Such pieces as a tan crew-neck sweater and a white dress shirt are the ideal way to inject a dash of masculine sophistication into your daily fashion mix. For something more on the casually cool end to finish off your outfit, complement your outfit with black leather work boots. In the winter months, when comfort is paramount, it can be easy to surrender to a less-than-stylish getup. But this getup is a bright example that you totally can stay toasty and remain stylish in the winter months. A no-brainer ensemble proper for gentlemen in their 20s who prefer sleeker combos.
