When Shein first burst onto the scene, it seemed unstoppable. The Chinese-founded retailer redefined what was possible in fast fashion, uploading new items within hours and selling complete outfits for mere pounds. This was retail on overdrive, and millions of shoppers worldwide became hooked on the dizzying pace.
Now, something has changed.
Shein’s much-anticipated debut on the Hong Kong Stock Exchange this week fell flat. Shares dropped 6 per cent on opening day, a disappointing start for a company that was once valued at a staggering $100bn. Today, its market capitalisation sits at roughly a quarter of that figure—putting it on par with established names like H&M.
The company had previously attempted listings in both New York and London, only to be blocked or deterred by regulators. Concerns over supply chain practices and allegations of forced labour hampered its American ambitions, while UK officials raised questions about transparency. The Hong Kong listing represented something of a last resort.
A Business Built on Speed
Shein’s rise reads like a modern business fairy tale gone awry. Founded by Chris Xu in 2008 as a modest wedding dress venture, the company remained relatively unknown until the pandemic catapulted online shopping into the mainstream. Between 2018 and 2021, revenue exploded from $2bn to $15.7bn—an increase of 685 per cent.
The secret sauce was velocity. Following a “test and repeat” model also used by Inditex and H&M, Shein kept just 6 per cent of its inventory in stock for longer than three months. By the year ending March, the company had amassed more than 273 million active customers and processed over a billion orders.
Yet the model has faced mounting headwinds. Tariff exemptions on low-value goods in the United States and Europe have dried up, forcing Shein to raise prices. The company reported a $99m loss in the first quarter of this year, a dramatic reversal from the $395m profit posted during the same period in 2025.
Shein has also found itself plagued by controversies. In 2020, it faced backlash for selling swastika necklaces—an incident that prompted a swift apology and product removal. More recently, the company lost a copyright lawsuit against rival Temu, which stood accused of “industrial-scale” intellectual property violations.
The Sustainability Turning Point?
Yet perhaps the most significant pressure comes from shifting consumer values and tightening regulations.
Dr Rose Marroncelli, a senior fashion lecturer at Nottingham Trent University, believes Shein’s struggles may reflect broader changes in shopping habits. “Research indicates that Gen Z are becoming more environmentally conscious,” she notes. “Increasingly, they favour honest and transparent brands. They are widely characterised as a group that values authenticity and corporate accountability.”
The numbers bear this out. In the UK, two-thirds of consumers purchased second-hand goods online last year. Platforms like Vinted and Depop have seen revenues soar, with Vinted surpassing €1bn in revenue. Even luxury goods are increasingly bought pre-owned, with rare vintage pieces now more valuable than mass-produced designer items.
Governments are also cracking down. In the UK, the Competition and Markets Authority received significantly enhanced enforcement powers in 2025, equipping it to impose severe penalties for misleading environmental claims—commonly known as “greenwashing.” Shein has already felt the sting of regulatory action. The company was fined €1m in Italy for misleading environmental claims and hit with a €40m penalty from France’s consumer watchdog.
Oxfam’s annual Second Hand September campaign, now fronted by actor Richard E Grant, encourages shoppers to buy exclusively pre-loved clothing for at least 30 days. The initiative attracts thousands of participants annually.
Still, challenges remain. Lefties, a budget chain owned by Zara’s parent company Inditex, launched its first UK store in Liverpool last week, deploying robotics to keep costs low. Two more outlets are planned for next year.
Why it Matters
The fashion industry produces approximately 100 billion garments each year, with an estimated 92 million tonnes ending up in landfill. The UK alone sends 300,000 tonnes of clothing to waste disposal sites annually. If current trends continue, the Ellen MacArthur Foundation projects the fashion sector could account for 26 per cent of the world’s carbon budget by 2050.
Shein’s share price stumble may symbolise more than a single company’s fortunes. It could mark a inflection point in consumer attitudes and regulatory scrutiny that forces the entire industry to reckon with its environmental and ethical footprint. Whether this signals lasting change—or merely a temporary stumble for fast fashion—remains to be seen, but the direction of travel appears increasingly clear.
