Find your summer confidence this season and the next with Sea Level's collection of underwire bikini tops and swimwear with thoughtful, structured designs that provide extra lift, shape and support for larger busts or women wanting a little more structure to their bikini.

Designed in flattering shapes, with sculpting support, our underwire bikini top and swimwear range provides lift and structure to all bust sizes without rubbing or causing unnecessary tugging beneath the bust. Our underwire bikinis have been crafted to offer the support you need from diving beneath the waves to resort wear dressing without compromising on your comfort.

Crafted from stretch-approved fabrics, our underwire bikini tops will also move with you, so you don't need to feel restricted while spending time in the water, whether you're surfing, paddleboarding, or simply diving beneath the waves.

From underwire bikinis in bold prints to timeless staples to be loved this year and the next, all our underwire swimwear styles are lovingly designed with premium recycled nylon, so you can not only look your best but feel good about your environmental impact as well.

Whether you're after a more structured bikini top design or require additional support without compromising on your beach style, our underwire bikini top range has you covered. Specifically designed to support larger bust sizes, our underwire bikini tops feature details like hidden underwire as well as additional features like thick supportive straps or additional boning that helps to provide shape, structure and support to busts A-DD.

Our underwire bikini top collection offers a secure fit without pinching, shifting or digging into the skin, providing a comfortable fit that enhances your natural curves. If you're looking for a new underwire bikini set to complete your beach wardrobe, our range includes a number of styles and colors from vibrant prints to underwire bikini tops in classic and timeless hues that pair effortlessly with the rest of your resort wear wardrobe.

Premium Underwire Bikini Fabrics

All of our swimwear styles, including our underwire bikini tops, are crafted with the environment in mind! We design our underwire bikinis in eco-conscious regenerated nylon yarns and power mesh lining, ensuring that each underwire bikini is ultra-soft and equally sustainable.

Our underwire mesh and recycled fabrics also provide a more breathable and durable option than your other bikini tops with smooth-to-the-touch finishes that also stretch with you, so you can wear your underwire bikini top for years to come.

Find Your Perfect Fit

At Sea Level, our underwire bikini tops are crafted with all bodies in mind! Our bikini styles feature details that provide coverage and comfort from A-DD cup sizes and include thoughtful details like soft, removable cups, adjustable straps or underwire bikini tops with butterfly back clips so everyone can find an underwire bikini that suits their style or fit.
Whether you are after a bikini top that provides additional coverage and support for smaller busts, or you have a larger bust, our underwire bikini top range has been designed to provide support for sizes DD/E, so you can find confidence in the water and out of it.

Styling Your Underwire Bikini

Our underwire bikini tops prioritize your comfort and your style with a range of fashionable colorways and prints, so you can style your swimwear for any summer occasion. Complete your beach look by pairing your favorite Sea Level underwire bikini top with a matching pair of swimwear bottoms or mix and match an underwire bikini with a different pair of bottoms, like a cheeky cut or high-waisted bottoms, to add your own flair to your summer-ready look.

If you're after additional coverage or want to take your swimwear look from the beach to the beach club or a sunset dinner, layer your underwire bikini and swimwear bottoms beneath a lightweight and breathable kaftan or sundress to easily transition from day to night.
