Item 2.   Identity and Background.

     The Statement is being filed on behalf of Ludwig G. Kuttner, a United
States Citizen ("Mr. Kuttner"), Hampshire Investments, Limited, a Delaware
corporation ("HIL"), and K Holdings, LLC, a Delaware limited liability company
("K Holdings," and together with Mr. Kuttner and HIL, the "Reporting Persons").
Of the 300,000 shares of Common Stock deemed to be beneficially held by Mr.
Kuttner, 250,000 are held directly by K Holdings and 50,000 are held directly by

outstanding interests in HIL. Mr. Kuttner, K Holdings and HIL have acted in
concert together from time to time with respect to the voting of the shares of
Common Stock beneficially held by each of them and may act together with respect
to the voting of such shares in the future; consequently, the Reporting Persons
may be deemed to constitute a "group" within the meaning of Section 13(d)(3) of
the Securities Exchange Act of 1934, as amended.

     Mr. Kuttner is the Chairman and Chief Executive Officer of Hampshire Group,
Limited, a Delaware corporation ("HGL"), which has principal executive offices
located at 215 Commerce Boulevard, Anderson, SC 29625. HGL is an apparel company

     None of the Reporting Persons has, during the last five years, been

     None of the Reporting Persons has, during the last five years, been a party

mandating activities subject to, federal or state securities laws or finding any
violation with respect to such laws.




Item 3.   Source and Amount of Funds or Other Consideration.

     The total amount of funds used by the Reporting Persons to purchase the
shares of Common Stock described herein was $2,100,000 and was furnished from
the personal funds of Mr. Kuttner.

Item 4.   Purpose of Transaction.

     The purchase by the Reporting Persons of beneficial ownership of the shares
of Common Stock as described herein was effected because of the Reporting
Persons' belief that the Issuer represents an attractive investment based on the
Issuer's business prospects and strategy. Depending on prevailing market,
economic and other conditions, the Reporting Persons may from time to time
acquire additional securities of the Issuer, engage in discussions with the
Issuer concerning further acquisitions of securities of the Issuer or otherwise
invest in the Issuer or one or more of its subsidiaries. The Reporting Persons
intend to review their investment in the Issuer on a continuing basis and,
depending upon the price and availability of the Issuer's securities, subsequent
developments concerning the Issuer, the Issuer's business and prospects, other
investment and business opportunities available to the Reporting Persons,
general stock market and economic conditions, tax considerations and other
factors considered relevant, may decide at any time to increase or decrease the
size of their investment in the Issuer or to sell any or all of the securities
of the Issuer that they hold.

     The Reporting Persons may in the future seek to engage in discussions with
management of the Issuer concerning the possibility of a representative of the
Reporting Persons becoming a member of the board of directors of the Issuer
and/or concerning potential investments by the Reporting Persons in securities
of the Issuer and/or its subsidiaries. Such discussions may relate to one or
more the transactions specified in clauses (a) through (j) of Item 4 of Schedule
13D.

     Other than as set forth above, none of the Reporting Persons has any
present plans or proposals which relate to or would result in any transaction,
change or event specified in clauses (a) through (j) of Item 4 of Schedule 13D.
