Americans seem to have no time to settle down and do fine arts. Although I like big scenes, it is a bit rough, and I can't see much historical and cultural traditions from the costumes. However, because it is very modern, it attracts young people all over the world with a relaxed and casual style. Simple modern ready-made clothes are based on the American way of life. Therefore, all "informal" clothes in the United States seem to be designed as loose and comfortable as pajamas. Taking military uniforms as an example, the Soviet-style waist is long and looks tall; British soldiers are as strict as gentlemen; German military uniforms show majesty and discipline; American military uniforms are fat and casual, revealing the American lifestyle. First, they pay attention to efficiency, luck and comfort, and second, they pay more attention to the overall clothing elements in Europe.
