I've been a fan of Carey Mulligan since she starred in An Education, and I've been a fan of her style since she showed up to last year's Academy Awards in that Prada dress adorned with tiny metal forks, knives, and scissors. Seriously, that dress kind of blew my mind. She always chooses really fun and unexpected silhouettes, textures, prints, and colors. I love that she wears a lot of vintage-inspired styles, often with modern details (an architectural pleat here, an avant-garde print there). She always keeps it ladylike, but still interesting and youthful.
Also, Carey really reminds me of Edie Sedgwick with her blonde hair and dimples. She would've made a great on-screen Edie, don't you think?
