5'6" 140 lbs. Bought size Medium, color White. Definitely slim fit, which is fine with me. The shirt is fine, although I wish I'd bought a different color. The white is a bit weird. It seems to pick up and reflect colors from around it, especially reds, so the shirt seems to have an almost pinkish hue a lot of the time. I thought it was just me, but my wife mentioned it also. Still, it fits well and seems like decent quality for the money. I'd buy it again, just not the white.
