It may not be everyone's taste, but you have to give Mark Zuckerberg credit for his commitment to the T-shirt and hoodie aesthetic.

The Facebook founder doesn't often stray from his signature style, but on Monday gave us all a peek at how basic his wardrobe really is. After a two-month paternity leave, Zuckerberg — naturally — wondered what to wear for his first day back in the office this week. So he posted a photo of his options and asked his Facebook friends for their opinions.

"First day back after paternity leave," he wrote. "What should I wear?

The photo features nine identical gray T-Shirts and seven slightly darker gray hoodies, hanging neatly on what looksl like velvet no-slip hangers. The T-Shirts even appear to be ironed, with creases on the sides of the sleeves.

Zuckerberg has addressed his basic sartorial preference in the past. Allowing himself one less daily concern — picking the right tie to match a suit coat — means he has more energy to dedicate to running Facebook, he said in a 2014 Q&A.

"Even though it sounds silly that that's my reason for wearing a gray T-shirt every day, it's true," he said. "Steve Jobs did it."

His casual threads haven't always sat well in the business world, however. Back in 2012, Zuckerberg hit to road to woo investors ahead of the company's initial public offering, and his hoodie raised some eyebrows amongst the button-down set on Wall Street. At the time, Wedbush Securities analyst Michael Pachter called Zuckerberg's attire a "mark of immaturity."
