Listen to the other reviews and SIZE TF UP! I’m 5’4”, 135 lbs, chest size 34C. I usually wear a S in swimsuits, XS/S in bodysuits. Based on reviews I figured an M would be perfect for me but it wasn’t available so I took a chance and ordered an L and I’m so glad I did. I was nervous bc I’ve never worn a L in a swimsuit ever, and I didn’t want this to be loose at all. It’s not. It fits perfectly, if anything maybe even a little tight. This suit absolutely runs small asf so be aware of that. That’See full review
