I read other reviews mentioning that it's a hit or miss with the sizes.. I'm a 36C normally for a bra so I went down a cup and up a size to 38B.The cup seems to be good but the size should be 36 since it's slightly loose especially around my belly. It hits about near my belly button. To have more push and security that it won't fall down, I'm going to exchange it for a 36B
