I ordered a double x in black thinking it might be coincidence as today's sizes seem to be everywhere. I'm 5ft 11" and 233lbs and the shirt fit well and wasn't loose at all. I like to tuck shirts in, and there's not much to tuck them in, so I might have to wear them outside. For the price paid I'm not complaining.
