My favourite movies of her are Pandora and the flying Dutchman, Mogambo, The barefoot contessa, The killers and Bhowani jonction.
Among the beautiful clothes she wore in her movies, i like especially the black asymetric gown in « The Killers » (designed by Vera West) and the gowns created for « The barefoot Contessa » (designed by the Sorelle Fontana).
To my mind, Ava Gardner was the most beautiful woman in the world.
