Hanbok or Joseon-ot is the representative example of traditional Korean dress. It is characterised by vibrant colours and simple lines without pockets. Wikipedia
During my holiday trip to South Korea. I have seen many tourists rent out Hanbok for their holiday photograph in Korea. Seems like very popular and easy to rent out per hour. I was enjoyed to just looking at people wearing them but for me almost spent money with food!.... Yes, Korean food is great.
