While Facebook privacy settings are constantly changing, the same can’t be said about Mark Zuckerberg's style. In an interview with the TODAY Show, the CEO revealed that he owns 20 or so of the exact same gray T-shirt. And while some men use one drawer for socks alone, Zuckerberg uses just one drawer for everything. With the money he has, he can probably buy a nice little suit from Dior, but apparently there’s some unwritten dress code in Silicon Valley where these tech gurus are modern-day Doug Funnys. Even Steve Jobs had hundreds of black mock turtlenecks made by designer Issey Miyake so he could wear the same thing everyday.
