Returns for online orders including orders placed with a gift card will have to be returned to our warehouse using the Returns Portal as they will not be accepted for return in stores. Alternatively, you are able to exchange your order at any UNIQLO UK store if you paid using a Credit/Debit/Gift card or Apple/Google Pay. You may only exchange for the same value or more as we cannot offer a partial refund.
