Thank you so much for sharing this detailed and constructive feedback! We're glad you found the perfect fit with the XXXL Port Authority shirt, and you've highlighted a really important point—sizing can vary significantly from brand to brand. Your advice to be careful when ordering is a great reminder for everyone. For that exact reason, we always recommend checking the size chart on each product page. As you noted, it's the best way to ensure a great fit. A helpful tip is that the measurements shown in the chart reflect the size of the garment itself, not the wearer. The best way to use it is to measure a shirt you already own that fits well and compare those measurements to our chart. We're so happy the new shirt fits you perfectly, and we truly appreciate you taking the time to help other shoppers!
