La Dolce Vita (1960)

Sylvia's black strapless gown in the Trevi Fountain, worn by Anita Ekberg The credit is disputed. The gown is often attributed to the Rome atelier of the Fontana sisters, while Piero Gherardi was the film's costume designer and won the Oscar for its costumes. Either way, its simplicity is why Ekberg wading into the fountain at night became the image of the film, front and center on its poster: one dark, uncluttered shape against pale water and stone. The film helped put Italian fashion on the world map, and this is the dress that makes the case.
