Sustainable Fashion Product Innovation: Continuous Value of Apparel Products on Second-Hand Product Trading Platforms

Abstract

This study aimed to determine the appropriate fashion design elements for fashion product innovation to achieve continuous product value and promote sustainable fashion. We focused on five fashion design elements: classical, transformative, patterned, multimaterial, and decorative. Using an apparel auction market dataset, we verified how the five design elements contributed to the value continuation of apparel products across five categories. We statistically confirmed the design elements that positively affect the continuous value of different apparel products per fashion product categories. This study can help designers select elements that sustain product value, providing them with direct references for recommendations.
