At Splash Swimwear, we believe every body deserves to feel confident, supported and stylish in swimwear. Our plus size one piece swimwear collection is thoughtfully curated to flatter curvy figures, offering beautiful designs in extended sizes that celebrate shape rather than hide it.

From classic silhouettes to modern, fashion-forward styles, our range includes everything from sleeved, ruffled and strapless one pieces to flouncy, retro-inspired designs and plus size swim dresses for those who love extra coverage with a feminine touch.

Flattering Plus Size One Piece Swimwear Australia

Our plus size one piece swimwear Australia collection is designed with comfort and confidence in mind. You’ll find swimsuits featuring:

  • Supportive bust construction and built-in shaping

  • Clever design details such as ruching and paneling

  • Styles that smooth and contour the body

  • Secure fits that feel comfortable all day

Whether you prefer a low-back one piece, a full-length sleeve style for extra coverage, or a classic supportive silhouette, Splash Swimwear offers options to suit a wide range of body shapes and swim needs.

Strapless, Supportive & Active Plus Size Styles

For women who love going strapless, our collection includes plus size bandeau one piece swimwear designed to stay in place while offering flattering support. Adjustable features and flexible shaping help these styles work beautifully for curvier bodies.

If you’re more active in the water, we also stock chlorine-resistant plus size one pieces, ideal for lap swimming, aqua fitness or regular pool use. These swimsuits are made to retain their shape and colour while providing lasting comfort and support.

Complete Your Look with Plus Size Cover Ups

To complement your swimwear, Splash Swimwear also offers a range of plus size cover ups, including wraps, sarongs and kaftans. Designed to fit and flatter, these pieces make it easy to transition from beach to poolside with confidence and style.
