With a theme of 'Manus x Machine' we expected at least one light up gown on the Met Gala red carpet. And Zac Posen didn't disappoint.
The New York designer turned Claire Danes into a real-life Cinderella in an epic pale blue gown that emitted an ethereal glow in darkness.
Posen teased the beautiful dress in the hours leading up to the event, with many thinking it was his Project Runway colleague Heidi Klum who would be wearing the dress.
A series of Instagram posts showed the gown illuminating in all its sparkly glory before Danes was revealed as the wearer when she stepped onto the red carpet.
In one of the video clips Danes can be heard saying 'I won't be drinking tequila shots in this, let's just say that', before adding 'well, that's what I say now.'
