about us

Nancy Sinoway Tailoring and Alterations Studio has been on Earth since 1975.

Our “creative” experience includes, sophisticated tailoring and alterations, custom women’s dressmaking, ‘one-of-a kind’ Bat Mitzvah and Sweet 16 dress design, re-cycling of old Wedding Gowns into new, and ‘upcycling’ fur coats old or new to be current of today.

Over the years we have experienced lovely journeys with families, from Christening, Communion, Bat Mitzvah, Sweet Sixteen, Wedding and now dresses for their Children. Our client base has come full circle….and it is wonderful.

Our studio is a full service design house….and we can do just about anything creatively. There is no other place around like Nancy Sinoway Design! All of our services are on a one to one basis….. and handled with the tender loving care that our loyal clients deserve. All of our work is done on the premises, in our design studio in Port Washington, New York.

Nancy Sinoway Tailoring and Alterations works by appointment only. All projects are delivered in a prompt, professional and timely matter.
