I cannot believe how much I like this coat!  I had previously purchased a different wool coat (not Calvin Klein) - when that one arrived, I was not "wow"ed, did not care for the sewn-in knit neck collar, and returned it.  When I pulled this one out of the box, I immediately saw the high-quality (and for a very reasonable price).  I wear either a Large or Extra-Large (I'm 5' 10", 235 lbs), depending on the coat.  This one is just a bit large, but I suspect the Large would have been restrictive in the arms/shoulders.  It has a light lining, which I prefer.  (With a 6 minute walk from my car to desk, I have not felt chilled in 22 degree weather.)  I can wear a bulky sweater with this coat and be comfortable driving.  I tend to be picky about coats and jackets - I am extremely pleased with this purchase.
