One of the coolest ways for a man to style out a dark green gilet is to marry it with chinos in an off-duty combination. Complement your getup with a pair of black boat shoes and ta-da: this look is complete. It's is an appealing option if you're on the hunt for a killer ensemble that transitions easily into fall. This ensemble should inspire anyone who had doubts about donning casual outfits as a 40-something gent.
