It seems the only way to get this one is by cup. So I got a cup 34C and the bra fit is nice. The reason why I'm giving it only 3 stars is that I was hoping this would actually help me to hide the little belly I have, helping me look with a little smaller waist. It did only a little bit. This is the third product of this kind I've gotten and it is by far, the largest! I am usually size 4 petite, although  I think I'm getting to size 2 these days (recently size 4 is a little too loose for me). I would recommend, but only if you are a size 5 or so. If you are a 4 or smaller this is not gonna help you shape waist/belly that much. I'm keeping it, because I like it anyways...  it looks sexy :)  but it kind of defeats its purpose...  to help with shape!
