One piece swimsuit styles

Core Support One Pieces: Our signature Coolum Core Support One Piece features internal support panels and a sculpting inner layer that enhances your natural shape. With adjustable straps, removable cups and a secure fit, this is the one piece swimsuit Australian women have given over 2,000 five-star reviews.

Effortless Elegance: The Sorrento One Piece offers a relaxed yet flattering silhouette with a scooped neckline and classic cut. Designed for women who want a timeless swimsuit they can dress up with a sarong or wear straight to the café.

V-Neck Styles: For a more open neckline with the same built-in support, our V-Neck Core Support One Piece delivers a lengthening silhouette with all the structure you need.

Premium fabrics built to last

Every one piece swimsuit in our range is crafted from high-quality performance fabric that is chlorine-resistant, quick-dry and rated UPF50+ for serious sun protection. Our fabrics are designed to hold their shape and colour wear after wear — no stretching, no fading, no compromises.
