This was sold out in an xs when i first saw the email. i ended up seeing in my local retailer store and tried on my usual xs. i am 5'3" with a longer torso and about 108 pounds. my chest size is 32c and the xs was just too tight. it buttoned up beautifully and the length was as it is on the model, even though i am much shorter. however, when i tried to move my arms, the jacket constricted all movement. this is a huge disappointment and i imagine going to be an issue for many girls who order online
