Underwire Bikini Structure

An underwire bikini top uses horseshoe-shaped underwire rings for support, keeping your bust lifted. The underwire provides structural support without excess padding, so you can achieve lift without the bulk. Our plus-size bikinis with underwire offer additional support with strong clasps, adjustable straps for a personalised fit, and high-quality materials for lasting comfort.

Why choose an underwire bikini top?

A bikini top with underwire offers superior support and lift, like a bra. A well fitting and supportive swim top will reduce back and shoulder pain by taking the weight of your bust. Soft, thick straps feel secure and won’t dig into your shoulders. The underwire bra style lifts the bust up and away from the midsection, for comfort and a flattering silhouette. Underwire bikini tops look sexy and fun, with a classic beach babe aesthetic.

Who Can Wear Underwire Bikini Tops?

Underwire bikini tops are ideal for women with larger busts as the underwire offers superior support without the need for padding. That’s not to say women with smaller busts can’t benefit from an underwire bikini top. If you love the look and feel of a more structured bikini that provides bust lift and separation, an underwire top is ideal. You also have the benefit of adjustable straps to achieve the perfect, secure fit.

Our Underwire Bikini Top Styles

While the support structure is the same, you can still find variation in underwire bikini styles. Our collection includes the classic contour bra underwire bikini top that can be shopped in individual cup sizes. This is great worn on its own or as a swim bra under other swimsuits, to provide extra support when necessary.
