Sienna Miller Has Debuted A Dramatic New Look

Although she frequently experiments with cuts and styles, Sienna Miller has always been a trademark blonde.  That's why we were so surprised when she stepped out this week rocking a very different look. Sienna attended the launch of her sister's Debenham's collection.  The boho-style-queen debuted a gorgeous cropped auburn look when she attended the launch of her sister Savannah's new collection for Debenhams. Teaming the look with a plain oversized grey jumper and black skinnies, the star was almost unrecognisable. Sienna is currently filming The Lost City Of Z in Northern Ireland.  The makeover might be short-lived however, as reports are surfacing that the look is for her character in The Lost City of Z, which is currently filming in Northern Ireland and also stars Brad Pitt and Robert Pattinson.
