Almost Perfect!
This one's a beaut! It is definitely a full fit, so I reco. sizing down. I'm 5'11' and 160 with a slim/athletic build and got an XS. The color is accurate to the online images, and the feel is amazing, but I gotta take one star off because it's a too wide across the chest/waist. If you're looking to layer it over a spring or fall sweater, it's perfect though. That said, the shoulders and arms are the perfect width and length.
