Claire Danes has given new meaning to lighting up the red carpet.
The 37-year-old actress looked like a fairy tale princess in a voluminous white dress at the Met Gala in New York on Monday night.
But she stunned everyone when the lights went off and her kwaai dress lit up like a firefly.
The pale blue strapless frock, designed by Zac Posen, had a heavy 30 pack battery sewn into it to supply power for the liggies.
The dress was spot on for this year’s futuristic theme, titled: “Manys x Machina: Fashion in an Age of Technology”.
A proud Posen tweeted: “The stunning #ClaireDanes in my custom made Fiber Optic Woven Organza Gown @metmuseum #MetGala2016 (sic)”
Before the Met, he teased mense on social media by showing pictures of his dress, without revealing who was going to wear it.
Claire attended the event with her hubby Hugh Dancy, who didn’t even try to compete for the spotlight.
But Claire wasn’t the only one who took the futuristic theme to new lights.
Model Karolina Kurková relied on social media to light up the flowers on her rok.
Designed by IBM Watson Technology, the blommetjies lit up in response to comments on Twitter and Instagram.
Tiny LED lights embedded inside the fabric responded to five emoticons linked to The Met Gala hashtag – joy, passion, excitement, encouragement and curiosity.
When the dress detected those emotions, the flowers changed colour.
