Leave it to Sienna Miller to give the ever-trendy bob an extra edge! Over the weekend, the star was spotted out in London with a graphic asymmetrical cut, which walked the line between a chin-skimming bob and a collarbone-length lob.When it comes to trying out (or starting) the next big trend in hair, Miller has no qualms over changing up her own 'do. She's been a platinum blonde, deep brunette, and just about every shade in between--including pastel pink--and has even chopped her long layers into a pixie to play Edie Sedgwick in Factory Girl. "I'm really not too attached to my hair," she told InStyle previously. "If I worried about what people thought about my look, I'd get it all wrong."
