A dark green wool blazer and brown dress pants are a classy outfit that every dapper man should have in his collection. Dark brown leather loafers are a nice option to complement your outfit. So if you're in search of a cool ensemble that transitions easily into spring, you found it. This ensemble is probably what you're looking for as a 40-something.
One of the best ways to style out such a hard-working menswear piece as a light blue ombre crew-neck sweater is to pair it with brown dress pants. If you need to immediately perk up your look with a pair of shoes, introduce a pair of dark brown leather loafers to the equation. As the weather gets warmer, it's time to shed those bulky winter clothes and opt for a look that's lighter, like this one here. As you see here, as a middle-aged guy, you have a vast array of outfit options.
