Marcel Boussac, a successful entrepreneur known as the richest man in France, invited Dior to design for Philippe et Gaston, a Paris fashion house launched in 1925.
Dior refused, wishing to make a fresh start under his own name rather than reviving an old brand.
On 8 December 1946, with Boussac's backing, Dior founded his fashion house. The actual name of the line of his first collection, presented on 12 February 1947, was Corolle (literally the botanical term corolla or circlet of flower petals in English), but the phrase New Look was coined for it by Carmel Snow, the editor-in-chief of Harper's Bazaar. Dior's designs were 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 look employed fabrics lined predominantly with percale, boned, bustier-style bodices, hip padding, wasp-waisted corsets and petticoats that made his dresses flare out from the waist, giving his models a very curvaceous form.
