The rise of the "small order, quick response" model in the fast fashion industry is driven by the increasing trend of fragmented demand for clothing orders. This requires collaboration between clothing brands and factories to meet the needs of personalized and diverse products. This trend also poses new demands on the collaborative mechanisms and production processes of factories, as well as the stability and variety of materials suppliers. SHEIN's success in implementing this model has led to a significant increase in its sales, and has also changed the traditional relationship between clothing brands and factories. Despite the rise of sustainable fashion and brands like Uniqlo shifting focus away from fast fashion, the market demand for "small order, quick response" remains the core demand in the clothing industry. With the Chinese clothing market being estimated at nearly 2 trillion yuan, the fragmented and independent nature of the industry's supply chain, along with consumer demand for customization and cost-effectiveness, further contributes to the market's need for the "small order, quick response" model.
