This year's Met Gala wasn't short of talking points, but the undisputed star of the event was Claire Danes and her fairytale light up dress by Zac Posen.
Made with fibre optic woven organza, the Cinderella-like dress lit up on command, literally brightening up the red carpet.
Bridal dresses usually play with length and silhouette, adding a 3D flower here and there, but the Met Gala was all about wearable technology.
Taking its theme from the Met Ball's new exhibition, Manus x Machina: Fashion in an age of technology, designers created truly futuristic custom pieces.
But Posen's design wasn't the only piece that sparked interest, Karolina Kurkova's flower adorned Marchesa dress put the control into the world of social media. Reactions on twitter changed the colour of the 150 LED lights to reflect the tone of each tweet - think aqua for excited and rose pink for joy.
Would you wear a light-up dress on your wedding day?
