I am 5' 10 and 175 lbs with an average build. These shirts are very comfortable. The only reason that I am giving it 4 stars instead of 5 stars is because the shoulder seam is about an inch below where my shoulders end, so the seam is on the upper part of my arms and not on the top of my shoulder. I do not have small shoulders, nor broad shoulders. Just average. The buttons are positioned perfectly, so that either 1 or both buttons can be fastened and it still looks good without showing to much chest for professional wear.
