The house that Pharrell built covers so much ground that we considered making it two entries. But on the real, his astronaut-inspired line just rang in its 10th anniversary, and is also poised to make billions of dollars after a recent expansion. It doesn't hurt to have industry heavy-hitters in your corner, like Jay Z and menswear designer Mark McNairy.

Many streetwear labels have attempted to make the transition into higher end menswear, but thanks to McNairy, BBC's Bee Line takes the playful brand up a notch without losing any of its trademark whimsy. Trippy patterned varsities and contrast button blazers abound, and Pharrell is a staunch brand ambassador—he can't stop wearing some of the pieces himself.
