Facebook CEO Mark Zuckerberg has worn the same thing every day for nearly a decade, but he switched it up recently at Facebook's annual developers conference, F8.
His new style is still hyper-minimalist, but is slightly more stylish than his signature look of jeans and a gray t-shirt.

Elon Musk, CEO of Tesla and SpaceX, has high-end taste: He's been known to wear a blazer from designer Alexander McQueen, and he doesn't shy away from a tuxedo.
To get Musk's more casual look, though, all you need is a cool graphic t-shirt and practical-yet-stylish leather boots.
Angela Ahrendts, Apple's head of retail, worked in the fashion world before joining Apple. She's almost always wearing a cool jacket (although her signature look is a Burberry trench coat).
Much like Bezos, Ahrendts has taken a liking to leather bomber jackets. While Ahrendts' version is likely out of most peoples' budget, you can find a similar version for around $100.
