Jennifer Lopez — The Green Versace (2000 Grammys)

J.Lo's plunging green Versace dress at the 2000 Grammys generated so many Google searches that the company had to invent Google Images — literally. Before that dress, Google returned text results only. Eric Schmidt confirmed this origin story. The dress was designed by Donatella Versace with a neckline that descended to the navel. It was the first time a single outfit changed the internet's infrastructure. J.Lo re-wore a version at the Versace 2020 runway show, and it went viral again. One dress that changed technology, fashion, and pop culture simultaneously. There's no competition.
