    Great fit, super function

    These swim shorts will keep you feeling snug, secure and stylish by the water. Even on your heaviest days, these will get you through to that post-pool shower time. Highly recommend.

    Very flattering!

    Love the cut of these. The legs stay put (no rolling up) and the waistline is flattering (no rolling down). Very comfortable overall. No leaks either, of course!

    Too snug

    I ordered a large as I’m a 13 but these were very small and snug and the fabric wasn’t stretchy enough
