The study aims to suggest new skirt designs through a modernistic application of the silhouette of Hanbok skirts. It also aims to promote the aesthetic beauty and excellence of Hanbok to the world by using Hanbok skirts that best express the beauty of Korea as motifs, and to promote a pride in Korean culture through a reinterpretation of Hanbok skirts. The study was focused on examining Hanbok skirts from the Three Kingdoms era to the Joseon Dynasty, and the skirts in each era were compared to western silhouettes to suggest design centering on the characteristics of each silhouette. As for the theoretical background, shapes were classified according to waist-grip, the width and length of a skirt, wrinkles and ornamental lines, before being compared to skirt silhouettes of western costume. As a result, it was found that Hanbok skirt silhouettes in the Three Kingdoms era were similar to the A-Line silhouette of western costume, the Empire silhouette of unified Silla, the H-Line silhouette of the Goryeo Dynasty, the Bell-Line silhouette of the Joseon Dynasty and the Bustle Style applied to ceremonial costume in the early Joseon Dynasty. The researcher suggested five skirt designs by applying the above-mentioned five silhouettes, confirming the research premise that Hanbok skirt silhouettes are as diversified as those found in western costume. Designs were suggested for each silhouette, and are expected to lead to the development of designs befitting future trends and concepts through detailed research and development on Hanbok skirt silhouettes.
