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!"

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.
