Why hello! Sienna Miller looked ridiculously smokin’ throughout London Fashion Week but it was this outfit she wore to the Matthew Williamson show that placed her firmly back on the girls-whose-style-we-want-to-steal list. Understated and cool, it’s a genius mix of tasty jewel colours and tactile textures that works in a daytime situation or – thanks to the wow fur stole revving up the glam levels – nighttime too.
