our bestselling swim bottoms are designed with a high leg cut that flatters — and a high-rise waist that flattens, smooths (ie. no muffin tops) and can be folded down to a low-rise waist, should that be your preference. cut in Econyl®, a 100% regenerated nylon yarn that’s buttery soft, spandex-strong and SPF 50. (did we mention machine washable and quick to dry, too?) pair with the one crop for a super chic one-piece swim look.
