For women with fuller busts, finding swimwear that fits, supports, and flatters has always been a challenge. Most luxury swim brands overlook curves or offer us a one size fits all DD+ option.
.
That's precisely why I founded Core Swim, to create fuller-bust swimwear without compromise: exclusive swimwear I was proud to wear, elegant swimwear that made me feel fabulous, supportive swimwear that empowered me to move with freedom and confidence.

Discover the freedom of swimwear that finally feels like it was made for you.
Perfect Fuller Bust Fit
At Core Swim, we embrace the complexity of fuller bust design, rather than shy away from it. Every piece is crafted with meticulous attention to fit, ensuring true fuller bust comfort, coverage, and support. Every curve and movement is considered. By drawing on lingerie-inspired design techniques and pairing them with carefully selected performance fabrics, our swimwear combines fit, function and design, delivering an anchored fit, effortless freedom of movement, and complete confidence - both in and out of the water.
Elevated performance, lasting comfort, and total bikini confidence.
Support is at our Core
Every fuller bust woman knows that true support is essential — for comfort, stability, lift, and confidence. That’s why every Core Swim piece features our exclusive Core Support System: an ultra-thin, invisible internal layer that lifts, sculpts, and stabilises, even when wet.
Enjoy all-day comfort — no strain, no slippage, no compromise. Just powerful, sculpted support that moves with you, giving you the confidence to swim, lounge, and enjoy every moment.
Sustainable Luxury
At the heart of Core Swim is our family-run Portuguese atelier, where every piece is cut, finished, and perfected with meticulous care. Each swimsuit is designed to last, not follow fleeting trends — combining timeless elegance, impeccable fit, and enduring quality.
We pair this artisanal expertise with Econyl® recycled fabrics, chosen for their soft touch, fast-drying performance, and superior shape retention. Resistant to chlorine, sun cream, and oils, and offering excellent UV protection, these fabrics ensure your swimwear remains beautiful and supportive season after season — all while reducing greenhouse gases and helping protect our oceans.

Customer Reviews
Bought my 4th bikini from Core Swim. Love the design, quality (support is fantastic and bikinis retain shape and colour through washing). Service is ace too - prompt delivery.
Love these high waisted bottoms. I feel covered and they’ve got a power lining in the tummy if you want some support
Fits perfectly!
It was definitely an investment but it actually makes me feel secure and feminine without showing too much
Gorgeous bikinis, perfect fit and quality fabric and manufacture. Delighted and so recommended. x
The shape is amazing and I feel completely secure. I always
buy bra sized bikinis but I can honestly say this is second to none I’ve tried
before.
