A denim jacket and a turtleneck are the ideal way to introduce some cool into your day-to-day wardrobe. Wondering how to round off this outfit? Rock black leather double monks to dial it up a notch. As you can see, it's super easy to look amazing and stay snug when colder days are here, all thanks to combos like this one. Certainly a great pick if we're talking fashion for 60-something guys.
