Find Your One-Piece

Leakproof swim works in layers

The 3-layer liner absorbs and locks in leaks, whether you're in or out of the water. When washed with detergent, blood releases through the top layer for a fresh, clean suit.

Top Layer

A silky-smooth top layer that feels just like a regular swimsuit.

    Beautiful Color, Modesty Cut, No nipple pad

    I like this swimsuit in cherry, it's high neck style is great modest cut and it would have been perfect if it had a little nipple padding. The clasp is a bit hard to put on yourself, gotta get used to it.

    Cute but not supportive

    Love the colour and silhouette but unfortunately this has absolutely no support, even the under bust elastic is sewn so that it provides no tension under the bust.

    Outstanding

    I went wild swimming in Scotland in this suit and it was fantastic. It did not ride up and helped keep the girls in place. Highly recommend.

    Couldn’t return

    I was disappointed that I was within the window of return time with all of the policies met. The suit did not fit. I sent an email questioning why I couldn’t return the item and didn’t have the courtesy of a response.
