I'm 6'2 and 220lbs with an athletic build.
My original order was for a standard fit men's L shirt. The collar on this shirt was much too tight and the body was a touch on the baggy side. This was still the most comfortable shirt I've ever worn to work.
My following order was for a men's XL-slim and this shirt fits great. It's extremely comfortable and while it isn't perfectly non wrinkle it looks sharp with a quick steam. I've yet to spill coffee on myself but I will say I cut myself shaving before work and the stain did come out with a little cold water.
Very happy with purchase and will absolutely buy again.
