French fashion designer Olivier Rousteing went from relative obscurity to fashion superstar when he took the helm as creative director of Paris fashion house Balmain at the age of 25. Now Olivier is living in style, sharing shots of his jet-setting life with over 4M Instagram followers. His couture sensibility and innovative looks are right at home among his celebrity friends, from @kimkardashian and @kendalljenner to @beyonce and @justinbieber. Those high-profile pals helped Olivier raise @Balmain’s profile too, with his celeb-studded selfies pushing the label’s own Instagram account over the 6M follower mark in 2016. At just 31 years old, Olivier Rousteing’s star is still on the rise.
