What Mark Zuckerberg Looks Like All Dressed Up

Mark Zuckerberg is famous for something other than Facebook: his wardrobe. More specifically his love of hoodies and gray T-shirts.

On Thursday, during a public Q&A, someone asked him why he always wears the same gray T-shirt. In truth, he doesn't. He's got a few that all look the same and he always wears them just to have one less "frivolous" decision to make every day - what to wear - he says.

So it's a rare event to see him all dressed up, much less in a suit. But on Sunday, flanked by actor Benedict Cumberbatch, Zuck was on hand to present the awards for the the Breakthrough Prize, an annual $33 million jackpot awarded to a dozen top scientists, sponsored by Facebook.

Besides Cumberbatch, the two other men in the photo are two of the math prize winners, Simon Donaldson and Maxim Kontsevich, Zuck said in his Facebook post about the event.

The awards ceremony is supposed to associate STEM vocations with glamour like a Hollywood ball. So it was a black-tie affair. Zuck didn't go quite that far. He's wearing a straight tie. But that is definitely a suit.
