This study examines the historical background, types, and characteristics of apron-style clothing from the Joseon dynasty and reinterprets them through contemporary fashion design. Here, apron-style clothing refers to clothing worn over a first layer, secured with straps, and structured to cover the front of the body. During the Joseon dynasty, apron-style clothing was differentiated according to purpose as follows: daily use, performance use, and ceremonial use. Structurally, it can be classified into four types: square, square with multiple straps, three-pronged with waist gathers, and three-pronged with narrow pleats. Based on Joseon-period apron-style clothing’s historical significance, structural features, and layered visual effects a total of four contemporary fashion designs were developed using CLO 3D as a design tool: Design 1 is a mini dress in a tube-top style derived from a simple square apron, Design 2 is a mini dress that reinterprets the Yuso [流蘇] decoration of the Boro [甫老], Design 3 is a cape design divided into three sections that is inspired by the Suboro [繡甫老], and Design 4 is a layered skirt reflecting the pleated structure of the Jeonhaeng-utchima [前香上裳]. The design outcomes demonstrate that the structural characteristics of traditional apron-style clothing are effectively expressed through silhouette, while their layered qualities are rendered with depth using different materials and colors. This research are expected to contribute to a deeper understanding of Korean traditional costume and to expand its value and potential for contemporary application.
