FAQs About One Piece Swimwear

Are one piece swimsuits good for bigger busts?

Yes! Many of our styles offer built-in cup support or underwires. Brands like Sea Level and Jantzen are known for supportive swimwear that caters to fuller busts.

What’s the difference between a regular one piece and a surf suit?

Surf suits often feature zip-fronts, long sleeves and are designed for active water sports. They offer more sun protection and stay put during movement.

Do you have tummy control options?

Absolutely. We stock brands like Miracle Suit that offer shaping technology for a more defined silhouette and enhanced confidence poolside or beachside.

Can I try them on in-store?

Yes! Visit us at The Foundation in Neutral Bay or Rozelle, or Lin & Barrett in Bowral for expert help with fit and style. Our team will help you find the perfect one piece swimsuit for your shape and lifestyle.

What sizes do you carry?

We offer a wide range of inclusive sizes across our one piece swimwear. If you're unsure about fit, we recommend popping in-store for a personalised fitting session.
