The sartorial arsenal of any discerning gent should always include such wardrobe heroes as a navy suit and a white dress shirt. Serve a little mix-and-match magic by slipping into a pair of navy suede loafers. As you might be rightly thinking, this is a cool choice when spring comes. As you slip into your 30s, you want to start dressing in a more elegant manner. That's when looks like this become a great source of inspo.
