A navy blazer and khaki chinos are absolute staples if you're piecing together a semi-casual closet that matches up to the highest menswear standards. A pair of high top sneakers will add a little edge to an otherwise mostly dressed-up look. Keep this outfit in your front hall wardrobe when spring comes, and we guarantee you'll save a lot of time trying to pick out an ensemble on more than one occasion. All in all, a smart idea if we're talking dressing ideas for mature guys.
