From the silver screens of the 1940s to the gilded runways of this February's Fall/Winter Fashion Week, the sultry sirens of Film Noir seem to have cast their smoldering glare on the fashion world. Blurring the lines between feminine sophisticate and vampish rogue, classic noir heroines and their modern incarnations on the runway employ an empowered sense of style that's—luckily for us—just coming back into season. So heat up your fall wardrobe with all the mystery and allure of a fierce femme fatale—and don't forget the red lipstick.
