Custom belt buckles can be fashion-forward, provided they're moderately discreet. A giant brass one that reads "Open With Care: Contents May Explode" is not what we're talking about. These guitar-neck belt buckles ($95, gorillavinyl.com) are made from the fret boards of vintage guitars and contain just the right amount of novelty, presented in an understated way. In other words, they're the kind of awesome that doesn't need to shout.
