Each year, droves of tech founders, funders, and dreamers descend on TechCrunch Disrupt. And for years the event was regarded as a kind of fashion wasteland. Hoodies and ill-fitting jeans passed as the uniform onstage and at after parties. Back in 2015, GQ felt compelled to write an entire tribute to the "one well-dressed man" at the conference.

But as the curtains rose on the startup world's big tent at the Moscone Center in San Francisco last week, the  fashion transformation was undeniable. Well-heeled venture capitalists shed their puffy vests for tailored suits and cashmere, and stilettos were almost as commonplace as sneakers. Granted, the tech superstars onstage were the first ones kicking boring attire to the curb, flaunting elegant ensembles that might seem misplaced amidst the sea of understated logo tees in the audience.

See who brought the glitz and glamour, and who maybe should have stayed off the green carpet.
