“The young-tech-start-up-dude-look–the type who doesn’t care about his appearance–is fairly played out and doesn’t inspire much confidence in business. With billions at his command and a credit to shaping the future of communication, Zuckerberg should look the part. Half of me wants to see him do a complete 180 with some Rick Owens and start shopping at Atelier, but he’s best fit to a suit with his responsibilities. Billy Reid would be a good match for him, it’s approachable but doesn’t read too old or ‘captain of industry.’ Of course, he just has to make sure it fits.”
