If, while watching The Social Network, you were either not horrified by or--shudder--gave a thumbs up to Mark Zuckerberg's shower sandals style, this article is for you. (If you wore shower sandals to the movie theater, this article is really for you.)

Flipping through back issues of Entrepreneur, we noticed that budding business moguls consistently make some prominent fashion faux pas.
