Swimwear that fits like your favourite bra

We know how to support you. We've been doing it for decades with our bras, and we bring that same expertise to our ladies swimwear. Underwired bikini tops with proper cup sizing. Adjustable straps that actually adjust. Bands that grip without riding up when a wave catches you off guard. This isn't swimwear designed on a flat sketch. It's swimwear shaped by everything we know about how real bodies move.

Our one piece swimsuit range is built for women who want coverage and style in equal measure. Ruched panels smooth the midsection. Plunge necklines add a touch of drama. And our chlorine-resistant fabrics hold their shape and colour swim after swim, so that holiday investment keeps paying off long after you're home. If you love the pool as much as the beach, these are the swimsuits that'll keep up with you.

Bikinis deserve the same care as your best lingerie. Our bikini collection lets you mix and match tops and bottoms to suit your shape. Fuller bust? Choose an underwired top with wider straps. Prefer minimal lines? Our bandeau and triangle styles give you a sun-ready look with less coverage. High-waist bottoms, classic briefs, tie-side options. You build the set that works for you.

Triumph swimwear comes in prints, plains and everything in between. Bold tropical patterns for the beach bar. Classic navy and black for the morning swim. Whatever your style, the construction underneath stays the same: quality fabric, thoughtful design and a fit that gives you that feeling of everything being exactly where it should be.

Planning a holiday? Browse our swimwear alongside our strapless bras for those off-shoulder evening looks, or check our sale section for last-season swimwear at reduced prices. Need help finding your bikini top size? Our bra size calculator works for swimwear too. And don't forget to visit our magazine for packing tips and holiday style inspiration.
