I'm 5'7, 164 lbs got this coat in large, Ruby and it fits perfect! I wasn't sure of what size to get... having a larger chest I was afraid it would possibly pull on the buttons or look weird. But it didn't! I even have some extra room to wear a thin sweater under. It is very well made. I was looking for a coat that i could button all the way up my neck to keep me warm when it's cold and also put down for when it's not so cold and this coat was the one. Its very warm. I really have no complaints. Also, reviewer shoegurl said that there are no pockets, but she is mistaken. There are pockets hidden in the front pleats of the coat!
