Amazon billionaire Jeff Bezos' look has changed drastically since he started the company

Amazon CEO Jeff Bezos became the world's richest man for a brief time this week, surpassing Bill Gates.

The tech entrepreneur has changed a lot since he started Amazon in the 90s. 

Bezos wowed Silicon Valley's Allen & Company Sun Valley Conference earlier this month with a surprising physique that was quickly immortalized with memes. His "guns" were the most obvious change, but his shaved head also marked a departure from his previous bookish look.

Bezos also frequently used to wear sweaters over collared shirts - a look that he has now swapped for vests over t-shirts and sunglasses. His slouchy posture is also gone.
