Thank you for shopping with us. We're so grateful for every order, and we want you to be completely happy with your purchase. If for any reason you're not, here's everything you need to know.

By making a purchase from Mia Swim, you confirm that you have read and agreed to this policy. This does not affect your statutory rights.

Return window

You have 14 days from the day your order is delivered to let us know you'd like to return.

Your return must then be delivered back to our returns address within 14 days of letting us know. The address is on the A4 packing slip inside your parcel.

Returns received outside this period won't be eligible for a refund to your original payment method.

Eligibility:

To be accepted, all items must be:

• In their original condition: unworn, unwashed, with all original tags, the hygiene sticker and packaging intact
• In saleable condition, with no stains, signs of wear or smells. We check every return, and if any of these are present, your return won't be accepted.
• Returned with proof of purchase (your order number or the A4 packing slip from your parcel), so we can find your order and refund you quicker

Please wear underwear when trying on bikini bottoms. Take extra care if you wear fake tan, and remove any jewellery that could snag the fabric.

We reserve the right to refuse any return that shows signs of wear or doesn't meet these conditions.

Non-returnable items

• Items without their hygiene sticker and tags attached can't be accepted. We'll need to send them back to you, and you'll be required to cover the postage.
• Earrings can't be returned for hygiene reasons. If yours arrive faulty or damaged, we'll send a replacement.
• Final Sale items are eligible for store credit only.

How to return

Step 1: Fill in your slip
Find the A4 packing slip located in your parcel with your order details on. Circle the item(s) you'd like to return, and why. Make a note of the returns address on the slip.

Step 2: Pack it up
Place the slip back in your parcel. Make sure all tags and hygiene stickers are intact, then seal it using the returnable strip on the back of the mailer.

Step 3: Post it back to us 
Drop it off at your local Post Office, ideally using a tracked service such as Tracked 24 or Tracked 48. The returns address is on your A4 packing slip.

Step 4: Keep your tracking number
Hold on to your tracking number and wait for your parcel to be delivered back to us.

Return shipping

• You are responsible for the cost of returning your items.
• Please return via Royal Mail only. As we operate a PO Box, returns sent via InPost, Yodel, DPD, DHL, Evri or Relay may not reach us.
• You're responsible for your return arriving safely. If it's lost on the way back to us, we won't be able to help, so we strongly recommend a tracked service.

Inspection & approval

Once your return arrives, we'll inspect it to make sure it meets all the eligibility conditions above. To qualify for a refund or store credit, items must be unworn, undamaged and in their original condition.

We'll email you once your return has been approved or rejected.

Original shipping charges, exchange shipping fees, duties, taxes and import charges are non-refundable.

Exchanges

We offer one free exchange per order for orders placed in England, Scotland and Wales only.

To exchange, simply email info@mia-swim.com with:

• Your order number
• The item(s) you'd like to exchange
• The new size you need

How exchanges work

Your original item must be delivered back to us and inspected before we can send out your new size. 

Please make it clear on your packing slip that you're exchanging, and write the new size you need. Exchanges are inspected as a priority.

Once your item has arrived, please allow 1–2 working days for us to inspect it and send out your new size.

Going on holiday or need it sooner? We recommend placing a separate order for the size you need, so you're not left waiting.

Still not quite right?
If your new size doesn't fit, please return it using our returns process above for store credit only. We can't offer a second exchange, so you'll need to place a new order.

Refund Processing & store credit

Once your return is approved, please allow around 7 working days for it to be processed. How long it takes to appear in your account depends on your bank.

Choose store credit and you'll receive your approved return value plus an extra 10% bonus, minus original shipping costs or any other non-refundable charges.

We don't cover the cost of return postage or original shipping.

Customs, duties & taxes

Customs duties, taxes and import fees may apply to orders shipped outside the UK, depending on the destination.

Ireland: All duties and taxes are calculated and paid at checkout. Nothing extra is due on delivery.

United States: All duties and customs charges are calculated and paid at checkout. Nothing extra is due on delivery.

All other countries: Duties, taxes and import fees are not included in product prices or shipping costs, and are the customer's responsibility. We can't advise on amounts, as these vary by weight and country.

If a parcel is refused because of unpaid duties or taxes and returned to us, we may deduct the original shipping, return shipping and any customs charges from your refund or store credit.

By completing your purchase, you acknowledge and accept responsibility for any customs charges, duties and taxes as set out above.
