I bought this leotard for my beginning ballet class and so far have been very pleased with my purchase. I didn't have any issues with sizing, I got a size small and I'm 5'3", 115 lbs. It does feel tight when you're putting it on, but once you have it all the way on it's a good level of tightness- it holds everything in but you can still move around comfortably. I also really like the shelf bra feature, I wear a 32C and don't need to wear anything under this leotard!
