On the red carpet: Firth, Watts, Stewart, Blunt

Yet again Colin Firth looks the dashing gent on the red carpet.

And he’s bang on trend too. Just this week The Guardian’s fashion writer Hadley freeman declared the tie to be a “tired '80s anachronism”.

Naomi Watts arrived at the premiere of her new movie The Impossible in Toronto in a stunning lilac Ellie Saab gown. It’s figure-hugging and low cut, yet somehow still looks classy and demure.

It was her first appearance post-RPatz scandal. Kristen Stewart knew the world would be watching — and she never looked better when she stepped out in killer heels, sleek ponytail and a Zuhair Murad dress.

Emily Blunt went green at the premiere of Arthur Newman. Supporting Livia Firth’s Green Carpet Challenge, she wore a Tory Burch eco-friendly gown and recycled brass necklace.
