This research was designed to study the different kinds of ancient patterns applied to the Korean traditional suit and the symbolism associated with these patterns being used the prevalent Han-bok collections in markets. The shapes and changes in the use of the patterns can be summarized as follows. The published collections in the last 5 years were specifically concentrated between 1996 and 1997, proving that the development in Han-bok designs was most active during that time. But the trend decreased due to the effects of a depressed domestic economy. The plant pattern was the most utilized pattern for practical purposes. It looks beautiful and it is also easily manufactured with open space. Symmetrical and linear arrangements make customers feel stable at sight and these patterns tend to attract public gaze resulting in increased sales. There is a problem whether to continue using the existing patterns of the Han-bok without any correction or whether to copy the pattern of the kimono or the western suit. Copying other patterns definitely hurts the elegance of the Han-bok. It is time for us to not only keep our own traditions but also to study and develop new patterns that are distinct from the Chinese and Japanese patterns. The following are suggested as the basic materials.
