Not only is this coat very warm, but it's also really cute. I had been searching for a down coat that didn't make me look enormous. The belt on this really helps, and especially if I leave the top unzipped a little bit so that my bright scarf can be seen. The hood is large and doesn't really stay over my head in windy weather unless I tighten it, but I usually wear a hat anyway. I'm 5'5 150 lbs and I ordered a medium since I had othered another one from this site in large and it was too big. The medium is perfect, even under thick sweaters.
