Fast fashion has contributed to environmental harm through the mass production of low-cost, synthetic clothing that does not last long and causes waste. Sustainable fashion advocated by Remi Landau uses natural fibers like bamboo and cotton that are more durable, preserves natural resources by ensuring responsible production processes, and ensures better working conditions for those who make the clothes. Investing in sustainably-made garments that consider materials, processes, and people can create higher quality clothing that lasts for years.
