In situations comfort is a must, this combination of a blazer and cargo pants is a winner. Complete this outfit with a pair of dark brown leather casual boots to pull the whole ensemble together. In winter, when comfort is prized, it can be easy to surrender to a less-than-stylish ensemble. But this ensemble is a clear example that you totally can stay comfortable and remain equally stylish during winter. Definitely a foolproof option if we're talking style for 30-something gentlemen.
