Vanity Fair has unleashed its list of Silicon Valley's most stylish dressers, and boy are there some surprises. 

Apparently Netscape founder Mark Andreesen is just as fashion forward as Yahoo CEO Marissa Mayer, while Sean Parker, he of Napster and Social Network fame, cuts as lean a figure in a suit as Mashable founder and CEO Pete Cashmore. (We're assuming hoodie enthusiast and Facebook wunderkid Mark Zuckerberg was left off the list for this reason.) 

Whatever your views of West Coast culture might be, you're sure to get a kick out of the slideshow, which reads like a who's who of the tech world's heavyweights.
