I purchased XX-Large and only hoped they were accurate with their sizing charts. Results: spot-on! XX-L was indeed correct for me. I normally purchase size L for my shirts, and a sports coat size I'd wear would be about a size 43. Weight and frame around 180 at 5' 10. For those of you trying to determine what size shirt to purchase, this should help you. I love this shirt, the colors and all.
