Billionaires dressing badly: The Silicon Valley style crisis

The tech world has grown up a lot. So why do its biggest stars insist on dressing like slovenly teenagers? At the annual Macworld and CES conferences in January, a parade of visionary executives will take to the stage to tout their amazing new products. And yet it seems that to show off tech tools, you have to dress like one. These entrepreneurs will look more like college students on laundry day than the titans they are. They’ll wear ill-fitting jeans and shapeless button-downs. Sure to be present in abundance: the hoodie, most famously associated with Facebook’s Mark Zuckerberg (”I never take off the hoodie,” he’s bragged in interviews) but also favored by Twitter’s Biz Stone, Tumblr’s David Karp, and other next-gen moguls.
