The growing emphasis on sustainable development across industries has prompted the fashion sector to explore responsible and resource-efficient practices. Applying this theoretical framework to the development of original fashion works, this study investigates the relationship between Korean aesthetic consciousness and sustainable fashion design. The research proceeds in three stages. First, a literature review was conducted to analyze the aesthetic characteristics of Korean aesthetic consciousness, categorized as aesthetic naturalism, elegant simplicity, and aesthetic humor, and to examine how these characteristics relate theoretically to sustainable fashion design principles, such as cyclicity, ornamentation, and deconstructivity. Second, based on this analysis, key design attributes were derived and used to develop six sustainable fashion works using the theme of Haya (夏夜, summer night), with motifs drawn from the Cheonghwa Baekja, a cicada, and pearls. Third, digital prototyping was carried out using the CLO 3D program, and final garments were produced with secondhand items, deadstock materials, and textile waste. The results demonstrate that upcycled materials can yield aesthetically sophisticated and functional garments. They also show that Korean aesthetic values provide a culturally grounded framework for sustainable fashion practice. The use of 3D CLO effectively reduced carbon emissions associated with physical sampling and enabled the verification of resource usage. This study proposes a creative method for integrating Korean aesthetics into sustainable fashion design and provides practical directions for future sustainable fashion development.
