25 Best One-Piece Swimsuits to Wear in 2023
One-piece bathing suits—whether a bandeau, a one-shoulder, or a long-sleeve style—can easily be incorporated with the rest of your wardrobe, doubling as a bodysuit to wear with your favorite pair of shorts or a cute beach skirt. Unlike some high-waist bikinis, which can lean too cheeky, there's something undeniably timeless and chic about a one-piece. And the versatile fit works for just about anyone, whether you're in need of a swimsuit for small boobs, a supportive bathing suit for larger busts, a plus-size swimsuit, or you're looking for none of the above but you'd love a bathing suit with tummy control and some extra coverage. For further proof, we found the 27 best one-piece swimsuits for 2023 from the best swimsuit brands that cover every style preference and budget (yes, including swimsuits under $100)—beach cover-ups sold separately.
