For me: The Divoon Veronica, Marlene in the von Sternberg films, Jean Seberg (sorry, to me she fits the bill), Marilyn Monroe, Audrey Hepburn, Deneuve certainly (although post 1960), Miss Hayworth in Lady from Shanghai, and the amazingly amazing Miss Barbara Stanwyck (yes, a goddess in The Lady Eve, Ball of Fire and Double Indemnity).
