A light blue long sleeve shirt and khaki chinos are a pairing that every style-savvy gent should have in his casual styling collection. Get a bit experimental on the shoe front and introduce dark brown leather casual boots to the equation. So if you're looking for an outfit that's seriously stylish but also entirely spring-appropriate, this one is great. So if you're scouting for fashion tips on how to dress as you head into your 40s, this pairing is a perfect example.
