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.

Our underwire bikini top collection offers a secure fit without pinching, budging 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 beachside wardrobe, our range includes a number of styles and colours 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 to 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 everybody 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 prioritise your comfort and your style with a range of fashionable colourways and prints, so you can style your swimwear for any summer occasion.

Complete your beachside look by pairing your favourite 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 summer dress to easily transition from day to night.
