Display your chops in men's fashion by teaming a beige crew-neck sweater and red jeans for a casual ensemble. Navy suede derby shoes will infuse an extra touch of style into an otherwise straightforward look. When it's one of those dull fall afternoons, what better to spice it up than a sharp ensemble like this one? You can take cues from looks like this if you're 30 and you want to take a more mature approach to your style.
