Facebook CEO Mark Zuckerberg turns 29 on Tuesday. What do you buy a billionaire for his birthday? May we suggest some new clothes? As this gallery demonstrates, the young tech titan is famously known for his limited (some might say monotonous) wardrobe. KIMIHIRO HOSHINO/AFP/Getty Images
As a baby, little Mark had to wear whatever his parents dressed him in -- thus this powder blue outfit. He's been striking a blow for personal fashion freedom ever since. Getty Images
Zuckerberg is best-known for his iconic hoodie, which even has its own mock Twitter accounts. But that may not be the most favored item in his closet. Stephen Lam/Getty Images
Zuckerberg has become partial to this gray Facebook T-shirt, adorned with three small icons that grace every user's Facebook page. Getty Images
Mark has worn the shirt for numerous Facebook events and announcements, like this one. CNN

Zuckerberg did clean up his act when President Barack Obama visited Facebook headquarters in April 2011. His suit and tie were so rare, Obama even made a joke about it. MANDEL NGAN/AFP/Getty Images
But when Facebook went public on May 18, 2012, Zuckerberg was back to his hoodie-wearing ways. Zef Nikolla/Facebook
No doubt to her great relief, Zuckerberg dressed up for his wedding to longtime girlfriend Priscilla Chan on May 19, 2012. No word on whether he rented the suit. Mark Zuckerberg/Facebook
Zuckerberg faces many questions as he ponders his fashion future. Can a tech CEO still wear T-shirts and hoodies to business events at 40? 50? Probably. But let's hope Priscilla took him shopping for his birthday. Josh Edelson/AFP/Getty Images
