In a 2014 interview, Facebook founder Mark Zuckerberg shared why he has this habit.

There is a special reason behind Mark Zuckerberg’s habit of wearing gray T-shirts.Although the person who asked this question expected Mark Zuckerberg to answer humorously, he responded very seriously. He said choosing simple clothes, even having no other options in his wardrobe, allows him to focus more on work.

Mark Zuckerberg replied: “I want my life to be simple, with as few decisions as possible, except serving the community.”

Zuckerberg said his wardrobe has about 20 identical gray T-shirts.

He added: “I’m really lucky to be in the position I am in now. Every day I wake up and serve more than 1 billion people.”

He revealed that even the smallest decisions like what to choose or what to wear in the morning can take up unnecessary energy.

Zuckerberg added: “I feel like I’m not doing my job well if I spend energy on silly or frivolous things in life.”

Nearly a decade has passed since this Q&A, it seems that Mark Zuckerberg is still very loyal to his simple but special wardrobe.

On a few rare occasions, people saw him wearing a number of outfits such as a navy blue round-neck long-sleeved shirt, a beige boxy shirt, a khaki sweatshirt, and even a sweater. In important meetings with the government, he wears a suit instead of his usual gray T-shirt.

However, when mentioning Mark Zuckerberg’s outfit, people will immediately think of the “combo” of jeans and a gray T-shirt. This is the unique characteristic of the founder of Facebook.
