For those whose standards surpass being simply snug, there’s nothing like a stunning coat for instantly advancing an ensemble from average to awesome. This season the devil’s in the details, with epaulettes, high collars, furry trims, belted waists, and bushels of big buttons making sinfully stylish statements. Whether you prefer slipping into shearling, tightening toggles, playing in plaid, or spending your days in the trenches, this winter’s offerings of outstanding outerwear are hot in more ways than one.
