In 1940, the shortage of materials during World War II had a direct impact on the garment industry. It has also affected the women's skirt length. In the year of limited supply in the clothing needs, of course, the style is short and small. The the number of tuck sleeves, belt and width have corresponding provisions. The skirt is to the knee’s length and cutting narrow. Practical strong suit is prevailing. Until 1947, in the post-war recovery of haute couture in Paris, people eager to re-wear pretty clothes, Dior introduced a "NEW LOOK" skirt: it is long to legs; skirt’s hem is large, with rounded shoulder; it is full of beautiful of women’s body. In addition, perhaps because of the World War II’s mini skirt, more slender and narrow pencil thin skirts have become popular.
