He did suggest, though, that Zuckerberg should try to act more respectful to the people he hopes will fund his company.

"Some Wall Street types are muttering about Zuckerberg's attire being disrespectful and immature, and they could be right," he said.

"It could be taken as studied indifference, arrogance, or that he simply didn't think about what he was putting on. He was there to sell Facebook as a company and the first rule of sales is that you don't give your prospective customers any reason to be uncomfortable before you start selling them," Olds added.

Patrick Moorhead, an analyst with Moor Insights & Strategy, said that on the other hand, Zuckerberg could be getting the respect of other potential investors by not pandering to his audience.

"Zuckerberg is the 'mad scientist' of Facebook and the last thing anyone needs is him suiting up and faking it," Moorhead said. "Facebook wants to be all about being real, hip, young and cool. And suits just aren't. Zuckerberg's hoodie is about as famous as Steve Jobs's black turtleneck and blue jeans. It would be ill-advised to change for a financial roadshow."
