I really am pleased with this coat.  I was a little wary ordering online.  I ordered a medium.  I'm 5'7" and about 130 pounds.  I think I could have gone with a small, but because I have long arms decided on the medium and the arm length was perfect.  The only reason for the 4 star instead of the 5 is that I think I might take it to the tailor and have the waist cinched a bit more, as there is no way to manually do this on the coat itself.  I live in Bavaria and the weather here is cold and damp right now.  This coat is extremely warm, being down it's light and thin, yet keeps the cold out.  It's a keeper. Love it!!
