Sarah Brown wears most daring dress yet at awards bash as Dannii triumphs

Since stepping into the limelight two years ago, Sarah Brown has refined her own elegant sense of style.

And after a series of demure outfits, the prime minister's wife is clearly keen to try something a bit more daring.

Stepping out at a magazine awards in London this week, Sarah was the talk of the ceremony in a revealing silk dress.

She paired the low-cut, olive green chiffon-over-silk gown by British designer Catherine Deane with a pair of LK Bennett shoes.

Finishing off the look was a gold cuff from London gift shop Oliver Bonas.

Sarah was on a panel of judges at the event, which honoured inspirational women. Another judge - X Factor's Danni Minogue was one of the night's big winners, taking home a gong for top TV personality of the year.

Other winners included pop newcomer Pixie Lott, and Girls Aloud band member Kimberley Walsh.

The singer - elegant in a white halter neck gown - was congratulated by Melanie Brown on being named 'Woman's Woman'.
