My ectomorphic friend found that at 45 degrees this handsome, tapered-fit coat did not quite keep her warm. Indoors it's as nice or nicer that a sweater.
Fit was good, although of course that will vary. This jacket was well sewn.
A problem was the cuff seam location; the bump right under the wrist bothered her typing.
The zipper was fine, mechanically, although the pull tab could have been bigger.
This really looks good on a slim person.
