Shopping for plus size underwire swimsuits shouldn't feel like a compromise between style and function. The right swimsuit gives you the bust support you need while looking like something you actually chose, not something you settled for. At Lands' End, we design our plus size swimwear with underwire options with the same attention to detail and pattern variety we put into every piece of our women's swimwear. Internal wiring is sewn into structured cups that hold their shape in and out of the water. We use soft ining along the wire channels so nothing digs or pinches during a full day of wear. The result is a swimsuit that provides all the support of your favorite everyday bra paired with Lands' End styling.
Our underwire swimsuits use encased wiring with molded or seamed cups to give you lift and separation that stays put. We design the cups to contain and shape rather than compress, so you get a natural silhouette rather than a flattened look. Adjustable straps let you fine-tune the fit through the shoulders, and power mesh lining through the midsection provides gentle smoothing without restriction.

Support is the foundation, but style is what makes you want to wear the suit. Our plus size swimsuits with underwire come in everything from bold prints to solid colorways, so you can find something that reflects your style. V-necklines elongate the torso and create a flattering frame for a larger bust. Scoop-neck and sweetheart cuts offer a little more coverage up top while still showing off the neckline. Pair with a women's plus size coverup for a full water-ready look. Ruching along the midsection adds texture and provides a visually slimming effect without extra compression. We build every suit to look intentional on your body, because good design and good support belong together.
If you prefer full-coverage streamlined styling, many of our women's plus size one piece swimsuits pair underwire support with flattering silhouettes that move with you in the water. One-pieces with tummy control panels and built-in bra structures give you a smooth look from top to bottom. For those who want more flexibility, our women's plus size tankini tops offer similar support with the convenience of a two-piece. Mix and match your tankini top with your preferred bottom for a combination that fits your body and your plans for the day.
We build our plus size underwire swimsuits with chlorine-resistant fabrics that retain their color and stretch. The underwire casing uses reinforced stitching at every stress point so the support structure stays intact through hundreds of wears. When you invest in a Lands' End swimsuit, you're getting a piece that performs just as well after months of wear as it did on day one.
Absolutely. Our underwire swimsuits use encased wiring and secure cup construction that holds up during active movement in the water. The power mesh lining keeps everything in place so the suit doesn't shift mid-stroke. For the most active use, look for a style with wider straps and a higher neckline for extra security.
Rinse your swimsuit in cool, fresh water after every wear; saltwater and chlorine are the two biggest culprits for wire degradation. Lay the suit flat to dry rather than hanging it by the straps, which can stretch the cups and pull on the wire casing. Avoid wringing the suit out, as twisting can permanently bend the wire.
Soft-cup suits use fabric construction and elastic for shaping, which works well for lower-impact activities and smaller cup sizes. Underwire provides rigid structural support that lifts and separates, making it the stronger choice for D cups and above, where fabric alone may not hold the bust in place. If you've ever felt unsupported in a wireless swimsuit, underwire support will likely solve that problem immediately.
You deserve a swimsuit that keeps up with you, in the water and out of it. Plus size underwire swimsuits from Lands' End combine real bra-level support with styles you'll feel confident wearing all day. Browse the full collection and find your fit today.
