Hanbok (South Korea) or Joseon-oth (North Korea) is the representative example of traditional Korean dress. It is characterized by vibrant colors and simple lines without pockets. Although the term literally means “Korean clothing”, hanbok usually refers specifically to clothing of the Joseon period and is worn as semi-formal or formal wear during traditional festivals and celebrations. Korea had a dual clothing tradition in which rulers and aristocrats adopted different kinds of mixed foreign-influenced indigenous styles while commoners preserved a distinct style of indigenous clothing, today known as hanbok.
