Does a swimsuit offer the same support as a bra?

Our supportive underwire swimsuits are carefully crafted to offer the same support as our much-loved bras. Often, you’ll find swimwear using dress sizes, which can’t offer you the best fit possible. With Fantasie’s cup-sized swimwear you can ensure a look and feel of complete comfort and support suitable for all day wear. Complete your poolside look with our must-have beachwear styles.

What shape swimsuit is best for support?

All of our swimsuits offer an excellent level of support. Discover our Twist Front styles for a flattering sweetheart neckline with a gentle gather at the centre front, or explore our range our V-Neck Swimsuits for a plunging neckline and an enhanced cleavage.
