The purpose of this study was to propose up-cycling fashion designs, based on guidelines derived from up-cycling fashion brand products and their required elements of the design. The study thus categorized required elements into environment, significance, economy, function, design, and material, then extracted a set of design guidelines. The guidelines for waste resource-based up-cycling fashion design include the followings: First, authenticity, taking mutual environmental relations into account. Second, rarity of products beyond the domain of standardized ready-made goods thanks to manual operation. Third, storytelling, reflecting the consumer history. Fourth, sustainability to signify the circulation of matters. Fifth, experimental characteristic to fulfill creative innovation. Sixth, changeability through interactions with wearers. The investigator decided design concepts based on them and created up-cycling design works with waste plastic bags, shirts, stockings, neckties, outdoor mats, and backpacks in a variety of formative expressive techniques.
