As long as your order is not yet being processed for shipping, you can change it yourself in your account: add or remove items, choose a different size, change the quantity or update the delivery address. Your account shows whether that is still possible; once your order is in the shipping process, the option disappears.
You can only change the delivery address yourself within the country you paid shipping for. Want delivery to a different country? Email us as soon as possible with your order number and the new address. As long as your order is not yet being processed, we change it for you; you then pay the difference in shipping costs.
Is your order already being processed or shipped? Then we can no longer change anything. With PostNL you can often still choose a different pick-up point or delivery time via the track and trace. An item that is not right can be returned or exchanged for another size after you receive it.
