Definitely size down if you think you are between sizes. I am a 32 D and don't like my tanks too tight so ordered the medium. I would order an xs if I could. This tank is very roomy. Even if I wear a tank underneath it just looks sloppy, so keep that in mind when choosing a size. The back has a criss cross detail and the hem is banded so hugs your hips and makes the rest of the tank blouse out a bit.
