In the interview, Zuckerberg reveals something long suspected about him, that he owns multiple t-shirts of the same color so he doesn’t have to worry about what to wear.
‘I mean, I wear the same thing every day, right?' said Zuckerberg. Asked by Lauer if he owns 12 of the same gray t-shirt, Zuckerberg admitted it was more like 20.
Zuckerberg also revealed that he doesn't get much closet space at home, which is mainly used by wife Priscilla Chan.
Instead, Zuckerberg's identical t-shirt collection live in the one drawer that he gets to use. ‘Like men everywhere,’ said the 28-year-old millionaire.
In the interview, which was filmed last week but airs on Thursday morning, Zuckerberg also talks about the future of Facebook, his daily routine and his wedding to his college sweetheart last May.
Zuckerberg's rather basic wardrobe isn't so unusual within the technology sector, the late Apple co-founder Steve Jobs was infamous for his black turtlenecks and Levi's 501 jeans, while his successor, Tim Cook favors a black, long-sleeved shirt.
At the time of Facebook’s IPO, Zuckerberg's more casual sense of style was heavily criticism and he was accused of being ‘too immature’ to run a large corporation.
These days sightings of Zuckerberg in a suit are becoming more and more regular as he mixes with world leaders.
Currently in Russia, he met with prime minister Dmitry Medvedev on Monday, to help boost the social network's presence in the country and scout for new talent.
In a nod to the seriousness of the occasion, Zuckerberg dropped his hooded top, jeans and trainers ensemble in favor of a dark suit and tie.
Zuckerberg said the main reason for his Russian visit was to attend the Facebook Hack in Moscow, an event where programmers compete to create the best new applications, and acknowledged he liked the Russians' abilities.
According to a report by Renaissance Capital last year, Facebook is only the number four social networking site in Russia with five million users, compared with 21 million for VKontakte.
