We love how this pairing of a cable sweater and charcoal dress pants immediately makes a man look stylish and polished. For shoes, you can take a more elegant route with a pair of oxford shoes. During the colder months, when warmth is imperative, it can be easy to surrender to a less-than-stylish outfit in the name of practicality. However, this outfit is a vivid example that you totally can stay snug and remain stylish in the colder months. This one is a modern yet age-appropriate combination for a man in his 30s.
