Please take a good look at our size chart and  how to measure guide for your item before you order to ensure your clothing items will fit you well. Returns and exchanges cost money and harm the environment with CO2 in transportation, so we want to avoid them whenever we can.

  • Bundle returns will be refunded pro rata

Please also note that we do not reserve the item whilst we wait for your item to be returned to our warehouse and it may be out of stock by the time we process your return.

Return Shipping

  • For the UK/US/EU you can use the provided returns label to send your goods back to us. We will deduct £4.50/$15/€11 from your refund to cover this shipping cost if you choose to use our label.
  • Returns labels are generated at the completion of a returns form and you can choose to either print it yourself or have a collection point print it for you. These options are available when you process your return.
  • Returns labels are provided through Swap and we can only offer free labels when using this service
  • The label must be used within 30 days of generating it. After that period the customer will be responsible for shipping their return through their own chosen courier as we are unable to generate a new one label again for the same order.
  • You can also choose to return items to us using a shipping method of your own choosing, but you will be responsible for the cost involved
  • We do not currently generate return labels for shipments outside of the UK or USA. Customers are responsible for the returns shipping fees including Duty/VAT/Customs fees
