Fast fashion is far from green. But the rapid expansion of online clothing resale platforms could help shrink the garment industry's negative impact on the environment

A massive force is reshaping the fashion industry: secondhand clothing. According to a new report, the US secondhand clothing market is projected to more than triple in value in the next 10 years – from US$28 billion in 2019 to US$80 billion in.
In 2019, secondhand clothing expanded 21 times faster than conventional apparel retail did.
Even more transformative is secondhand clothing’s potential to dramatically alter the prominence of fast fashion – a business model characterized by cheap and disposable clothing that emerged in the early 2000s, epitomized by brands like H&M and Zara. Fast fashion grew exponentially over the next two decades, significantly altering the fashion landscape by producing more clothing, distributing it faster and encouraging consumers to buy in excess with low prices.
While fast fashion is expected to continue to grow 20% in the next 10 years, secondhand fashion is poised to grow 185%.
As researchers who study clothing consumption and sustainability, we think the secondhand clothing trend has the potential to reshape the fashion industry and mitigate the industry’s detrimental environmental impact on the planet.
More mindful consumers?
The fashion industry has long been associated with social and environmental problems, ranging from poor treatment of garment workers to pollution and waste generated by clothing production.
Less than 1% of materials used to make clothing are currently recycled to make new clothing, a $500 billion annual loss for the fashion industry.
The textile industry produces more carbon emissions than the airline and maritime industries combined. And approximately 20% of water pollution across the globe is the result of wastewater from the production and finishing of textiles.
Consumers have become more aware of the ecological impact of apparel production and are more frequently demanding apparel businesses expand their commitment to sustainability. Buying secondhand clothing could provide consumers a way to push back against the fast-fashion system.
Buying secondhand clothing increases the number of owners an item will have, extending its life – something that has been dramatically shortened in the age of fast fashion. (Worldwide, in the past 15 years, the average number of times a garment is worn before it’s trashed has decreased by 36%.)
High-quality clothing traded in the secondhand marketplace also retains its value over time, unlike cheaper fast-fashion products. Thus, buying a high-quality secondhand garment instead of a new one is theoretically an environmental win. But some critics argue the secondhand marketplace actually encourages excess consumption by expanding access to cheap clothing.
Our latest research supports this possibility. We interviewed young American women who regularly use digital platforms like Poshmark.
They saw secondhand clothing as a way to access both cheap goods and ones they ordinarily could not afford. They did not see it as an alternative model of consumption or a way to decrease dependence on new clothing production.
Whatever the consumer motive, increasing the reuse of clothing is a big step toward a new normal in the fashion industry, though its potential to address sustainability woes remains to be seen.
