The New Look is a women's fashion movement that began in post-WWII France, first introduced by Christian Dior in 1947 at his spring collection ( ligne corolle ) showing at 30 Avenue Montaigne in Paris. Dior's designs radically changed the feminine silhouette. The term was coined by Carmel Snow, the lead editor of Harper's Bazaar.

This phrase gained global recognition after an article by a Rutgers University journalist was published in the United States. Dior's first collection helped revitalize the French fashion industry following World War II. Europe was still suffering the consequences of the war at the time, but the New Look helped bring back opulence to the streets of Paris in the 1950s and restabilished it as an international centre of fashion. Haute-Couture had declined during the war.

The "New Look" emerged in the specific context of post-World War II Europe. Following years of wartime rationing and austerity , Dior's designs were radically different. The full skirts, made with extravagant amounts of fabric, defied the limitations and somber mood of the war years. The cinched waists and rounded shoulders emphasized femininity, a departure from the more masculine styles adopted by women during the war.

Christian Dior, born in Normandy in 1905, launched his first collection in February 1947 at the age of 42. His early career included running an art gallery with Jacques Bonjean, where they exhibited works by artists like Pablo Picasso, Henri Matisse, and Salvador Dalí. This experience exposed Dior to diverse artistic movements and aesthetics that would later influence his fashion designs.

Dior's entry into fashion design was gradual. He began selling sketches in 1935 and later worked for designers Robert Piguet and Lucien Lelong.  These positions provided valuable experience and connections within the industry.  In 1946, with financial support from textile manufacturer Marcel Boussac, Dior founded his own couture house.

Dior's designs were not only a reaction to wartime austerity but also a reinterpretation of historical fashion trends. The New Look's silhouette drew inspiration from the Belle Époque era and Victorian styles, which demonstrated Dior's ability to modernize classic elements.

The New Look redefined the feminine silhouette with dresses featuring a cinched waist and full skirt falling to mid-calf length; some skirts used over 10 meters of fabric. Christian Dior's "Bar Suit" transformed the traditional suit jacket into a feminine garment with rounded shoulders and a small waist. This design contrasted with the rigid, heavy military uniforms and utilitarian clothing worn by women during World War II, many of whom had to take men's jobs as they were displaced.

Key characteristics include:

The New Look was not universally embraced at the time. Some criticized its extravagance and impracticality, particularly in a time of continued economic recovery in Europe. In a time of post-war shortages, the extravagant use of fabric in designs was seen as excessive and insensitive by some. Some women had embraced more masculine and utilitarian styles, taking on new works traditionally associated with men during the war. The New Look's hyperfemininity could be interpreted as a rejection of this independence and a pressure to return to pre-war ideals of womanhood.
