Dorsey is known for his bold sartorial choices in Silicon Valley, where the standard uniform for men, from engineers to CEOs, tends to be jeans and a hoodie. Dorsey has favored the work of the edgy menswear designer Rick Owens. He used to dye his hair bright colors back in his “punk” days, and he has worn unusual open-toed sandals to speaking events. He also recently revived his habit of wearing a nose ring, which was on display today, along with a beard, on Capitol Hill.

Whether it was his rather frank remarks to the committee, or his choice of collar styling, Wall Street seemed unimpressed by Dorsey’s appearance today. At the time of publishing, Twitter’s stock price had fallen more than 5%, to about $33, from today’s opening price.
