One of the best ways for a man to style out a navy denim shirt is to wear it with brown chinos in a casual getup. You could perhaps get a bit experimental in the footwear department and lift up your outfit by rocking a pair of black leather casual boots.
Look sharp yet comfortable by opting for a navy denim shirt and brown chinos. Let your sartorial credentials really shine by finishing off your look with white and black leather low top sneakers.
