Claire Danes Won The Theme At Tonight's Met Gala

Designer Zac Posen had us racking our brains when he teased photos on his Instagram earlier today of a stunning glow-in-the-dark Met Gala gown captioned with, "Guess who?"

Though commenters' first guesses were Heidi Klum—who, as we see every Halloween, is a pro at dress-up—the woman in question turned out to be Claire Danes. The actress stunned on the red carpet with a red lip and her hair pulled back in a sleek bun, channeling some serious Cinderella vibes with Posen on her arm. Winning the night's theme, Danes's look was the perfect hybrid of fashion and tech.

We were hoping they'd switch off the lights for a moment so we could see that dress in action. Watch the gown in action below:
