I got this for my daughter who is working in NYC.  She had been avoiding getting a down coat because they make you look puffy, but with her new job requiring long walks from the subway, she finally let me buy her one.

She is a shorty with an athletic figure, 5'4" with broad shoulders, and usually wears a size 6 in clothes.  First we tried the small, and although it looked fantastic, it was tight across the shoulders like other reviewers have said.  We were worried about the medium, but it fit beautifully with plenty of room to move.

The belt does need to be tied instead of buckled, but along with the slightly-fitted construction of the coat, it creates good shape instead of looking bulky.  The hood is definitely huge, but fleece-lined and really warm.  We've seen no feathers pop out yet.

This coat is very warm when the temperature is around freezing, and adequately-warm when in the teens.  My daughter layers it over a fleece when it's really cold, and has been just fine on her long walks with the recent wind chills of zero degrees.
