Helena Bonham Carter is known for her whimsical style, but last night at a London photocall, she knocked the sexy librarian look right out of the park. Even if you don't wear real glasses, you can get the look with fakies like these BCBGeneration Plastic Koi Glasses ($25). Cute little bows like these Grosgrain Bow Hair Clips ($1) are cheap and easy to come by, and for her lip look, you can use a mauve liner like Clinique Defining Liner for Lips in Plush Pink ($14) under a creamy light pink lipstick like Pur Minerals Lipstick in Pink Isocite ($16). Finish it off with pink blush across the apples of your cheeks, and you've got the perfect hot, smart look. To get more info on any of the products above, just click on the images.
