To look like a proper gent at all times, reach for a charcoal herringbone overcoat and a light blue dress shirt. For something more on the classier side to round off your ensemble, introduce a pair of dark brown leather oxford shoes to the equation. Keep this look ready to go when spring sets it, and we promise you'll save time racking your brain for an ensemble on more than one morning. As a 30-year-old gentleman, you probably want to start dressing in a sleeker manner. In this case, combos like this are a real lifesaver.
