We give a huge thumbs up to this combination of a dark green military jacket and a turtleneck! Finishing off with beige athletic shoes is a fail-safe way to add a touch of stylish casualness to this look. This one is a modern yet age-appropriate combination for guys in their forties.
So as you can see, it doesn't require that much effort for a man to look on-trend. Try pairing a dark green military jacket with a turtleneck and you'll look incredibly stylish. And if you need to effortlessly elevate this look with shoes, complement your outfit with a pair of black leather derby shoes. As you can see this combo is something you can totally wear as a 40-year-old man.
