicable
immediately prior to consummation of the Merger in that number of shares of
Jones Common Stock (rounded down to the nearest share) equal to the product of
(x) the number of shares of Nine West Common Stock which would have been
delivered pursuant to such stock-based award and (y) 0.5011. The exercise
price for each option to acquire a share of Jones Common Stock shall be equal
to (x) the original exercise price of such option less the cash portion of the
consideration paid in exchange for each share of Nine West Common Stock
($13.00) (y) multipled by one divided by the exchange ratio (1/0.5011). With
respect to each such option having the same exercise price, the number of any
fractional shares of Jones Common Stock shall be aggregated together to create
whole shares of Jones Common Stock, and the per share exercise price of each
option will be appropriately adjusted. Each outstanding option will otherwise
be exercisable upon the same terms and conditions as were applicable
immediately prior to the Merger.

          The Post-Effective Amendment relates to the offer and sale after the
Merger of common stock pursuant to the Plans.





                                    PART II

              INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

               31, 1998;

          (b)  Jones' Quarterly Report on Form 10-Q for the quarter ended

               1999; and

          (d)  Jones' Registration Statement on Form 8-A filed under Section
               12 of the Exchange Act on April 19, 1991, including any
               amendment or report filed with the Securities and Exchange
               Commission for the purpose of updating such description, in
               which there is described the terms, rights and provisions
               applicable to Jones' outstanding Common Stock.

          All documents subsequently filed by Jones pursuant to Section 13(a),

Statement and prior to the filing of a post-effective amendment to the Form
S-4 which indicates that all securities offered hereby have been sold or which
deregisters all securities then remaining unsold, shall be deemed to be
incorporated by reference into this Registration Statement and to be a part
hereof from the date of filing of such documents.

          Any statement contained in a document incorporated or deemed to be
incorporated by reference herein shall be deemed to be modified or superseded
for purposes of this Registration Statement to the extent that a statement
contained herein or in any subsequently filed document which also is deemed to
be incorporated by reference herein modifies or supersedes such statement. Any
such statement so modified or superseded shall not be deemed, except as so
modified or superseded, to constitute a part of this Registration Statement.

Item 4.        Description of Securities.

               Not applicable.

Item 5.        Interests of Named Experts and Counsel.

          The validity of the Jones common stock being offered hereby has been
passed upon by Ira M. Dansky, Esq., General Counsel of Jones. As of June 16,
1999, Mr. Dansky beneficially owned 8,226 shares of common stock, and options
to purchase 140,000 shares of Jones common stock.





Item 6.        Indemnification of Directors and Officers.

          The Pennsylvania Business Corporation Law of 1988 (the "Pennsylvania
Business Corporation Law") provides that a corporation may provide in its
by-laws that a director is not personally liable for monetary damages for any
action taken unless (1) the director has breached or failed to perform the
duties of his or her office and the breach or failure to perform constitutes
self-dealing, willful misconduct or recklessness, (2) the responsibility or
liability arises under any criminal statute or (3) the liability is for the
payment of taxes under Federal, State or local law.

          Section 8.1 of the Jones by-laws provides that a director shall not
be personally liable for monetary damages for any action taken or failed to be
taken, other than as expressly provided in the Pennsylvania Business Corporate
Law. Furthermore, Section 8.2 of the Jones by-laws provides that Jones shall
indemnify each officer and director to the full extent permitted by the
Pennsylvania Business Corporation Law, and shall pay and advance expenses for
any matters covered by such indemnification.

