Wrongly ordered sizes won’t be eligible for refunds. We print on-demand and only produce items we get an order for, avoiding textile waste from overproduction. Requesting a size exchange would mean producing an entirely new product. If you choose to exchange for a new size you would need to place a new order at your expense in another size. Make sure you read the size charts available on all product pages before placing your order. They are accurate and very helpful. If for any reason you are unsure about your size or can't locate the size charts on the product page, please contact us with any questions you may have. We are here to help you 24/7.
