Complement your outfit with a pair of white leather low top sneakers for extra style points. Picking out a neat look can be challenging on its own. Enter subzero temps into the equation, and the whole thing becomes all the more difficult. Don't despair, this here is your wintry style inspo. When it comes to casualwear for guys in their thirties, this combo looks great on most men.
