I looking for the web sites of tailors/suitmakers to whom I can send a
favorite wool women's suit  (jacket and sheath dress) for duplication
in a selection of wools.  I have heard that there are businesses in
Thailand (?) who
offer this service. But I'd prefer an american business.

This Hong Kong tailor might be worth contacting:

"Our Master cutters can even copy a garment that you like or can make
you a garment from a picture you have."
