Sienna Miller left her bohemian side behind and slipped into a feminine floral Dolce & Gabbana dress ($1,495) for the BMW i3 global reveal in London last night. The statement dress featured fresh hues, a sexy corset bodice, and a ladylike flared skirt — the perfect retro trifecta. Sienna then added chandelier earrings and black ankle-strap sandals to round out the ladylike look.
