Yes, you are able to refund your purchases even if you have paid with a gift card. Please review UNIQLO EU’s returns policy here: Return Policy
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 store (within the same country of purchase) 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. Orders placed using PayPal or Klarna (including in combination with Gift Card) will have to be returned to our warehouse as they will not be accepted for exchange in stores.

Where one or more of items purchase by Gift Card(s) only are returned, the balance of the original Gift Card shall be updated by the value of the refund due for the returned items.
Where a purchase has been made using a combination of payment methods (one of which is Gift Card), any refund due shall first be processed on the payment method other than the Gift Card. Should the value of the refund due exceed the amount paid with method other than the Gift Card, such remaining amount shall be refunded to the original Gift Card used.
