Nancy Sinoway Tailoring & 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

“Nancy is a Rock Star in the world of Fine tailoring. Love her!!!”

Joshua Gropper
Managing Partner, Gropper Law Group

“From simple tailoring, to repairing denim to creating the most gorgeous original designs (visit her studio in Port and you’ll see) – Nancy and her team of artisans never disappoint. She’s been my “go to” seamstress for years!”

Randi Yerman

“Nancy took my wedding dress and reworked it to create a 1st communion dress for my daughter. It made me cry it was so beautiful. Now she’s making a dress for my oldest for Pride Prom!
If you don’t go to her…you are foolish. Her attention to detail is impeccable.”

Keri D.

I had a little over a week left before flying out to a wedding and needed a fully-beaded gown hemmed. I didn’t want to entrust it with just any tailor and someone from town recommended Nancy. I didn’t know I needed an appointment but she was nice enough to accept the job and finished my dress days before the event! Total lifesaver!

“Nancy is a pro and a perfectionist–two traits every tailor should have. She’s also a delightful person. She really knows her craft and how to make clothes fit properly. I learned the hard way that I couldn’t trust any of the local cleaners to do alterations.”

Andrea C.

“Nancy Sinoway took my wedding dress and made me love it even more. She paid attention to every little detail and it just turned out beautifully.-even the ribbon used for my bustle is lovely! I had to go back several times for fittings and I looked forward to seeing Nancy, Smitty and the rest of the caring seamstresses. Who would have thought that this would have been such a fun process? Bottom line is: excellent work done by even better people. I cannot recommend her services enough.”

From Dressmaker to Mask Maker

When my business was shut down due to the coronavirus, I knew I couldn't just sit by and not do something. I wanted to keep my staff employed - they rely on this income to feed their families - and I wanted to help my community. And so we are producing 100% cotton...
