Gigi (1958)

Gaston (Jordan), the scion of a wealthy Parisian family finds emotional refuge from the superficial lifestyle of upper class Parisian 1900s society with the former mistress (Gingold) of his uncle (Chevalier) and her outgoing, tomboy granddaughter, Gigi (Caron). When Gaston becomes aware that Gigi has matured into a woman, her grandmother and aunt (Jeans), who have educated Gigi to be a wealthy man's mistress, enjoin on him to become her provider and on her to accept such a golden opportunity.
