We do not offer postal exchanges online. Should you wish to exchange your online purchased item, the original item will need to be returned and another order will have to be placed.
Alternatively, you are able to exchange your order at any UNIQLO UK store if you paid using a Credit/Debit 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 will have to be returned to our warehouse as they will not be accepted for exchange in stores.
Please make sure you print or download your invoice (attached to your shipment confirmation email) as this is needed to process any exchange.
