NUMBERSSecondhand is now 12 percent of the American closet
The market crossed a threshold worth pausing on: US secondhand fashion sales reached 55.5 billion dollars in 2025, which works out to 12 percent of the 458 billion dollars Americans spent on clothing, footwear, and accessories, according to ThredUp’s 14th annual Resale Report with GlobalData. The sector grew 14 percent last year, roughly four times the pace of the primary market, and is projected to approach 80 billion dollars by 2030.
The raw dollars understate the shift, because secondhand goods cost 60 to 75 percent less than new: measured in items moved and consumers reached, resale is much bigger than its revenue line. About 60 percent of American consumers bought secondhand in 2025. This is no longer an alternative channel. It is a parallel apparel economy.
MARKETThe K-shaped economy is resale’s growth engine
Bank of America Institute card data shows secondhand fashion transactions up 22 percent year over year in March, inside an overall clothing spend increase of 5.1 percent that ended nearly three years of declines. The distribution is the story: growth concentrated at the two ends, discount apparel up over 4 percent quarter over quarter while secondhand luxury spending jumped fivefold in the same span.
Top earners are trading into pre-owned Chanel and Hermes; stretched households are trading down. Both roads lead to resale. One more signal buried in the data: Gen Z now makes up 41 percent of Bank of America customers selling secondhand, meaning the youngest cohort is using resale platforms as income, not just savings.
BRANDSBranded resale grew 300 percent, and most brands still cannot run it
Brand-operated resale sales grew 300 percent between 2021 and 2025, according to the BoF-McKinsey State of Fashion 2026, yet only 16 percent of surveyed fashion brands say they are ready to scale resale immediately, with 38 percent blocked by logistics and operations.
That gap is the business opportunity of the moment, and it belongs to the resale-as-a-service layer: ThredUp powering J.Crew, Madewell, Athleta, and Tommy Hilfiger; Trove behind Patagonia, Levi’s, and Canada Goose; Archive running programs for Lululemon and The North Face. The brands get the customer relationship and the sustainability story. The infrastructure players get recurring revenue from every one of them. In gold rush terms, the RaaS providers are selling shovels.
PLATFORMSThe curation pivot: resale stops competing on size
For two decades secondhand platforms competed on selection: more listings, more brands, more inventory. That race is ending. ThredUp, eBay, StockX, and Rebag are now working to differentiate on curated experience instead, deploying AI and celebrity partnerships to surface less and sell more, according to Business of Fashion reporting. The logic is defensive as much as strategic: when every platform holds millions of listings, breadth stops being an advantage and starts being a search problem.
Europe already previewed where this goes. Vinted, the volume king, became France’s top retailer by unit volume while growing net profit over 330 percent between 2023 and 2024, proving scale wins the mass tier. Everyone who cannot out-scale Vinted has one move left: taste.
RESEARCHThe sustainability story has a crack in it
A study coauthored at Yale and published in Scientific Reports surveyed over 1,000 US consumers and found that heavy secondhand shoppers also buy more new clothing, not less. The researchers point to a rebound effect, where cheaper secondhand goods increase total consumption, and moral licensing, where a virtuous thrift purchase justifies the next new one. A 59 percent cluster of respondents reported high consumption in both markets at once.
Why it matters for the industry: the sustainability narrative is resale’s political shield and marketing engine, and researchers are now calling for platforms to disclose unsold inventory disposal rates and shipping emissions. No regulation of the secondhand chain currently exists in the US or Europe. If that changes, disclosure will be the first battleground, and the platforms with clean numbers will want it.
