When you're looking to have your t-shirt examined for authenticity in our forum - please include as much of the following information with your post as you can:
Photo the front
Photo of the back (if there's a print)
Photo of the tag or collar
Photos of the arm and bottom hem
A high-quality closeup of the print
Measurements (IN INCHES) of the pit-to-pit and length
This will help our community get the information they need to make the assessment.
Cheers!
