The global fashion industry is transforming as consumers increasingly prioritize sustainability, ethical practices, and environmental responsibility. According to SNS Insider Research, the sustainable apparel market, valued at USD 11.20 billion in 2023, is projected to grow at a CAGR of 9.1%, reaching USD 24.53 billion by 2032. In July 2024, the World Economic Forum highlighted the growing importance of secondhand clothing as a key element of sustainable fashion, particularly in the U.S., where thrift shopping is on the rise.
Similarly, countries like Australia have reaffirmed their commitment to sustainable fashion on the global stage. Organic cotton, which currently holds over 35% of the market share in organic clothing, is becoming mainstream as awareness of organic farming and the harmful effects of pesticides grows. Pioneering brands like Patagonia have set industry benchmarks by aggressively promoting organic cotton and fair-trade practices, driving demand for sustainable materials.
