I own quite a few bodysuits and I think if I wasn't so tall it wouldn't have been a problem. I'm 5'8" with an athletic build and I ordered a medium. I should have ordered a large because length wise (up and down) was super snug and could have used an extra inch of fabric. Otherwise the fabric is comfy. The side's are very structured with not a lot of give in it eitherthis is really cute on but I am tall and normally wear a small so that is what I got and I for sure would have been more comfortable in a medium. I am 5'10 and 130 lbs usually wear a size 2Ordered this bodysuit for a lifeguard costume, it fit perfectly and is good quality for the price! I'm 5'2" 110 lbs and ordered the small.It Looked Perfect & Sexy on my Wife. Great BuyI loved it, but a little small.I love it so much
