If the return is due to a mistake on our part (ie. we shipped you the wrong shirt or the shirt has a defect), we will reimburse you for the return shipping costs as long as you use a standard shipping method. If you are returning a shirt because you are not happy with it or want to exchange it for a different shirt, then you are responsible for the shipping costs. Before you ship anything back to us, please email infos@ginkgo-vietnam.com first so we can provide you with complete return instructions. Also, make sure you include your order # in the email.
