I wear a 32B bra and ordered a medium in this top. It did not cover the girls well at all. First of all, there's no padding or support in this top so they wanted to fall right out the bottom. I could see myself easily flashing everyone with a simple tug on the straps to adjust myself after getting out of water. There was also nothing built into the suit to position the girls in a flattering way. It was either you have a perfect chest or you don't with this. I think it may work for someone with a smaller chest but even then I don't know that most women would be comfortable in this top as I'd seriously question if your boobs will actually stay covered in it regardless of size.
