Whether you are heading to the beach or chilling poolside, get ready to make a splash with the season’s hottest swimwear looks. Shop our collection of Madewell women’s swimsuits for bikinis and one-pieces along with cover-up sarongs and caftans. Choose from premium brands like Seea, lemlem, NUSWIM, Belize, GALAMAAR and more. One of the most exciting trends in women’s swimwear is the use of eco fabrics like repurposed deadstock, regenerated fibers or organically grown natural fibers. All the swimwear styles in Madewell’s Second Wave collection are made of stretch fabrics recycled from pre-consumer waste. From bikinis to one-piece bathing suits with sexy cutouts to long-sleeve surf suits that protect your skin (you’ve got to see the rash guards from Seea), Madewell’s collection of women’s swimwear truly has something for everyone. For those who prefer a bit more coverage, one-piece women’s swimsuits are just as chic as bikinis (and have the added bonus of staying on while you splash in the water or chase after little humans). Show off your curves in one-piece swimsuits with plunging necklines, cutouts and low backs. Looking to bare your skin? There’s more to two-pieces than the ubiquitous string bikini. This season’s most popular women’s bikini designs include both cheeky, high-cut bikini bottoms or retro high-waisted bottoms. Bikini tops range from convertible halter tops to crop tees to protective long-sleeve swim tops. Monochromatic swimsuits for women are having a moment and you can choose from toned-down neutrals or tropical-inspired brights. Or switch things up in a retro floral or other bold print. And, when you’re chilling by the pool, don’t forget to add this season’s coolest women's swimsuit cover-ups like camp shirts, bikini-matching sarongs, breezy caftans, crochet dresses and airy pull-on shorts. Go from beach to bar in a cute romper with bow straps or pull on gauzy wide-leg pants and a cropped tee and platform sandals for a breezy look. For a quick cover, choose a crinkle cotton sarong wrap or slip on a maxi shirtdress in Lightestspun cotton and add a pair of chunky sandals. Label We Love alert: we’re big fans of Lemlem and its striped popover dresses in handwoven cotton. To get beach ready, shop online from wherever you are and have your order delivered to your door.
