FAQs

Does this have an underwire?


No. The Rounded Square Neck One Piece is wire-free with a built-in shelf bra and removable moulded cups for support and shape - no underwire needed.

What bust sizes does it suit?
Designed for A-F cup busts. The shelf bra and removable moulded cups provide support and coverage across a wider bust range than most one pieces.

Does it run true to size?
Yes. Choose your usual size based on our size guide. If you're between sizes, size up.

Can I wear it as a bodysuit?
Yes. The Rounded Square Neck One Piece is designed to work as both swimwear and a bodysuit - pair it with jeans, linen pants or a skirt and it looks intentional, not like you forgot to change.

How does the compression feel?
Supportive, not restrictive. The 360° power mesh through the midsection gives you a smooth, sculpted feel that's comfortable enough to wear all day - firm but never tight or uncomfortable.

Is it good for tummy control?
Yes. The 360° power mesh compression smooths and sculpts through the midsection with a no-dig design - no rolling down, no digging in.

What's the coverage like?
High-cut leg with medium bum coverage. The square neckline sits modern and structured - confident without being revealing.

What's the fabric like?
Matte Luxe Jacquard Rib - thick, textured and fully lined with a 4/5 chlorine resistance rating. Holds its shape in and out of the water.

Are colours true to photos?
Yes. Colours are photographed in natural light, though slight variation can occur depending on screen settings.
