Team a green-yellow sweatshirt with a crew-neck t-shirt to achieve new heights in your personal style. Feeling adventerous? Mix things up by rocking yellow leather high top sneakers. In the colder months, when warmth is above all, it can be easy to settle for a less-than-stylish ensemble. But this ensemble is a good illustration that you can actually stay cozy and remain equally stylish during the colder months. This combo should clear any doubts you had about dressing casually as a gentleman in his 50s.
