Designed in Australia for real women, our one piece swimsuits are made to make you feel incredible in and out of the water. Every style features built-in support panels, premium quick-dry fabric and thoughtful details that enhance your shape — because looking good at the beach shouldn't require a compromise.

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.

Size inclusive one piece swimwear

At Active Truth, we believe every woman deserves a one piece swimsuit that fits properly. Our entire range is available in sizes 8 to 26, with each size independently graded for the right proportions of coverage, support and comfort. No generic scaling — just a swimsuit that works for your body.
