A look inside Mark Zuckerberg's power business wardrobe

Fresh from paternity leave, Mark Zuckerberg posted a photo of the first major decision he's had to make since coming back to work: "What should I wear?"

The newly-minted dad's closet is decidedly spartan and monotone, filled with his trademark gray shirts and hoodies.

The Facebook founder's sartorial choices stem from a self-avowed need to streamline his choices on normally busy days.

"I really want to clear my life to make it so that I have to make as few decisions as possible about anything except how to best serve this community," Zuckerberg told Business Insider in 2014.

This streamlining is common to many powerful people, from Steve Jobs to Barack Obama.

"You'll see I wear only gray or blue suits. I'm trying to pare down decisions. I don't want to make decisions about what I'm eating or wearing. Because I have too many other decisions to make," Obama once told Vanity Fair. — GMA News
