Since this T-shirt is one size fits most, based on the "Lithograph - Height: 9" x Width: 12"" dimensions, it may run slightly smaller or tailored fit. We recommend checking the provided measurements against a shirt you already own to ensure a good fit. Because it's a used t-shirt, it has possibly already been pre-shrunk, so it should be fine. If you have any further questions about the size do not hesitate to ask us.
