This combination of a dark brown overcoat and charcoal plaid chinos is hard proof that a safe look doesn't have to be boring. If you want to immediately step up this outfit with one single item, why not introduce charcoal suede chelsea boots to this outfit? On not-so-bone-chilling days, wear this easy-to-transition look and look absolutely awesome. This is a good-looking yet age-appropriate ensemble for a 30-year-old man.
