Blood and Black Lace

This delirious mix of sex, sadism and style has a masked man stalking the gorgeous mannequins of a Roman high fashion house, murdering them in a strikingly fetishist manner and then leaving the corpses to be discovered like grisly works of art. Mario Bava's 1964 film, originally titled Sei donne per l'assassino, is one of the earliest slasher movies, and remains a suspenseful, disturbing and oddly seductive film.
