  • 12/28/2020 Great suit.

    5 Review Stars By Norascats

    This suit fits well. It is poly so it should last a while. Ask me gain in two months. And the price was low.
    The only problem is the back piece was not lined. Since I back out of the pool onto a concrete deck I like a double behind.

  • 9/6/2020 A Good Workout Suit, But Beware of Ride-up

    4 Review Stars By elaine N.

    I'm in the pool four days a week, so I added this suit to my swim "wardrobe." So far it's retained its color well. Fit is looser than I'm used to, and leg holes aren't as tight as on my other suits; this one rides up so there's not as much rear coverage as I'd like. Straps are comfortable enough. Fabric is lightweight but high quality; front is fully lined. A decent suit for the price.

  • 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.
