Mark Zuckerberg and the hoodie that sparked a controversy

How do you dress for success? For men, the standard in some quarters remains the suit and tie, especially in the heart of the business and finance worlds. But in Silicon Valley and other outposts of tech, casual is quite often the way to go. Sometimes, those worlds collide. Consider the kerfuffle unleashed this week when Mark Zuckerberg headed to Manhattan for Facebook's IPO road show.

It seems Zuck's dorm room fashion rubbed some folks on Wall Street the wrong way. The CEO of the universe's biggest social network caught flak for wearing his hoodie -- as integral to his public persona as the black turtleneck was to Steve Jobs' -- to a meeting in New York with potential Facebook investors in the company's upcoming IPO, likely to erupt late next week. One Michael Pachter, an analyst for Wedbush Securities harrumphed his disapproval, calling it a sign of Zuckerberg's lack of seriousness and a "mark of immaturity."
