High-quality development is a fundamental requirement of Chinese-style modernisation and a central theme of progress across all sectors in the new era. Brands represent excellence，and the cultivation of strong brands is essential to advancing high-quality development. From the perspective of the modern fashion industry，this research examines the defining characteristics of iconic international fashion brands such as Chanel and Hermès，including continuous innovation，exceptional quality，and trendsetting leadership. These attributes align closely with Shenzhen’s city identity as “Creative Shenzhen，Fashion Capital” and its aspiration to achieve high-quality development in the future. Brand cultivation should serve as a driving force for the high-quality advancement of Shenzhen’s fashion industry，integrating it as a vital component of the “20+8” emerging industry clusters and enhancing Shenzhen’s global image as a hub for international fashion. Successful brand cultivation requires a long-term commitment to brand culture and the pursuit of excellence through craftsmanship. Currently，Shenzhen’s fashion industry lacks representation among the Fortune Global 500 or the World’s Top 500 Brands. However，it has remarkable growth trajectory，substantial industry clusters，and unique advantages—such as its status as a UNESCO “City of Design，” an innovation hub，and its favourable business environment—there is a strong foundation for future success. Shenzhen will nurture and establish numerous globally influential and competitive fashion brands. This progress will solidify Shenzhen’s position as an emerging fashion industry leader and a world-renowned capital for cutting-edge fashion.
