5'9", 175, the medium fits perfect. It's extremely soft and plush, has some stretch (mohair, polyamide and elastane). Not quite as "hairy" as the other mohair sweaters and polos in the fall/winter collection; softer and more plush IMO. My wife liked it so much she got one for herself as well. Have only worn it 2 or 3 times but have gotten multiple compliments on each occasion; works great with jeans and a henley or T shirt. one of my favorite sweater purchases from Todd this winter.
