Underwire Bikinis

Underwire support boosts our confidence - as well as our cleavage! Feel ready for sunny days with Boux’s range of underwired bikini sets: enhance your silhouette with a push-up bikini style, or choose a beautiful balconette style and dive into summer without risking any slips. Choose from our extensive range of bikini bottoms; from a high waist to a side-tie brief, dress yourself in the sexiest styles. We’ve got plenty of one-piece swimsuits, too, if that’s more your vibe.
