FAQs

Our 'One Size Fits Most' method is suitable for a US 2–16 and UK/AU 6 - 16, depending on desired fit.

Our swimsuits work well over a baby bump, and post baby, as the material will stretch as your body adapts, and return to your desired shape afterwards.

It's likely! It's seriously flexible — in all directions.

Many people around 6ft tall wear our one-pieces and find the fit to be super comfortable.

Our suits don't include any built-in bust support, as this would limit their special ability to adapt to your changing body.

The super-flexible, seamless fabric adapts to fit your body and will lightly hug your shape in ways a typical swimsuit wouldn't — but this kind of support will come down to personal preference.

Our one-size swimsuit comfortably accommodates cup sizes A, B, C & D

While the suit offers excellent coverage, for extra peace of mind, if you have a large bust or darker areola, we recommend using silicone swimming nipple covers.

Our swimsuits are responsibly handmade in the UK.

The fabric is made of 95% Nylon and 5% Elastane.

With the right care, your swimsuit will be your go-to for seasons to come.

• Do not twist or wring, which will overstretch the (already stretchy) fibres of the suit
• Avoid contact with sunscreen, lotions, oils, or bleach — apply suncream once your suit is on and work around it
• Avoid spas or hot tubs
• Do not dry clean, tumble dry, or store when wet

If you do want to wash your suit: hand wash in cool, fresh water immediately after use (a small amount of diluted, mild detergent may be used), bunch into a ball and squeeze out excess water, then lie in the shade or hang to dry.
