From 1945 to 1970, the development of French clothing can be roughly divided into two stages: the first stage is from 1947 to 1957, which is the so-called "Dior era", which began with the so-called "new style" fashion designed by ChristianDior. The second stage is the turbulent era in the history of clothing. Around the youth cultural movement, clothing appeared a series of popular phenomena, and began to develop towards the trend of youthfulness and asexuality.

During the period of 1947, Dior launched the first revolutionary "Corolla" series designed by him in Paris, which was a blockbuster. This kind of fashion, called "new style", has a unique female curve shape, which has changed the depressed and gloomy mood of European clothing. Later, he introduced the airfoil, the vertical line in 1950, the ellipse in 195 1, the wave curve and shadow in 1952, and the shadow in 1953. Every Dior fashion collection has become an authority on fashion, and new styles are often produced by American clothing manufacturers a few weeks after being exhibited in Paris, and quickly put into the market through wholesalers and retailers at all levels. The most outstanding thing about Dior's design method is that he has been trying to grasp the overall image of clothing design from the external modeling line, and treat the clothing modeling as a three-dimensional space modeling that can be continuously molded.
