We love how this combo of a double breasted blazer and a waistcoat immediately makes any guy look smart and classy. During the winter months, when comfort is everything, it can be easy to surrender to a less-than-stylish ensemble in the name of practicality. This ensemble, however, is a vivid example that you can actually stay comfy and remain equally stylish during the winter months. So if you need dressing tips for guys in their sixties, this ensemble is a perfect example.
