Fashion has been affected by the change of periodic conditions. A good example is found in the relationship between fashion and periodic conditions before and after World War I in the U.S. During the pre-wartime, the artificial silhouette achieved through using devices like the corset was popular and then women's dresses were very decorative and gorgeous using a wide variety of details. S-curved silhouettes and Paul Poiret's style will be reviewed as distinctive shapes of pre-war fashion in the beginning of the 20th Century. Through the war, women's rights improved enormously, the use of the automobile increased tremendously, and various kind of sports, the movie industry and ready-to-wear market developed very much. Women's clothes also changed to be much more practical and functional in post-war fashion. It seems that fashion is affected by the change of periodic conditions.
