A denim jacket and a white and black short sleeve shirt are the kind of off-duty essentials that you can wear for years to come. Switch up your look with a more refined kind of footwear, such as these black leather tassel loafers. During winter, when warmth is the priority, it can be easy to settle for a less-than-stylish ensemble. But this ensemble is a good illustration that you totally can stay warm and remain stylish in winter. A safe bet for 30-year-old guys after a more professional look.
