Galadriel looks: Cate Blanchett leads the glamour as she walks the green carpet at the UK premiere of The Hobbit: An Unexpected Journey on Wednesday night
She wowed the crowds as she stepped on to the green carpet in a stylish floorlength winter white Givenchy gown, ensuring she was wrapped up more for the London winter than she was for New Zealand's summer at the original November premiere.
Cate, 43, did, however, vamp up her look with a backless cut out detailing showing off some flesh to the excitable crowd.
The actress, who plays Galadriel in the Middle Earth drama, finished off her look with her blonde locks in a simple up 'do, while carrying a cute clutch bag.

The Hobbit actor, 73, admitted he hasn't had any treatment for the disease, but is examined regularly and it is 'contained'.
He admitted he originally feared the worse when doctors first told him he had the disease, but his concerns were soon allayed.

A whole host of other stars gathered in the West End for the royal UK premiere of the new Hobbit film.

Andy Serkis, who also reprises his role from the Lord of the Rings trilogy, and Office star Martin Freeman, who plays main character Bilbo Baggins in the JRR Tolkien adaptation, all attended.
They were joined by showbiz figures including boyband McFly, who braved freezing temperatures on the green carpet in front of hundreds of screaming fans.

He added: 'Its cast is basically British and from the Commonwealth, Tolkien was an English writer, here we are in the capital city and it feels proper.'
Australian actress Blanchett, who plays elf queen Galadriel, joked about the cold.
'The weather is enough to drive anyone away but it is great to see so many fans,' she said.
She wore a stunning white backless dress but had donned a black jacket by the time she went into the cinema for the performance.
Olympic long jump gold medallist Greg Rutherford was among the celebrities attending, along with singer Nick Cave.
During the evening lead star Freeman admitted it was a challenge to star as The Hobbit himself, and he hoped fans enjoyed the film.
'I loved playing it. I really loved playing it. I hope people like it. There's nothing more you can do. It's in the hands of Peter Jackson and the editors.'
But he admitted that travelling between New Zealand and his home in the UK, where he lives with his young family, had been the greatest challenge.
'That was probably the major test - the mental and emotional test of actually leaving your home for that long.
'But the gig itself was a real pleasure and a challenge in all the best ways.
'Sometimes they're hard challenges, but sometimes they're fun. It was an amazing job, I'll never do another one like it.'
Serkis confessed he had not had chance to miss his role as Gollum in the time since he made the Lord Of The Rings trilogy because he is still often asked to do the voice.
He joked: 'I never thought he was ever going to go away. He's never really drifted very far from me.
'But it was lovely to play the scene with Martin, it was day one of 276 days of shooting.'
Serkis only makes a small appearance in The Hobbit but ended up staying on to work behind the camera.
He said: 'My unexpected journey on this was thinking I was going Down Under to reprise the role of Gollum for two weeks and then Peter asked me to direct the second unit, so I ended up going for a year and a half.'
