The Secondhand Revolution

Why Resale and the Circular Economy Are Rewriting Retail’s Playbook

I am someone who appreciates things that age. I like vintage cars, birth year watches, and leather that tells a story. Traditionally retail has favored fast and seasonal over substance, but something fundamental has shifted in fashion retail, and no amount of new-season lookbooks can reverse it. Secondhand is no longer the scrappy underdog of the apparel world. It is, by almost every measurable metric, one of the most powerful growth vectors in global retail. For brands and retailers still treating resale as a niche sustainability gesture, the data is telling a different and more urgent story.

Let’s get into it…….

The Numbers Do Not Lie

The global secondhand apparel market grew 12% in 2025 to approximately $289 billion and is now projected to reach $393 billion within five years, according to ThredUp’s annual resale report. To understand the scale of that trajectory, consider that U.S. resale grew nearly four times faster than the broader retail clothing market in 2025. The sector is expanding at a pace 2.7 times faster than the overall global apparel industry. By 2029, online resale alone is expected to nearly double, hitting $40 billion with an annualized growth rate of 13%.

These are not vanity projections. They reflect a genuine and accelerating structural shift in how consumers think about getting dressed, spending money, and expressing identity. In 2024, 58% of U.S. consumers bought secondhand clothing, a record high and a 6% jump from the prior year. A quarter of American consumers actively resold apparel in the same period. Resale now represents 9% of global apparel spending, up from a marginal share just a decade ago. The secondhand revolution is no longer a niche trend. It is a core pillar of the fashion ecosystem.

The Perfect Storm: Tariffs, Inflation, and the Thrift Pivot

No trend exists in a vacuum, and resale has benefited from a powerful convergence of macroeconomic forces. Tariffs on imported apparel have become a meaningful tailwind for the secondhand category. The U.S. government imposed $1.9 billion in additional taxes on clothing and shoes between May and June 2025 alone, pushing average tariff rates above 25%, nearly double what they were a year earlier. The knock-on effect has been material: Reuters reported that Zara prices in the U.S. rose 28% year-over-year in June 2025, driven largely by tariff exposure.

Consumers have noticed. ThredUp’s 2025 Resale Report found that 62% of consumers said they are worried tariffs will make apparel more expensive, and six in ten indicated they would respond by shopping more secondhand. Among millennials, that figure climbs to 69%. Gen Z, already the demographic most likely to shop pre-owned, has signaled they would shift spending to secondhand at even higher rates if tariffs drive up the cost of new goods. The de minimis exemption, which previously allowed parcels under $800 to enter the U.S. duty-free and propped up ultrafast fashion players like Shein and Temu, is now under pressure. For domestic resale platforms with U.S.-based inventory and infrastructure, that is a competitive advantage that did not exist three years ago.

Inflation has compounded the effect. As household budgets tighten, resale platforms offer an increasingly attractive value proposition: brand-name goods at meaningful discounts, with a growing sense of cultural legitimacy that the stigma-reduction data confirms. A 2024 survey found that 72% of respondents believe resale stigma has decreased over the prior year, a dramatic shift in social perception that makes the trade-in and resale conversation far easier for mainstream retailers to initiate with their customers.

AI Is the Engine Behind the Scale

If macroeconomic pressure is providing the demand, artificial intelligence is solving the supply-side challenge that previously kept resale from scaling like traditional retail. Every pre-owned item is unique. Pricing it, tagging it, photographing it, and surfacing it to the right buyer at the right moment requires a volume and speed of decision-making that human labor alone cannot deliver profitably.

ThredUp, which processes millions of garments annually, has invested more than $400 million in supply chain automation covering item identification, measurement capture, and dynamic pricing. The result: the company posted 79.5% gross margins in Q2 2025. Traditional apparel retailers rarely exceed 30%. That margin gap is the story of what AI-enabled operational leverage can do in a category built on one-of-a-kind inventory.

The technology is also reshaping the consumer experience. AI-driven tools are making personalization, search, and discovery on resale platforms increasingly frictionless. ThredUp reports that 48% of consumers now say that AI-powered personalization makes shopping secondhand as easy as buying new, a figure that climbs to 59% among Gen Z and millennials. Beni, an AI-powered resale search engine, launched Beni Lens, a visual identification tool allowing users to photograph a garment and instantly receive curated listings across multiple platforms filtered by size, price, and brand. Phia, co-founded by Phoebe Gates and Sophia Kianni, uses AI to scan thousands of listings across both retail and resale simultaneously. Discovery is no longer the barrier it once was.

For retailers building branded resale programs, AI is equally critical behind the scenes. Companies like Trove and Archive have built resale-as-a-service infrastructure that allows brands to outsource the operational complexity while retaining the customer relationship and brand equity. Trove’s platform, which powers programs for Canada Goose, Lululemon, and Patagonia, uses AI to categorize inventory and power personalized resale experiences at scale.

