If you'd like take your off-duty style to a new height, wear a navy long sleeve shirt and brown corduroy chinos. Finishing with dark brown leather casual boots is a fail-safe way to add an extra dimension to this ensemble. As you can see here, it's extremely easy to look awesome and stay snug when chillier weather hits, thanks to this look. Definitely a foolproof option when it comes to style for guys in their sixties.