          Section 1741 of the Pennsylvania Business Corporation Law provides
that a corporation shall have the power to indemnify any person who was or is
a party or is threatened to be made a party to any threatened, pending or
completed action or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation), by
reason of the fact that he or she is or was a representative of the
corporation, or is or was serving at the request of the corporation as a
representative of another domestic or foreign corporation for profit or
not-for-profit, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him or her in connection with
the action or proceeding if he or she acted in good faith and in a manner he
or she reasonably believed to be in, or not opposed to, the best interests of
the corporation and, with respect to any criminal proceeding, had no
reasonable cause to believe his or her conduct was unlawful. The termination
of any action or proceeding by judgment, order, settlement or conviction or
upon a plea of nolo contendere or its equivalent shall not of itself create a
presumption that the person did not act in good faith and in a manner that he
or she reasonably believed to be in, or not opposed to, the best interests of
the corporation and, with respect to any criminal proceeding, had reasonable
cause to believe that his or her conduct was unlawful.

          Section 1742 of the Pennsylvania Business Corporation Law provides
that a corporation shall have the power to indemnify any person who was or is
a party, or is threatened to be made a party, to any threatened, pending or
completed action by or in the right of the corporation to procure a judgment
in its favor by reason of the fact that he or she is or was a representative
of the corporation or is or was serving at the request of the corporation as a
representative of another domestic or foreign corporation for profit or
not-for-profit, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees) actually and reasonably incurred by him
or her in connection with the defense or settlement of the action if he or she
acted in good faith and in a manner he or she reasonably believed to be in, or
not opposed to, the best interests of the corporation. Indemnification shall
not be made under Section 1742 in respect of any claim, issue or matter as to
which the person has been adjudged to be liable to the corporation unless and
only to the extent that the court of common pleas of the judicial





district embracing the county in which the registered office of the
corporation is located or the court in which the action was brought determines
upon application, that, despite the adjudication of liability but in view of
all the circumstances of the case, the person is fairly and reasonably
entitled to indemnity for the expenses that the court of common pleas or other
court deems proper.

          Jones has in effect insurance policies in the amount of $45 million
for general officers' and directors' liability insurance and $10 million for
fiduciary liability insurance covering all of Jones' directors and officers in
certain instances where by law they may not be indemnified by Jones.

Item 7.        Exemption from Registration Claimed.

               Not applicable.

Item 8.        Exhibits.

               See the Exhibit Index following the signature pages for a list
               of Exhibits to this Post-Effective Amendment.

Item 9.        Undertakings.

         (a)  The undersigned registrant hereby undertakes:

               (1) To file, during any period in which offers or sales are
being made, a post-effective amendment to this Registration Statement:

                    (i) To include any prospectus required by section 10(a)(3)
of the Securities Act of 1933;

                    (ii) To reflect in the prospectus any facts or events
arising after the effective date of the Registration Statement (or the most
recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in the
Registration Statement. Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar value of
securities offered would not exceed that which was registered) and any
deviation from the maximum aggregate offering price may be reflected in the
form of prospectus filed with the Commission pursuant to Rule 424(b) under the
Securities Act, if in the aggregate, the changes in volume and price represent
no more than a 20% change in the maximum aggregate offering price set forth in
the "Calculation of Registration Fee" table in the effective Registration
Statement; and

                    (iii) To include any material information with respect to
the plan of distribution not previously disclosed in the Registration
Statement or any material change to such information in the Registration
Statement or any material change to such information in this Registration
Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do
not apply if the Registration Statement is on Form S-8 or Form S-3, and the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the registrant pursuant to section 13





or section 15(d) of the Exchange Act that are incorporated by reference in the
Registration Statement.

               (2) That, for the purpose of determining any liability under
the Securities Act of 1933, each such post-effective amendment shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

               (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

          (b) The undersigned registrant hereby undertakes that, for purposes
of determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be
a new Registration Statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

          (c) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.





                                  SIGNATURES

          Pursuant to the requirements of the Securities Act of 1933, the
registrant certifies that it has reasonable grounds to believe that it meets
all the requirements for filing this Post-Effective Amendment No. 1 on Form
S-8 to the Form S-4 Registration Statement and has duly caused this
Registration Statement to be signed on its behalf by the undersigned,
thereunto duly authorized, in the City of New York, State of New York, on
June 16, 1999.
