I returned a different suit and exchanged for this one instead. I am so glad that I did! This suit is beautiful and fits me perfectly. On the previous one-piece suit that I purchased, I had bought a medium because those are the sizes of the two-pieces and sports bras/shorts that fit me best. But on the other one-piece, I felt like I could have easily sized down. So on this exchange, I took a chance and purchased a size small. I am very glad that I did that, because the small fits me great. This suit isn't too revealing, but shows just enough cheeks to make me feel strong and confident. I love that the back is adjustable, and I feel like even if I gain or lose a few more pounds it would still fit me. For reference with the sizing, I bought a small and my measurements are 36/29/38, about 138 pounds and 5'4" tall.
