Forever 21's returns policy varies depending on whether you made your purchase online or in-store. Purchases made online can be returned within 30 days by mail or in-store for a refund back to your original payment method. Exchanges can only take place in-store. To start your online return, head to your account and select the order you wish to return. You'll then be prompted to download and print a returns label which needs to be affixed to the packaging. You can then choose how you want to send your item back. In-store purchases can only be returned or exchanged in-store, again within 30 days of purchase. For any returns, items must be unwashed, unworn, undamaged and with any original packaging intact.
