Thank you Tammy The Dreamy Nights Design actually transforms my body into looking fitter than I am! I’m impressed, and my boyfriend even asked “Did you get a new pilates instructor?” The best part is I can put it on right on top of my bathing suit and go about my day!

Thank you, Tammy, for your amazing masks!

Once we set our wedding date for May 2021, on top of all the other wedding day details to decide on, we also had to figure out how we would incorporate masks into our big day. I am so thankful that our wedding planner encouraged us to go with custom masks (because pictures last forever!) and introduced us to Tammy.

Tammy was a pleasure to work with from our initial phone call to the drop-off of our custom masks for my groom and me, our bridesmaids, groomsmen, flower girl, ring bearers and our mothers. I was able to send her pictures of everyone’s wedding day attire and she matched the masks perfectly. The masks were comfortable, durable and looked and felt like quality.

Leggings by Tammy S. have changed my life. They are so flattering and comfortable so I feel beautiful all day long. I can go from shopping to dinner and still feel glamorous. Tammy S. is an unbelievable fashion designer. I’m so impressed with the prints, construction and style.

Tammy’s leggings are amazing. The design and material is superior and the fit is incredible. I can dress them up and dress them down. Can’t wait to buy more!


Tina R., New York NY

I absolutely love everything about the leggings by Tammy S.! I just bought my second pair immediately after receiving the first pair and trying them on. The fabric is absolutely the best I’ve ever felt on any legging. The fit is perfect, I never ever have to pull them up while working out and the waistband is extremely flattering! Best leggings I’ve ever worn by far!

I love my by Tammy S. snakeskin leggings! They fit true to size and the wide waistband is so comfortable. They are available in so many fun patterns and I love that I can wear them during the day and then dress them up to go out at night!


Melanie, Westchester NY

I love these leggings! Not only are they incredibly comfortable, but the versatility is outrageous! I could dress these down for the day, or up for the evening. Definitely my new go-to pieces!


Felicia, New York NY

I love them! The crotch fits well, it gives me more shape in the bump area. The stitching is well done and the spandex material has enough stretch to hold in place with a firm grip to show off my assets. The waist band secures your love handles if u have them.


Pam H, Hoboken NJ
