I believe these shirts are smaller than the given measurements. I'm no tailor, but the measurements I get on my Small are:
Bust: 17"
Shoulder to Sleeve: 9"
Shoulder to Bottom: 26"
When I say "shoulder," I'm referring to top of the shirt where the sleeve is stitched to the body.
I'm a skinny dude, and the Small was like a kid size on me. I'm going to exchange it for a Medium or a Large. The material feels great and the shirt looks great, however.
