Recently, young people wearing hanbok are highly visible in the palace and in Hanok Village. However, there is much controversy regarding whether the hanbok the young people are wearing is traditional. Young people in Korea are exposed to hanbok through a variety of ways such as school education, games, webtoons, television shows, and movies. In this study, we presented teenagers with illustrations of hanbok to see which they preferred and which if any they recognized as traditional. The study respondents most preferred the hanbok from the 18th century, but they considered the hanbok from the 20th century to be the traditional style. We next used text mining to analyze the students’ freely written, open-ended responses regarding the hanbok they preferred and the one they considered traditional. The hanbok from the 18th century, the one the teenagers preferred, was a sexy, cool style related to gisaeng that emphasized the waist, whereas the hanbok they believed was traditional, the 20th-century hanbok, was simple, neat, comfortable, and plain. Among the young people’s responses regarding which hanbok was traditional, the text mining extracted the following repeated words related to both the 18th- and 20th-century hanbok: “dramas,” “mass media,” “historical dramas,” and “movies.” For the 18th-century hanbok only, we extracted “webtoons” and “Hanok Village,” and for only the 20th-century hanbok, we extracted “textbooks.”
