So it fits my size zero wife who is 120lbs perfectly. I was about to return it because the seams started ripping when I tried to pull it over my shoulders. I know thermals are supposed to be comfortable, but I couldn't cross my arms comfortably and I'm not a big guy. Sleeves were ok, length was good, everything was ok but shoulders were too tight. I have to wonder if it was a big boy and not a big man. If it was too small I would say go up a size when ordering, but going up a size would mean longer sleeves, a larger neck etc so I don't recommend this unless you have very narrow shoulders .
