If you have an account, log in to submit your return request. If you checked out as a guest, use our Guest Returns portal. Please review the return conditions before posting your item.

Items must be unworn, unwashed, unaltered and returned in their original condition. Swimwear must retain its protective hygiene strip and should only be tried on over underwear.

Return shipping costs are the customer’s responsibility unless an item is confirmed as faulty. We strongly recommend using a tracked service and retaining your proof of postage.

Items marked Final Sale cannot be returned for a refund or store credit unless they are confirmed as faulty.

Once your return reaches our warehouse, please allow 7–10 working days for inspection and processing. Your payment provider may then take an additional 1–10 working days to display the funds in your account.

Please contact hello@mermaids-swimwear.com within seven days of delivery, including your order number and clear photographs of the fault. Our team will review the issue and advise you on the next steps.

Please refer to the size guide available on each product page. Individual fit notes are also included where a style runs smaller, larger or differently from our standard sizing.

Please check the fit guidance on the individual product page. If a style is described as a smaller fit or you prefer more coverage, we generally recommend choosing the larger size.

Styles sold as a set are supplied in one selected size and cannot currently be mixed or purchased as separates. If you’re between sizes, please check the individual product’s fit guidance before ordering.

Select your preferred size on the product page and sign up for a restock notification. You’ll receive an email if the style becomes available again. Some limited-edition and Final Sale styles may not be restocked.

Rinse swimwear in cool water after use and gently hand wash using a mild detergent. Dry naturally away from direct sunlight. Avoid bleach, tumble drying, ironing and prolonged contact with chlorine, oils or rough surfaces.

Follow the care label inside your garment. We recommend gentle hand washing and storing delicate or crochet pieces folded to help preserve their shape. Avoid hanging heavy knit or crochet garments for extended periods.

We make every effort to display colours accurately. However, shades may appear slightly different depending on your screen settings, lighting and the nature of the fabric.
