I wish the material on these was a bit thicker, but at least they fit. I will try them at the pool tomorrow and update. Okay I tried them today and really liked them. I wasn't swimming I was only doing aqua therapy because I have a serious back injury and will have surgery in a couple of months.  I ordered two sizes larger than I thought I needed because the last pair I ordered from a different vendor were so small. They fit fine even at two sizes up so if you want them to be high wasted i would order over size. They looked a lot better with my tankini top than alone.
