Claire Danes' Met Gala dress

There was some serious style (and to my eyes, certain cases where there was a lack thereof) on the Met Gala red carpet last night. You can check out all the celebs here and tell us which dress you'd borrow to wear to Tesco to buy milk.

My favourite was Zoe Saldana, just pipping Katy Perry for her 'zero f**ks given' approach.

But it's Claire Danes who has the internet buzzing this morning because her look literally lit up the room last night.

Zac Posen posted some pics to Instagram as she got ready for the evening with the theme of "Manus X Machina: Fashion In An Age Of Technology".

So far, so Posen.

I love the soft blue shade and the back is deserving of a special mention.

And then, the flipping thing lit up.

She's like the strip lighting in case of emergency.

I'm sure Thelma Madine made one like this before. Zac, I know what tv shows you're watching and it ain't Homeland.
