A denim jacket and navy wool chinos are absolute menswear must-haves if you're piecing together a casual wardrobe that holds to the highest sartorial standards. Break up this look with a pair of white and black high top sneakers. So as you can see, it's a dapper, not to mention spring-friendly, ensemble to have in your seasonal arsenal. Overall, a good example of off-duty style for gents in their forties.
