Now, don't get me wrong Sienna always looks amazing, but at party last week she looked even better. Sporting a pop of bold lipstick (very ss '10) and a new fringe she proved that it's the little tweaks that can take your look from great to off-the-scale.

Sienna hadn't opted for anything drastic but her whole style was altered for an evening. The fringe was worn sleek for a change; but once her hair is disheveled and centre-parted, her hair will look just as it always did. Proving this to be a very versatile cut.

I tracked down Sienna's assistant, well I needed to find out who was behind this stroke of hair genius and book myself in pronto. Said assistant came back to me with this,

"She said that it wasn't any one person who did her hair, her friend cut it - who isn't a hair dresser - and then another touched up the fringe... And on the night of the Matthew Williamson party she did her hair herself, just up in a ponytail."

So Sienna, how's your diary fixed for a styling session this Saturday?
