Great question! The Example T-Shirt uses standard unisex adult sizing. Since it's made of cotton, it's likely pre-shrunk, meaning it shouldn't shrink much after washing. To find your best fit, we recommend checking the size chart provided (if available or contact customer service). Also, consider the "used" condition, as it may have been washed before. If you're between sizes, you might want to consider the larger size for a more relaxed fit.
