Sustainable Fashion Principle-Based Multifunctional Clothing

The rapid growth of the fashion industry has intensified environmental pressures, including excessive textile waste, high resource consumption, and increasing carbon emissions. In response, sustainable fashion has emerged as an approach that emphasizes efficiency, long-lasting use, and reduced environmental impact. This study examines multifunctional clothing design as an environmentally responsible strategy aligned with the Sustainable Development Goals (SDG 12), particularly responsible consumption and production. Multifunctional clothing enables users to wear a single garment in multiple contexts, thereby reducing clothing accumulation, minimizing textile waste, and extending product lifespan. Using a quantitative evaluative method, four multifunctional blouse designs were assessed by expert panelists against product quality and sustainability indicators. Results show consistently high scores across all sub-indicators, indicating that multifunctional clothing effectively integrates functional adaptability, aesthetic value, and sustainability principles. This research strengthens the argument that multifunctional design contributes to environmental conservation efforts, promotes resource efficiency, and supports the transition toward circular fashion systems.
