The Perfect Shirt
I'm 5' 9" with an athletic build and purchased a Medium. The shirt fits absolutely perfectly. I've bought 3 of them and they all fit the same so no quality control issues with sizing. Very soft and heavy fabric. Good for any occasion.
Rated 0 on a scale of minus 2 to 2, where minus 2 is Runs Small, 0 is Fits Great and 2 is Runs Large
