In my opinion, the responsibility of a fashion designer is to help society solve problems or lead consumers' fashion concepts through the medium of clothing. Sustainable fashion has become the hottest fashion topic today, and how to achieve the purpose of environmental protection through the sustainability of clothing has become the topic of designers. When I learned that polyester fabric ranked second in the world's environmental pollution category, I developed a strong interest in sustainable fabrics and clothing, including bio-plant fabrics, zero waste fabric, second-hand clothing reuse and so on. I started doing a lot of experiments to support and enrich my fashion project. Techniques such as Blender, 3dclo, and plant dyeing are very helpful to my project.
