Mark Zuckerberg In A Suit And Tie (PHOTOS)

Mark Zuckerberg shed his trademark hoodie, t-shirt and jeans during a trip to France this week in favor of something fancier.

The Facebook CEO instead donned a suit and tie--a rare event--to meet with French President Nicholas Sarkozy and to speak at the France G8 Summit. During the e-G8 conference on Wednesday, however, Zuckerberg took the stage in his usual uniform: a gray t-shirt and jeans.

Zuckerberg wore a blazer, but kept the jeans, when he interviewed Obama at the Facebook headquarters. Obama joked at the time, "My name is Barack Obama, and I'm the guy that got Mark to wear a jacket and tie."
