Wear a charcoal check overcoat with navy chinos to be the epitome of masculine elegance. Red suede derby shoes will inject an added touch of refinement into an otherwise mostly dressed-down getup. And if you're looking for a cool getup that will take you from winter to spring, this one fits the task well. So if you're looking for outfit inspiration for dressing as you head into your 30s, this pairing is a good example.
