There are plenty of good reasons to buy a one-piece bathing suit. Maybe you like a little more coverage from your swimwear. Maybe you prefer a vintage-inspired look. Maybe you want something you can wear off the beach, with your regular clothes. Maybe you’re still holding on to childhood ambitions of becoming a lifeguard and want to have the uniform handy. If you identify with any of those—or maybe just want to upgrade your swimsuit before summer begins—then you should buy a one-piece.
Unlike bikinis, one-piece bathing suits can easily be incorporated with the rest of your wardrobe, doubling as a bodysuit to be styled with your favorite pair of jeans or with a skirt. There’s also something about them that feels timeless and chic. And you can just as easily find one that’s super simple as one that incorporates the season’s biggest trends. Need proof?
