When the setting allows off-duty dressing, make a brown plaid blazer and navy jeans your outfit choice. You could perhaps get a little creative in the shoe department and polish up your ensemble by rocking a pair of brown suede casual boots. Crafting a well-coordinated outfit can be tricky on its own. Add below-freezing temps into the equation, and the whole thing becomes all the more difficult. No worries, this here is your wintry inspo. As a 30-something gentleman, you probably want to start dressing more maturely. In this case, ensembles like this are a safe option.
