Copy Sienna Miller's Wardrobe

Far from the days of the 'Sienna Miller bohemian fashion revolution', the svelte Hollywood pin-up is now a bonafide fashion designer (she co-owns Twenty8Twelve with her sister Savannah) and red carpet starlet; sporting plenty of her fbf's (fashionable best friend), Matthew Williamson's range. Moreover, she has managed to re-vamp her overly copied look from yonder years.   Her style has evolved from hippy-chic outfits and embellished belts to sleek, sophisticated cocktail dresses and neutral jersey casuals. Sienna remains in our style subconscious because fashionistas can relate to her two fashion modes; on-duty-fabulous and off-duty-but-still-fabulous. Which other star makes grey leggings, a tatty T-shirt and Vivienne Westwood boots understatedly chic AND opts for AllSaints dresses while other celebs squeeze themselves into predictable Herve Leger body-cons? None other than Ms Miller. We crown her queen of casual cool.
