This off-duty combo of an olive raincoat and a black turtleneck is a goofproof option when you need to look casually dapper in a flash. Finishing off with white canvas high top sneakers is the simplest way to introduce a hint of stylish casualness to your look. Seeing as it is getting chillier every day, this ensemble is a smart option for the transitional season. All in all, an ideal example of off-duty style for 30-something guys.
