Chlorine-Resistant Plus-Size One-Piece

Find the perfect fit for your summer fun with our chlorine-resistant plus-size one-piece swimsuits from Lands' End. Many of our swimsuits feature LYCRA Xtra Life spandex, which has a lifespan of up to 10 times longer than regular spandex. These suits don't just stand up to chlorine. They're also resistant to sweat, sunscreen, and the sun's rays. Our suits offer UPF 50 sun protection, which is the highest level available. The sun protection provided by these swimsuits is only for covered areas, so don't forget the sunscreen.

Our plus-size chlorine-resistant one-piece swimsuits come in a wide range of extended sizes so you can get the perfect fit for your needs. You can choose DD or DDD cup sizes to make sure the suit hugs all your curves just right. We offer several styles that will allow you to accentuate or minimize features as you see fit. You can enjoy elements like tummy control to smooth and shape around the midsection. You can camouflage thighs with everything from lower leg openings or a short-skirted overlay to a longer skirt that hits around the mid-thigh. 

If you're interested in additional coverage with these women's chlorine-resistant plus-size one-piece swimsuits, you can also select a women's rash guard or one of our swim cover-ups. These accessories are ideal for walking to and from the pool or beach or for taking a stroll along the boardwalk. Grab one of our canvas totes and beach bags to stash everything you need for your trip.

These one-piece chlorine-resistant plus-size swimsuits come in cuts that are cleverly designed to flatter any shape. You'll feel effortless elegance when you wear your perfect one-piece swimsuit.
