I was lucky enough to visit a hanbok shop in Insadong on the day of their Fall Cultural Festival. They had drawings for prizes and trips to temples, traditional crafts and a parade celebrating the clothing styles from the Three Kingdoms era. It was really interesting, not only to try on my own hanbok, but also to see the many different styles from the past. Insadong is a popular tourist area, so they hold the festival to teach people more about the history of Korea, including clothing, arts and crafts.
South Korea has many significant cultural sites, not just in Seoul, but around the country. They take care to preserve them while keeping many open to the public to educate them about their history. At many of the palaces and other sites, they have Hanbok Tours that allow people to dress up in traditional hanbok while they explore the area. I think this really shows how much South Korea is determined to stay connected to their history and educate both Koreans and foreigners about where they came from and how that still influences their culture today.
