It isn’t often we get the opportunity to peer inside a billionaire’s wardrobe, so when Mark Zuckerberg posted a photograph of his online yesterday, the world scrutinised deeply. Will there be bespoke, fat cat-style pinstripe suits, we wondered? A row of Rolex watches? Shoes with goldfish contained in the heels?

There was not.

The Facebook co-founder revealed a limited clothing collection via an update – on Facebook, obviously – in which he joked about facing a tricky sartorial choice upon his first day back in the office after paternity leave.

Rather than any ostentatious designer workwear, Zuckerberg’s wardrobe featured just a row of grey t-shirts and grey zip-up hoodies. The morning routine of a entrepreneurial genius, it seems, is to save the unnecessary time spent deciding over changing outfits each day.

To keen observers of Silicon Valley fashion trends, Zuckerberg’s choice of t-shirts and hoodies is no revelation. The 31-year-old has rarely been seen in anything else, it being the unofficial uniform of tech start-ups. Removing all semblance of colour variation, however, is a bold new step.

But is it a genius move, or one of a psychopath? Naturally, the online community, who are after all Zuckerberg’s people, aired urgent opinions.

Taking a curious financial hack angle, Lou DiMaggio suggested Zuckerberg’s saving on different coloured t-shirts could be responsible for his enormous personal wealth. We presume it’s more likely to do with the social media website Facebook.com, but it’s certainly an argument worth hearing.

Others, like Aiden Arrendondo, seemed largely lost for words:

Jessie Lim gave a backhanded compliment, after pointing out that Daniel Radcliffe also wore the same t-shirt for an extended period of time.

Shakespeare probably didn’t foresee the Silicon Valley generation when he wrote that “Clothes make the man”, but it has since been argued that successful people wear the same thing every day. And Zuckerberg, whose net worth exceeds $46 billion, is certainly successful.

So where do you stand? Sartorial genius, or robotic psychopath?
