They came, they saw, they technologied.

Last night (May 2), Hollywood elite, media moguls and pop superstars mixed and mingled at the annual Met Gala, hosted at the Metropolitan Museum of Art. The night's theme, a celebration of the exhibit Manus x Machina: Fashion in an Age of Technology, lent itself to a whole range of tech-y interpretations — from the literal (Zayn's rObO-aRmOr!) to the, uh, more interpretive. (Selena Gomez?)

In any case, a ton of our favorite pop stars showed up in their finest costumes to join in on the celebration. But here's the question: who wore it best?

Take a look through the gallery above, which includes the gala's honorary co-chair Taylor Swift, a Game of Thrones-looking Madonna and Lady Gaga in full-on pop star mode like The Monster Ball Tour never ended.
