Runs REALLY SMALL
I'm a petit person 5'2 110lb I was debating between XS and S then decided to go with S after reading reviews. Arrived fast and well packaged (of course it's $200 swimsuit) but as soon as I slid my legs in I figured it way too small. I was able to wear it but I looked fat. It fits like a body shaper. Makes your belly and chest flatter. I'm not even sure if M would fit comfortably so I decided to return. Nice and thick material that seems to last long time.

Hi Petra,
Thank you for leaving a review. Absolutely LOVE hearing this. We agree the cut is very flattering.

Great fit and beautiful cut!
This one piece made me feel so great! I gained weight this pandemic but stayed true to a L size and fits great. There’s a lot of comments about the bust/torso but I think it’s the style and cut they’re going for, it’s low and I also thought it would be too short on the torso but for the cut/style it’s perfect and sexy! I love it!
