This relaxed casual combination of a denim jacket and a dark brown long sleeve shirt is super easy to pull together without a second thought, helping you look seriously stylish and prepared for anything without spending a ton of time searching through your wardrobe. We love how cohesive this outfit looks when completed by brown suede casual boots. A wonderful example of transitional style, this getup is ideal this spring. All in all, a savvy pick when it comes to dressing ideas for 30-year-old guys.
