Reviews

Great thick cotton and quality

"Great thick cotton and quality is good, a little thin to wear with a tight fitting light colored top but really cozy and comfortable for day to day wear"

— Susan E. (5/5)

Every bra I have from

"Every bra I have from OB is S and fits me well and none of them is tight. I bought this bralette in S+ and the cups are a little to small and underband is more tight than usual. The overall fit is very supportive, soft nice material!"

— Nela G. (4/5)

I love that this bra

"I love that this bra is made by an ethical Company. It’s such a good fit. I’m a 34A, 53 and breast fed my children, so it’s very hard to find a bra that fits. This does! And it’s very comfortable."

— Sophie S. (5/5)

Love it. Finally a comfortable

"Love it. Finally a comfortable cotton bra. Tight fit so if you have a bigger chest i would size up."

— Sinja K. (5/5)

Overall satisfied

"I have it in 2 different colors! Otherwise I like this bra a lot but the cup size is a bit too small. If underband is good size then the cup is too small and if I take bigger size then underband is too big. . ."

Q&A

is the bra visible under tight shirts?
Hi Ada, that really depends on the color variant you choose and the type of tee you wear on top. Texture-wise, the bra is very soft and smooth, so it sits nicely under most shirts.
