The mix-and-match capabilities of a light blue denim shirt and black chinos ensure they will stay on high rotation. And if you wish to instantly kick up this ensemble with footwear, why not complement your getup with brown suede casual boots? In the colder months, when functionality is critical, it can be easy to surrender to a less-than-stylish getup. However, this getup is a shining example that you totally can stay cozy and remain equally stylish during the colder months. This is an outfit you, as a 30-something Millennial man, can always count on.
