For reference, I am 5'6, 160 pounds, semi muscular build. I ordered a small in black and it fits me just right – a tailored feel without being too snug, and I'm really picky about the way shirts fit me. The color is deep and rich, very high end feeling, with a medium weight. I especially like that the collar has a little stiffness so that it stands up on its own, even without having the buttons done all the way to the top. The buttons themselves have a very subtle streak of color in them, almost like veins in marble, however they are all the same, not unique to each other. So happy I found it on sale, otherwise would have missed out on it. This thing makes me feel better than everyone. Thanks Todd.
