In the current international online shopping fashion sector, three major trends dominate the consumer market: First, "scenario-based personalized customization" is on the rise. Over 70% of platforms have launched customization services for clothing and footwear, allowing users to select fabrics, modify styles, and even add exclusive embroidery online. The number of customized orders has increased by 58% year-on-year. Second, sustainable fashion has become a necessity. Searches for items made of organic cotton and recycled fabrics have risen by 120%, online transaction volume of second-hand luxury goods has exceeded 8 billion US dollars, and brands have launched "old clothes recycling for discounts" activities to drive repurchases. Third, "instant trend" consumption is emerging. Short video platforms have collaborated with e-commerce to launch the "24-hour delivery for popular style duplicates" service. For fast fashion items tailored to scenarios like music festivals and parties, the average time from order placement to delivery has been shortened to 18 hours, meeting the instant dressing needs of young people.
