Marry a long sleeve t-shirt with charcoal jeans for an everyday outfit that's full of charm and personality. And if you wish to immediately step up this ensemble with one single piece, complement this look with oxford shoes. In winter, when warmth is everything, it can be easy to surrender to a less-than-stylish look. However, this look is a clear example that you can actually stay warm and remain equally stylish in winter. This outfit looks great on mature guys.
