This study intends to analyze the up-cycling trend that is attracting great attention these days and its internal meaning in the context of fashion art. And, based on this, to provide enhanced value and creativity in the future fashion artwork and design businesses, keeping abreast of further fashion art developments. As part of the study methodology, both a literature review and a case study were carried out, along with an examination of up-cycling and research into related pictures and content. The materials covered in this work include design and fashion related books and domestic and foreign magazines from 2000 to 2011, when the up-cycling movement was initiated as a form of eco-friendly design. For the analysis of fashion art pieces, generic terms included art wear, wearable art wear, and unwearable art. Case review was followed by the works of artists shaping their fashion concept and meaning entirely from abandoned clothes and fabrics, waste materials, and their art collection. Consequently, key elements of the value of up-cycling fashion art are that it is eco-friendly, has a unique identity, and reflects multi-dimensionalism. This research saw the integration of fashion with other variables, artistic attributes, and reuse of resources. This could lead to a new realm where value-addition is formed and extended, thus providing another chance for the fashion industry.
