Designed by local watercolour artist Rachel Love

The Frankii Xover One Piece blends artistic expression with high-performance swimwear design. Featuring the exclusive Frankii print by Australian watercolour artist Rachel Love, this style is designed for swimmers who want comfort, coverage, and durability without sacrificing style.

Proudly designed and made in Australia, the Xover One Piece delivers a supportive, confidence-boosting fit — ideal for training, lap swimming, and long sessions in the water.

Why Choose the Frankii Xover One Piece?

The Xover One Piece is designed for swimmers who prefer fuller coverage and all-day comfort. With wide crossover straps, a supportive back design, and a fuller bottom, this style offers a secure and flattering fit across a wide range of body types.

Recently updated for improved performance, the neckline has been raised by 3cm to enhance bust coverage and water flow. Select sizes also include the option of a built-in shelf bra for added support.

Designed with Meaning. Created for Performance.

The Frankii print is a celebration of flowers, movement, and natural form. Created by Australian watercolour artist Rachel Love, the artwork uses deep blues and indigo washes, allowing pigment and water to blend organically into a soft yet expressive mixed-floral design.

This artwork translates beautifully onto performance swimwear - maintaining the integrity of the original piece while supporting serious athletic use.
