In just over a decade, Shein has transformed from an obscure Chinese wedding dress retailer into a global fast fashion powerhouse, outpacing established giants like Zara and H&M. With its revolutionary business model powered by artificial intelligence, real-time data analytics, and on-demand manufacturing, Shein has redefined the fast fashion landscape. This article explores Shein’s remarkable journey, innovative strategies, and the challenges it faces as it prepares for a potential IPO while navigating environmental concerns and changing trade policies.
From Humble Beginnings to Global Dominance
Founded in Nanjing, China, in 2008 by Chris Xu, a search engine optimization specialist, Shein (pronounced “she-in”) began as a cross-border e-commerce site selling wedding dresses. The company has enjoyed eight consecutive years of over 100% revenue growth, transforming from a low-cost Chinese apparel merchant into a global fashion juggernaut.
Shein’s growth has been nothing short of spectacular. Its sales skyrocketed from $10 billion in 2020 to a remarkable $100 billion in 2022, making it the world’s most popular fashion brand. More recent figures show that Shein generated an estimated $32.5 billion in 2023, representing a 43% increase from the previous year.
What’s particularly noteworthy is how Shein thrived during the COVID-19 pandemic while traditional retailers struggled. When most American fashion companies were caught off guard by the impact of COVID-19 and the overall US apparel and footwear market declined by over 20% in 2020, Shein’s sales grew dramatically by 150% compared to 2019.
The “Real-Time Retail” Revolution
At the heart of Shein’s unprecedented success is its revolutionary “real-time retail” model, which fundamentally transforms how fashion is designed, produced, and sold. Analysts have called Shein’s business model “real-time retail” because it can create new designs in as little as three days, compared to the weeks or months required by traditional retailers.
The company employs a unique “test-and-learn” approach to minimize waste and maximize efficiency. By piloting new styles with fewer than 200 units and only producing more based on demand, Shein efficiently matches supply to demand, reduces costs, and minimizes waste. This stands in stark contrast to traditional retailers who typically order thousands of units per style months in advance, hoping they’ll sell.
Shein’s product variety is staggering. Unlike traditional retail giants like Zara and H&M, which follow a seasonal production cycle, Shein operates on an ultra-fast fashion model, with advanced automated systems enabling it to produce and list over 1.3 million new items annually. On an average day, the company adds 2,000 new items to its store.
AI-Powered Fashion: The Technology Behind Shein’s Success
Artificial intelligence is the driving force behind Shein’s ability to identify and capitalize on fashion trends with unprecedented speed. By using proprietary machine-learning algorithms, the company can analyze real-time customer preferences and anticipate demand, allowing for fast production cycles.
This technology-driven approach has revolutionized trend forecasting. Unlike traditional fashion companies, Shein, a digital native, uses real-time online shopping behavior to identify emerging looks, transforming trend forecasting from a long-term gamble to an immediate strategy.
Shein has created a tightly integrated supply chain powered by its proprietary software. During a retail conference in Berlin in January, Peter Pernot-Day, Shein’s head of global strategy and corporate affairs, explained that more than 5,000 Shein suppliers recently gained access to an AI software platform to analyze customer preferences. This technological integration enables the company to respond to customer preferences with unprecedented speed.
In April 2025, Shein executives continued to emphasize their technology-focused approach. At the Retail Technology Show in London, Peter Pernot Day described Shein’s model as “smart fashion, not fast fashion,” highlighting their unique, demand-based supply chain.
The Social Media Marketing Machine
Shein’s marketing strategy places social media at the center, particularly targeting Generation Z consumers. The company has poured millions into Google and Facebook campaigns, advertisement deals, and even a social media reality show co-hosted by Khloé Kardashian.
The cornerstone of Shein’s marketing approach is its collaboration with influencers. The company partners with countless micro-celebrities, fashion bloggers, and reality show contestants who show off their Shein deliveries in #SHEINhaul videos. This strategy has been wildly successful, with these videos generating billions of views across platforms like TikTok and Instagram.
