This week on the red carpet

Bradley Cooper shows the guys how the red carpet should be worked at the New York premiere of American Hustle.

The actor looks slick in a Vivienne Westwood coat and a Todd Snyder suit.

Mrs Colin Firth continues to fly the flag for sustainable fashion in this show-stopping, eco-friendly Paul Smith tux. Livia Giuggioli is well and truly winning her Green Carpet Challenge.

Could this really be Downton’s Anna Bates? Joanne Froggatt wears a stunning, strapless black jumpsuit at the British International Film Awards. But it’s the styling we love — sleek fringe and lashings of eye liner.

Skinny jeans aren’t going anywhere in 2014, but perhaps they should come with a warning label — not too tight, ladies. The stunning Roz Purcell is a case in point at the Anchorman 2 premiere.
