How about the Museum at the Fashion Institute of Technology in New York,
New York?  Address is: Seventh Avenue at 27th Street, NY, NY  10001-5992.
Dorothy Globus is the Curator, and while she's exceedingly nice, I know
she's also very busy.  Perhaps a member of her staff could help you?
(212) 760-7970.

And have you tried calling the Metropolitan Museum of Art costume
department as well?  I understand that you may not be able to travel to
these collections, but perhaps members of the staff can direct you to a
more specifically electronic resource.
