I started with my research by looking at Korean traditional clothing called Hanbok. Hanbok today often refers specifically to hanbok of Joseon Dynasty and is worn as semi-formal or formal wear during traditional festivals and celebrations. The modern hanbok does not exactly follow the actual style as worn in Joseon dynasty since it went through some major change during the 20th century for practical reasons.
Throught history, Korea had a dual clothing tradition, in which rulers and aristocrats adopted different kinds of mixed foreign-influence indigenous styles, while the commoners continued to use a distinct style of indigenous clothing that today is known as Hanbok.
Traditional women's hanbok consists of jeogori, a blouse shirt or a jacket and chima, a wrap-around skirt, which is usually worn full. The ensemble is often called chima jeogori. Men's hanbok consists of jeogori and baji which means pants in Korea. The baji were baggy pants in traditional men's hanbok.
