Most 27-year-olds consider a day to be a victory if they eat something other than a frozen burrito for dinner. At the complete opposite end of the spectrum, Olivier Rousteing is designing for one of the best luxury European labels out there, and has been since he was the ridiculous age of 25. Balmain has very quickly and very quietly established itself as a label that understands and speaks to the youth without sacrificing its legacy as a classic luxury house. Rousteing's motorcycle jeans are a favorite amongst both snooty sophisticates and grungy streetwear kids. And if you don't envy the dude yet, just remember that Rihanna went from his biggest fan to his bff in a heartbeat.
