Loving the way this combo of a dark brown wool blazer and a light blue dress shirt immediately makes you look classy and stylish. Let your outfit coordination credentials really shine by finishing off this outfit with a pair of black leather derby shoes. So as you can see, it's a knockout, not to mention spring-appropriate, outfit to keep in your seasonal rotation. Think it's hard for 20-something gentlemen to perfect semi-casual style? This combo should prove you wrong.
