Ok, sooooooooo! If you're slim thick, I mean, wide hips, big butt, tiny boobs(5'10", 34B-28-43, here). Good luck! I got a small. It's made well, BUT, It doesn't stretch much and it's hard as hell to get on. Once I did manage to get it on, it looked GREAT! The straps are adjustable, which is great for my long torso and it's pretty comfortable once I get over the pain in my fingers; the side boob is to die for. For the price, Prime shipping and what I'm using it for, it's perfect. Lol! *will post See full review
