One of the coolest ways for a man to style such a hard-working piece as a grey blazer is to combine it with jeans. Rounding off with chelsea boots is the most effective way to bring an extra dose of class to your ensemble. As you can see, it's extremely easy to look awesome and stay cozy come chillier weather, all thanks to ensembles like this one. Rest assured this look is something you can totally wear as a guy in his 60s.
