I bought this jacket as a replacement for a Medium I ordered that was WAY to big. I am 5'1" and about 110lbs. The medium was HUGE! The size was a M 8/10. The 8/10 part was what should of been put in the description. But I got the Small and it is a 4/6 which is plenty big for me. This jacket is NOT for a tall girl at all. The sleeves will be way to short. On me the sleeves are right at my wrist so I cant stick my hands in the actual sleeve which I tend to do a lot. But the sleeves on the Medium were the same length. This jacket fits me at mid hip and it has shape. It is not boxy. It is fleeced from seam to seam including the hood and the sleeves. I wore it in 30 degree weather and my arms, back and torso were nice and warm. I love this jacket. It's so soft that I could fall asleep in it. I cant tell you how happy I am with this jacket. I wear hoodies daily and this is by far the nicest one.
