You may have had "Blurred Lines" and "Get Lucky" stuck in your head all summer—and, yes, it's time to talk about Pharrell again. In addition to music, the multi-hyphenate has his hands squarely in the cultural cookie jars of fashion and style. He's the cofounder of the clothing brands Billionaire Boys Club and Ice Cream Footwear, and has designed accessories for Louis Vuitton. And he's working on an environmentally friendly material and manufacturing process known as Bionic Yarn to make style more green. But it's perhaps his fearless personal style—from streetwear cool to red carpet dashing—that inspires us most of all.
