I bought this to swim in because I have a long waist and one piece swimsuits are uncomfortable. I orginally bought the medium size but it was very loose and didn''t provide much support in the water. Thinking that if I went a size down I would get a tighter fit and more support, I ordered the small. I was wrong. There just is no support like the material they use in their one piece suits. So now I have two suits that are useless to me. Truly a waste of my money!
