I ordered this swimsuit with matching coverup dress. The swimsuit fits pretty good for S, M, L sizing convention versus 2, 4, 6, 8, 10 etc. I think there would be more accuracy in sizing if you are between a medium and small for example. I kept it and still like it. The quality is good. Only other improvement I could think of would be if the fabric had a bit more support to help hide the bulges.
Love how this fits and covers.
