text: I’m usually a medium. 5’5” about 145-150 pounds. This was a little small in the bust area. I’m a 36B. Would recommend getting the next size up if you have larger boobs, otherwise it’ll look like you have a uniboob. The back is totally open, so you can’t wear a bra anyways, and there is padding in there so it’s fine to go bra-less.
