Like most DC products I find you may want to get a size down. It could be that I got a lemon pair but the 36" waist was huge. They are really nice though but I decided to return them rather then risk another pair. The stretch would have been nice!
I would recommend this shirt to any tall lanky people. I have such a hard time finding t-shirts that are long enough and don't look like I am wearing a parachute. I have 3 of these shirts large and they fit my 6'6" frame very well. Pretty reasonable even for a Canadian. Woot!
