Can Sienna Miller do no wrong? This week the blonde model, actress, and style aficionado showed off her lithe limbs (and love of nature) in a short and sweet summer dress. The floral print style, which featured a flattering sweetheart neckline and prom-style skirt made the most of Sienna's curves whilst showing off her runway-worthy proportions. Known for being a bit of a 'green queen' Sienna was the perfect choice to launch new electric car, the BMW i3, in London but it was hard to take an interest in the car when Sienna was sporting one of SS13's hottest looks! We're guessing Sienna's floral frock is a little out of our price range but lovely vintage-inspired dress brand, Louche have the purse-friendly answer to stealing her summer style. The Lurah dress (£69) is the perfect piece to channel Sienna's look and won't break the bank. And teamed with lattice-effect strappy wedges from Bourne (£111.30) and statement earrings (£30), you've got the perfect boho-chic, day-to-night style. Shop the look: Louche Lurah Dress in Floral Print, £69; Bourne Chrissy Shoe, Was £159, Now £111.30); Fiorelli Pink and Orange Resin Earrings, £30; Fiorelli Sunburst Ring, £19.95.
