21 Long-Sleeve Swimsuits Taking Over Summer 2023

When you think of the best long-sleeve swimsuits, your mind probably goes to a utilitarian rash guard devised to keep you safe from water sport scrapes—and give you an extra layer of protection from the sun (especially if it's made with a UPF fabric). And while those are definitely benefits, we’ve actually seen tons of innovation in this category.

Best Long-Sleeve Swimsuits 2023:

The best swimsuit brands are making cute surf-inspired one-piece swimsuits, trendy puff-sleeve silhouettes, and long-sleeve crop tops that pair perfectly with a high-waist bikini bottom, and two-piece versions that double as cover-ups–all of which you can rock even if you're more of a beach reader than kayaker.

Whether you prefer the athletic look or simply want additional SPF, these long-sleeve, editor-approved suits are beckoning us like the waves—and you can bet we’ll be adding one to our poolside repertoire.

Pro tip: If your long-sleeve bathing suit comes equipped with a built-in shelf bra or padding, you don’t have to wear anything underneath your swimwear. However, if you like extra support, layer it over a bikini top designed for a larger bust.
