I'm a 34B and the 34B fits perfectly! I was a little afraid of buying bras without trying them on first but this bra seems to be true to size. I like that the straps are nice and sturdy too and the bra is comfortable in general. The little bow on one side is cute too. I got black and taupe. It's a bit more expensive of a bra than I usually wear but I wanted to avoid the possible toxic side-effects of wearing synthetic bras...
Very comfortable fabric and the bra is well-made, but this kept riding up on me on one side. This is not for someone with more bust on the side than in the middle. But it might be great for you...
