Bump up your styling game by putting together a navy overcoat and a black wool turtleneck. Take a more elegant approach with shoes and complement this look with a pair of black leather tassel loafers. There's no nicer way to cheer up a dreary autumn afternoon than a sharp look like this one. As a 30-something gent, you probably want to start dressing in a more sophisticated manner. If that's the case, combinations like this become a great source of inspiration.
