Your order can be cancelled as long as it's not being prepared.
To request the cancellation of your order, select Order > Cancel order in the contact form. Please also remember to specify your order number, so that our team can process your request correctly.
It won't be possible, however, to modify a product or a size inside an order. We recommend you request the cancellation of your order and make a new purchase with the correct item(s) as soon as you have received the refund for the cancellation. Please note that if you have just placed an order and forgot to include a product, you will need to place a new order for its purchase.
