Arriving October 2026.
Finally, real bra support in a one-piece that took us two years to perfect! Braveheart is built with underwire, not hope, for a lift and shape that we think is actually flattering. Two cup fits, D-DD and E-F, built specifically for a larger bust. Wide adjustable straps and an adjustable back strap keep everything secure without digging in. Compression through the tummy holds you in, without the squeeze. Feel held, lifted and secure.
- CUP FIT - choose from 2 cup fits: D-DD or E-F, for a bra-sized swimsuit fit
- UNDERWIRE SUPPORT - built-in underwire for secure lift without digging in, built for a larger bust
- NECKLINE - sweetheart neckline with thin foam cups, sewn in for shaping that holds
- ADJUSTABLE - wide adjustable straps plus an adjustable back strap, with a 6-channel slider at the back for underbust adjustment
- TUMMY CONTROL - Fearless NoDig Design power mesh compression, held not squeezed
- COVERAGE - mid-rise leg, medium-to-full bum coverage, fully lined
- FABRIC - ultra-matte recycled swim fabric with contrast binding, a different fabric to the main body so colours don't bleed in the wash
- DESIGN - open back with brushed gold hardware, easy on and off
- STYLING - doubles as a bodysuit beyond the beach
- SIZE RANGE - XS-3X (Australian sizes 8-20)
This one took over 50 samples and two years across two manufacturers to get right. Supportive and waist cinching, the high-support one-piece that's timeless and lets you feel completely secure at the beach, pool, or on holiday.

Why You Can Trust Our Sizing
We surveyed 15,000 women before designing a single item and we're still listening.
Every item is fitted and tested on two sizes - a 10/12 (C-Cup) and a 14/16 (E-Cup) - then trialled on real women in their 20s to their 60's. Because no two bodies are the same.
When our fabric ran small, we changed the sizing. Feedback beats data, every time.
Sizes XS-3X. Built for the body you actually have.
