If you are ordering to the UK or Europe, you will not be liable for any customs or duties. For any international destinations, the usual customs and duties will apply.

There will be no extra duty or customs charges to pay on your orders delivered to the EU or UK.

The usual duty and customs charges apply to orders delivered to other destinations.

You are welcome to return items from different orders in one parcel.

Please make sure that you clearly note each item with its respective order number so our returns team can process your refund without delay.

If you have any further questions, please do not hesitate to contact us here.

You can return an item within 100 days of receiving your order if for any reason you're not completely happy with it.

Items should be returned in the same condition in which you receive them: the original product packaging and tags must still be attached, and the products must be in an unused condition (except in the case of products which you have discovered to be faulty upon use) - please contact us and be sure to select 'Faulty product' from the query topic dropdown.

You are responsible for the cost of returning your order back to us. You can do so using any courier of your choosing, but please note that in this case we will not refund any postage fees (except if the goods are faulty or if you have received a wrong product).

If you no longer have your packing slip to enclose inside your parcel, please contact us.

To make sure everything gets back to us safely and promptly, you cover postage costs to return an item.

Once we've received your item(s) back we will process your refund within 10 working days.

It's simple to set up a return for all or part of your order.

Please fill out our Returns form and our customer service team will get back to you with further instructions.
Please see our refund policy here.

We know sometimes you don't find the perfect size, colour, or style the first time. If you want to exchange your item, we ask you to:

• Return the item(s) by initiating a return here.
• Find the new item and purchase that as a new order.

If something's not right with your item we aim to process your return and refund as quickly as possible so you can get back to finding great products. It normally takes between 5-10 working days for us to process your refund once we've received your return.

If you're concerned about your refund, please get in touch with your order number and returns tracking number, so we can investigate the delay for you.

If you haven't received your refund it is most likely because we haven't received and/or processed your return yet. Please note it normally takes 5-10 working days for us to process your refund once we have received your return.

Please contact us with your returns tracking number if it's been more than 10 working days so we can investigate.

If your item is faulty upon receiving it, please get in touch to receive a free return.

If you have problems with the item after using it, please get in touch as soon as you notice the problem and we will assess the fault. You just need to give us a few details:

• Your order number
• Images of the complete article and area of the fault. These will need to be sent separately. Please reply to the auto-response email you receive after submitting the contact form.
• Details of the problem you noticed and how it first occurred.
• Any other information, e.g. has it been washed/dried, and if so, how?

If your claim is accepted, we will either arrange a refund or a replacement if we have stock available.

Please see our estimated order delivery dates here.

If you would like to make changes to your order, such as a size change, please contact us as quickly as possible, and be sure to select 'Editing an order' from the query topic drop-down. Please note, we cannot guarantee this will be possible once your order is processing.

Unfortunately, we can't add another item to an order once it's already been placed.

However, if you place an additional order and then contact us with the order numbers, we will refund you the 2nd shipping fee.

Please note we can only do this for orders within the EU.

Please contact us as soon as possible using the contact form, and be sure to select 'Editing an order' from the query topic drop-down. Please note, we cannot guarantee this will be possible once your order is processing.

Order cancellation, before shipment, may be possible.

We will do our best to make any updates requested, but please be aware that if your order is already processing at our warehouse, we can't guarantee that our request will reach them prior to dispatch.

If your order has already been shipped or delivered then you can follow our straightforward steps to Return all or part of your order. Once we receive your return, we will refund the price paid for the goods to the original payment method used.

We may have sent your items in separate parcels. Please check your dispatch confirmation or your account for more details.
