As long as your items have not shipped you can edit your order and change your shipping address.
Simply visit your Order Confirmation Email and you'll see a link that says "Edit or Cancel Order" at the bottom of your email. 😍
P.S. Keep in mind, if you'd like to make adjustments to your order to do so as soon as possible, because once your order has shipped edits cannot be made.
Hope that helps! 💕
