  • 4/13/2021 a little big

    4 Review Stars By Love to swim

    I usually wear a medium top and this bra definitely drags in the middle.
    The bottom is nice because it has an adjustable strap you can tie.
    It's good workout piece but I'm definitely  calling it my "comfy" workout suit.
    too bad you can't mix and match.

  • 6/29/2010 Pretty Close to Perfect

    5 Review Stars By Traci

    I was skeptical about getting this suit as I have a hard time finding things that fit "off the rack". This suit fits pretty close to perfect. The bottoms are perfect. Not overly tight, just perfectly snug and have a draw string that cinches them comfortably in place. The top is a little big on me but it's not noticeable, I can just tell it's not real snug (the straps feel a bit too long). I just pull it down in the back to make up for the extra strap length. I use it for swimming on the Master's. For anybody who needs some specifics, I'm 5'5", 125# w/ measurements of 35-26-36. I ordered a medium. Hope that helps.

  • 4/4/2021 Perfect two-piece for lap swimming

    5 Review Stars By Jeannette

    I’ve been a fan of TYR for a long time. This suit provides adequate coverage, and it’s durable and flexible. It stands up to sun, salt and chlorine. It moves with you for a good workout. I basically purchase it in every color.

  • 8/16/2015 Fits well and I am happy with my purchase

    5 Review Stars By Novice Swimmer

    Adjustable string for the bottom to tighten before a swim. The sizing was a bit tough because according to the chart my chest is a large and my waist a small. The medium was a safe and good choice. A large top would have been too big and since the bottom is adjustable with the string I do not have any complaints about the size. I swim and have washed it often and the material is holding up very well

    5 Review Stars By Chemy

    I absolutely love this bikini swimsuit set and am over 60 years old.    I use it for my water aerobics class.  I have bought many different suits but this is simply the best.  It lasts, does not get saggy and does not fade.  I would recommend this swimsuit to anyone.

  • 4/11/2018 Lasts over a year with solid 2-3x/wk chlorine swimming

    5 Review Stars By NWMT IVY

    After over a year of use, I'm still using this 100% polyester (plastic) suit for 1-1.5 hour competition practices. The suit is only starting to turn white along one edge of the bottom and is slightly bigger than new, especially where the black is turning white. Only complaint is that I want more options for style and color.

  • 1/25/2021 Great fit!

    4 Review Stars By New go-to suit

    Fits well, looks flattering, and stays in place while lap swimming.  Top is comfortable and bottoms have a thicker waistband which serves to keep things from moving around.  Overall, a good purchase and a new go-to.

  • 7/27/2015 Great coverage in a 2-piece

    5 Review Stars By JenL

    My daughter wanted a 2-pc for summer swim team practices, and to wear under her wetsuit in open water racing.  She is a larger girl, and busty, so most of the 2-pc training suits looked too small in the top.  This one is great!  Fits well and looks good, and offers decent coverage and support.  She wants another one (in red) for lifeguarding!
