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–DD

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.

We hold stock in local warehouses in the US, the UK and Australia, so your order is sent from the warehouse closest to you. US orders ship domestically within the US, Australian orders from within Australia, and UK and European orders from our UK warehouse.

You'll see the shipping options available for your address, with costs and delivery dates, at checkout.

US orders:

Order by 3 PM ET for same-day dispatch on Priority. Business days are Monday to Friday, excluding public holidays, and don't include the day your order is placed.

UK, European and Australian orders ship from our local warehouses — options, costs and delivery dates for your address are shown at checkout.

Every order is tracked, and we'll email your tracking details as soon as it's on its way.

We accept returns and exchanges on eligible items within 14 days of delivery. A $9.95 return shipping fee is deducted from refunds. Items must be unworn and unwashed with the hygiene liner and all tags intact, and your order number written clearly on your return label or package.

How a refund is issued depends on the discount: anything 20% to 29.99% off is refunded as store credit, and anything 30% off or more is exchange-only and can't be refunded. Exchanges are free except on items 30% off or more — see below.

Multi-buy discounts such as "2nd Swimsuit & Save" only apply while you keep the qualifying number of suits. If you return one suit from a multi-buy order, the suit you keep reverts to full price and the discount you no longer qualify for is deducted from your refund, whichever suit you send back. For example, two suits bought for $169.90 and $117.00 refund $117.00 less the $9.95 fee when either one comes back.

You can always exchange for a different colour, sale items included, as long as we have that colour in stock. Because our suits are one size and stretch with you, fit is rarely what people want to change — colour is, and that's an easy swap.

On items discounted 30% or more, an exchange carries the $9.95 return shipping fee to cover sending your original back to us — and we'll pay to ship your new colour out. Exchanges on everything else are free.

Refunds are what change with the discount:

• Less than 20% off — refund to your original payment method, or a free exchange.
• 20% to 29.99% off — refunded as store credit rather than to your card. Exchanges still free.
• 30% off or more — exchange only; these can't be refunded to your card or as store credit.

Sale stock is limited and we can't promise a colour will still be there at the end of the season, so tell us early if you'd like to swap. For everything else about shopping our sale, see our Sale FAQs.
