We've had an unusually cold December in North Carolina, so this coat has gotten a lot of use during the month that I've had it.  I wear a size 8, and I purchased both a medium and large.  The medium was perfect, even with a sweater underneath.  A couple of drawbacks - I wish that the belt was not so long.  My waist is not exactly tiny, but I have to cinch the belt to almost the last hole, and the length of the belt causes it to wrap around to my back.  A bit of a pain to deal with.  I also wish the hood was more substantial.  Overall, however, I love the style, and felt I got a great deal at $80.  The fact that it can be machine washed and dried is just icing on the cake.
