Bok-gil Jang (1624-1685) was a military officer in the Joseon Dynasty. His grave was located at Yeonhwa-ri, Jicheon-myeon, Chilgok-gun, Gyeongsangbuk-do. It was a grave in the Joseon Dynasty, excavated by Daedong Cultural Heritage Institute in 2008. From the grave, 45 artifacts including a mummy and costumes were excavated. Of them, 4 Jeogoris and 1 Jang-ot were excavated as women’s costume, while two Cheolliks, 4 Jungchimaks, and 1 Sochangui were excavated as men’s costume. All of the 4 Jeogoris are quilting style, and the difference between jindong and sugu is longer than 10 cm, which shows the diagonal slope of baerae is great. A Cheollik was made in one layer, and the other was made of detachable sleeve. The colors of Jeogori (or eui) and skirt (or sang) of the Cheollik (artifact number 666) are conspicuously different. This Cheollik is a very important artifact in that other Cheolliks that have been found so far were all made in one color. Of the 4 Jungchimaks, 3 Jungchimaks’ sleeves are detachable, which shows only Jungchimaks for military officers had detachable sleeves. This study identifies that the costumes excavated from the Jang Bok-gil grave had the characteristics that are found from those in the 17th century.
