Go for a dark green gilet and chinos for a relaxed getup with a twist. You know how to polish up this getup: black leather casual boots. During the colder months, when practicality is above all, it can be easy to settle for a less-than-stylish getup. This getup, however, is a good illustration that you totally can stay cozy and remain stylish in the colder months. This combo is perfect for middle-aged gents.
