Mischa Barton arrived at the British Academy Television Awards held at The Royal Festival Hall in London last April wearing a Osman Yousefzada Fall 2009 navy blue gown.

I fell in love with gold embellished turtle-neckline when I first saw this gown, so I wished at the time Mischa had worn her hair back to show off that detail to full effect.

The Prime Minister’s wife Sarah Brown has been front row at many shows this London Fashion Week, so she’s been taking in a lot of style tips.

At the 2010 Elle Style Awards last night she wore the same gown as Mischa Barton.

We thankfully got to see that stunning neckline with Sarah’s shorter hair, but unfortunately this picture is not doing her much justice as she looked much better in real life.

For taking a chance and experimenting with fashion and because everyone is bound to vote for Mischa, Sarah wins this for me.
