Best of the Best 2013: Men’s Fashion: Fall Staple: Brunello Cucinelli

Every season has its must-have item—a piece that both updates a man’s wardrobe and blends seamlessly into it. This fall it is Brunello Cucinelli’s reversible cashmere vest. Cucinelli has made the vest a personal trademark for years, layering it over a sport coat for a casual edge or wearing it more conventionally over a shirt and slacks. Now a growing flock of followers is picking up his easygoing style and wearing the vest in myriad ways, such as this version in wool, cashmere, and silk ($3,185) layered over a sport coat and dressed up with a pocket square.
