Known for setting a trend or three, Sienna Miller is sure to cause a stampede to the hairdresser's with her new look.
Stepping out with fashion designer and BF Matthew Williamson at his Belvedere party last week, Sienna showed off her new heavy fringe and choppy layers.
We have to say, it's her best look yet.
Actress and fashion designer Sienna has tried many a hairstyle over the years – from loose boho waves to a choppy bob – as well as a short, gamine crop for her part as Edie Sedgwick in Factory Girl.
Time to go for the chop? We think so... a fringe is the quickest way to update mid-length and long hair – and instantly take off years.
