I ordered a Large. The cups were very small (B cup size) and the strings are not fully adjustable. It's one continuous string so when you try to tighten up the shoulder straps, it cinches up the cups and makes them even smaller!The bottoms were weird too. They were a true Large size. The front and back fabric pieces are slideable/adjustable on the strings. This could be convenient for sunbathing and tan lines, however, the fabric pieces move around a lot just while you are walking. So, wear at your own risk!Was scared that I wouldnt like it, but when it came in and I put it on. I fell in love you have to get one. pictures dont do it any justice I promise you will not be disapointed