Retailers Lean In: The Certified Pre-Owned Opportunity

The most strategically interesting development in this space is not what third-party platforms are doing. It is what brands and retailers are doing to internalize the resale opportunity rather than cede it to the open market. As of 2025, 153 U.S. fashion brands have resale listings on their e-commerce sites, a 325% increase since 2021. Among the top 50 U.S. fashion brands surveyed by Fashion Dive, executives at 74% of companies without an existing in-house resale channel said they are considering adding one.

The brands that have already moved are instructive. H&M’s Pre Loved program opened a second shop-in-shop in Beverly Hills in November 2025 and reported a significant sales increase from Q2 to Q3 2025 at its Soho NYC pilot location. Zara expanded its Pre Owned platform, which launched in the U.K. in 2022, to additional major markets with a stated goal of reaching all major Zara markets by the end of 2025. Levi’s SecondHand program focuses on authenticated vintage and refurbished denim, leaning directly into the brand’s heritage. Patagonia’s Worn Wear program, one of the earliest at scale, now features a Resale Plugin allowing pre-owned items to be embedded directly alongside new products on product pages, with the ability to check out both in a single cart.

Patagonia’s revenue from Worn Wear is still around $5 million annually as of 2024, modest relative to the company’s overall scale but meaningful as proof of concept and brand signaling. Mid-market branded resale programs broadly have seen a 300% increase in sales between 2021 and 2025, according to McKinsey and Business of Fashion’s State of Fashion 2026 report.

In the luxury segment, the dynamic is sharper and the stakes are higher. Rolex built a certified pre-owned pathway that brings resale under formal brand oversight, requiring eligible watches to be authenticated and serviced through official workshops before resale through authorized retailers. The move is explicit acknowledgment that the secondary market is too large and too brand-relevant to leave uncontrolled. Selfridges’ Resell initiative spans resale, repair, refill, rental, and pre-loved buying. Bergdorf Goodman’s Conscious Closet program covers edit, repair, alter, resell, and donate services through a coordinated in-house and partner network. These are not sustainability experiments. They are mechanisms for extending brand and retailer relevance across the full product lifecycle and across multiple ownership cycles.

Luxury brands are divided on how to respond to resale’s acceleration. Some, like Rolex, have built certified pre-owned programs. Others, like Kering, are approaching resale through capital deployment, having led a $216 million funding round in Vestiaire Collective. Still others are using litigation, as Chanel has done, to define the boundaries of secondary-market engagement. The common thread is that no major luxury brand can afford to treat resale as someone else’s problem anymore.

What This Means for Retailers: Strategic Calculus

The fear of cannibalization is the most common objection raised by retail executives when evaluating resale investment. It is understandable but increasingly unsupported by data. Resale serves as a gateway rather than a replacement: 43% of secondhand shoppers later purchase first-hand products from the same brand, according to the State of Fashion 2026 report. The customer acquired through a pre-owned channel becomes a full-price customer down the line. That is a customer acquisition mechanic, not a revenue cannibalization risk.

Retailers also need to weigh resale’s role as a supply stabilizer. In a tariff-uncertain environment, 54% of retailers now view resale as a stable and predictable supply source, according to eMarketer. Pre-owned inventory is domestically sourced and insulated from import cost volatility. That is operationally significant at a moment when new-goods supply chains remain exposed to geopolitical and trade policy risk.

The infrastructure question is real, however. For fast-fashion retailers with high turnover, low-durability products and thin margins, the economics of branded resale are genuinely difficult to make work. The research confirms that resale programs are most viable and most carbon-impactful for brands whose products are durable, brand-identified, and carry meaningful resale value. Premium, outdoor, and luxury segments have a natural structural advantage here.

The Sustainability Paradox

There is an honest tension at the center of this trend that the industry has not fully resolved. A December 2025 Yale study found that more than 59% of survey respondents reported high consumption levels in both new and secondhand clothing. Resale is growing, but so is overall apparel purchasing. Lynda Grose, a professor of fashion design and critical studies at California College of the Arts, put it plainly: “The growth in secondhand is an additive business for companies. It is not displacing the business of producing new goods.”

The implication is that certified pre-owned and branded resale programs, while genuine progress, do not automatically reduce the industry’s total environmental footprint. For brands serious about circularity as a climate strategy rather than just a brand positioning tool, resale must eventually be paired with deliberate reductions in new production volume. That is a harder conversation and one that few publicly traded retailers are yet willing to have at scale.

But even within that constraint, the direction of travel is clear. Resale is growing. AI is making it operationally viable at retail scale. Macroeconomic conditions are accelerating adoption across income demographics and age groups. Retailers that build the capability now, through in-house programs, technology partnerships, or certified pre-owned infrastructure, will be better positioned for a market in which secondhand is not a supplement to the primary channel but an equal part of the shopping journey.

The brands treating resale as a checkbox are already behind. The ones treating it as a business model are building the next chapter of retail.
