Dior's prom dress designs are more voluptuous than the boxy, fabric-conserving shapes of the recent World War II styles, influenced by the rations on fabric. He was a master at creating shapes and silhouettes; Dior is quoted as saying "I have designed flower women." His early look employed fabrics lined predominantly with percale, boned, bustier-style bodices, hip padding, wasp-waisted corsets and petticoats that made his prom dresses flare out from the waist, giving his models a very curvaceous form. The hem of the skirt was very flattering on the calves and ankles, creating a beautiful silhouette. 

Rest assured, you will never find yourself coming or going in a Dior prom dress!
