Supportive Underwire One Piece Swimwear Australia

Our underwire one piece swimwear Australia collection features a mix of timeless plains and statement prints to suit every taste. Designed with built-in bra support, these swimsuits are ideal for women with fuller busts who want reliable lift and structure.

Many styles are available in cup sizes from D to G, making it easier to find a swimsuit that fits properly and feels secure. Adjustable straps, quality fabrics and thoughtfully designed panels allow you to customise the fit for all-day comfort and confidence.

Full Piece Swimsuits with Underwire Support

A full piece swimsuit with underwire support is the perfect option for women seeking shaping, lift and definition through the bust. Underwire helps lift the bust away from the midsection, creating a more balanced and flattering silhouette that highlights the waist and curves.

By offering proper support and shaping, underwire one piece swimwear provides both comfort and confidence — allowing you to move freely while feeling secure and well supported. If you’re looking for a swimsuit that works with your body, an underwire one piece is a timeless and reliable choice.

Why Choose an Underwire One Piece?

Underwire one piece swimwear is ideal if you:

  • Need extra bust support and lift

  • Prefer a structured, secure fit

  • Want a flattering shape through the waist

  • Have struggled to find well-fitting swimwear in standard styles

Our supportive underwire designs are perfect for beach days, poolside lounging, holidays and everyday swimming.
