I tried on a dressing room full of items before christmas, and this was the clear winner. i got it in the green xs, which fit perfectly. i am 5'6" and of medium build. the s was slightly too big through the chest and arms - skewed a little too military looking for me. i like the versatility of leaving it open or zipping it up, but like another reviewer, i wish the top lapel would snap back onto the shoulder because it can flop back and that gets a little annoying. overall, i really like the fitt
