We are sorry for the confusion regarding your t-shirt, as it arrived with the design on both sides while you expected it to be on the front only. Upon review, we found that the design file submitted included artwork for both the front and back. To help avoid this in future orders, we recommend carefully reviewing both the on-screen preview and the downloadable PDF proof before finalizing your purchase, as these tools provide an accurate representation of how your design will appear in print. You can learn more about these features here: https://www.vistaprint.com/customer-care/help-center/360052259371/?swsquery=pdf%20proof&querycat=helpcenter_search_dropdown Additionally, you’re welcome to adjust your design and place a new order at your convenience. We hope this guidance is helpful.
