A dark brown overcoat looks so classy when matched with navy dress pants for an ensemble worthy of a British gentleman. Spice up this getup with a pair of white low top sneakers. Keep this ensemble ready to go when warmer days are here, and rest assured, you'll save a ton of time brainstorming for what to wear on more than one occasion. A no-brainer for 40-something guys who are looking for age-appropriate clothing.
