Hanbok (South Korea) or Chosŏn-ot (North Korea) is the traditional Korean dress. It is often characterized by vibrant colors and simple lines without pockets. Although the term literally means "Korean clothing", hanbok today often refers specifically to hanbok of the Joseon (Chosŏn) period and is worn as semi-formal or formal wear during traditional festivals and celebrations.
Throughout history, Korea had a dual clothing tradition, in which rulers and aristocrats adopted different kinds of mixed foreign-influenced indigenous styles, while the commoners continued to use a distinct style of indigenous clothing that today is known as Hanbok.[1][2]
In 1996, Ministry of Culture and Tourism of Korea made 'Hanbok day' to encourage people to wear Hanbok.[3]
