  • 6/6/2017 very satisfied

    5 Review Stars By Kay

    I swim everyday. I usually change my swimsuit every 2 or 3 months but this one feels like new everyday. I've been wearing this for 2 months now. But only thing I was disappointed is sizing. It is too big. I usually wear 34 but this one 32, you should buy one size down. Color is very nice, I bought red and blue. I am wearing red right now and I got lots of compliments. I am 125 lbs, 5'4"

  • 2/12/2017 Baggy leg openings

    3 Review Stars By Kathy

    Sizing was right in the body of the suit but leg openings are baggy, causing the suit to ride up.  I will probably not get much use out of this because of the fit.  I swim daily so want a little more coverage than this suit provides.