Shein’s focus on digital marketing has given it a significant advantage over traditional retailers. Mintel’s latest womenswear brand research shows that Shein is seen as stylish due to its ability to keep up with the newest fashion trends, but unlike ASOS, it also benefits from being perceived as a brand that offers good value.
Global Reach and Market Dominance
Shein has rapidly expanded its global footprint, now operating in over 150 countries. The company’s U.S. sales roughly doubled between March and April 2020, and by November 2022, Shein accounted for 50 percent of sales among major fast fashion competitors in the United States.
The company has particularly resonated with young consumers worldwide. Shein has an estimated 88.8 million active shoppers, with 17.3 million based in the US. Its mobile app was downloaded 238 million times in 2023, making it the most downloaded fashion app of that year.
Market research highlights Shein’s growing dominance. In November 2022, Shein’s share of U.S. fast fashion sales was 50%, followed by H&M at 16%, Zara at 13%, Fashion Nova at 11%, Forever 21 at 6%, and ASOS at 4%.
IPO Plans Amid Changing Regulatory Landscape
As Shein prepares for a potential Initial Public Offering (IPO) in London, the company faces significant challenges from changing trade policies and regulatory scrutiny. In April 2025, Shein secured approval from Britain’s Financial Conduct Authority (FCA) for its planned IPO in London, marking a significant step forward after shifting away from its earlier attempts to list in the United States.
However, recent changes to U.S. trade policies have created headwinds for the company. The company’s business prospects have come under a cloud after the Trump administration said it would close the “de minimis” duty exemption in the United States, ending an import rule that had helped Shein keep prices low.
These policy changes have impacted Shein’s valuation prospects. The imposition of tariffs on small packages imported to the United States from China reportedly led Shein to consider cutting its valuation in a potential London IPO by nearly 25%, from $66 billion to around $50 billion. Some reports even suggest pressure from investors to cut the valuation further to $30 billion.
In response to these challenges, Shein is weighing a restructuring of its U.S. operations as the tariffs on Chinese imports threaten to jeopardize its London IPO. One option being considered is shifting production for the U.S. market.
Environmental and Ethical Challenges
Despite its remarkable success, Shein faces growing criticism regarding its environmental impact and labor practices. In 2023, the fast fashion giant Shein nearly doubled its carbon dioxide emissions between 2022 and 2023, making it the biggest polluter in the fashion industry.
Shein’s transportation methods contribute significantly to its carbon footprint. About 38 percent of Shein’s climate footprint comes just from transportation—mainly air freight. The company provided carriers with approximately 900,000 packages daily in the U.S. in July 2024 alone.
Labor conditions in Shein’s supply chain have also come under scrutiny. Reports indicate that workers log up to 75-hour work weeks, raising questions about the company’s commitment to improving working conditions.
In response to these concerns, Shein has announced sustainability initiatives, including a new product line called “evoluSHEIN” in 2022, which uses environmentally friendly materials. The company has also set ambitious targets: a 25% reduction in carbon emissions by 2030 and net-zero emissions by 2050.
The Future of Fast Fashion
As Shein continues to evolve, the company faces both opportunities and challenges in shaping the future of fast fashion. In 2025, there are signs of changing consumer preferences. Shein customers are beginning to allocate more of their fashion budgets to brands like Quince, which sells luxury basics at low prices by cutting out middlemen and streamlining its supply chain.
Meanwhile, artificial intelligence continues to transform the fashion industry beyond Shein. AI is revolutionizing the industry by forecasting demand accurately, optimizing inventory levels, enhancing sustainability, ensuring quality control, and supporting ethical practices.
The broader AI landscape in 2025 shows increasing adoption across industries. In the latest survey, 78 percent of respondents say their organizations use AI in at least one business function, up from 72 percent in early 2024 and 55 percent a year earlier.
Despite its challenges, Shein’s innovative business model and technological capabilities have permanently changed the fashion industry. As it navigates regulatory hurdles, environmental concerns, and evolving consumer preferences, Shein’s ability to adapt and innovate will determine whether it can maintain its position as the world’s leading fast fashion retailer.
