First off. I was so impressed with how well made it was. I'm 5'3,148lbs with 36D cup size. I purchased the Medium. It fits snug but that's how I like it but breathable if that makes sense. I was so shocked at how well it supported my boobs with no bra. I didn't buy with the intent to workout in BUT now i kinda want to. I tested it out. YES. I shook my tay-tas. I jumped up and down. I got really weird. Me to me: "whats our limit man? We're gonna find out sis." I have the type of boobs that jiggle just from walking with a basic bra. Lemme tell you. They didn't move in this. I also did a squat test. I was fine there. "It has lil pads on the inside too. I was feelin myself. I believe I bought the beige or tan one because it pops against my brown skin. I Don't have a huge but, BUT it sure makes it look good.
