A new default, not a backup plan
For most of retail history, buying secondhand was something shoppers did after new โ to save money, to hunt a vintage piece, or to be sustainable. For a growing share of Gen Z, that order has flipped. Secondhand is now the first stop, and "new" is the fallback when resale doesn't have what they want. This is the resale-first shopper, and she is reshaping how apparel brands should think about value.
ThredUp's 14th Annual Resale Report (2026), produced with GlobalData from a survey of 3,268 U.S. consumers, projects the global secondhand apparel market will reach $393 billion by 2030, representing roughly 10% of total apparel spend and growing about twice as fast as the overall apparel market. In the U.S., secondhand grew nearly 4x faster than broader retail clothing in 2025, with curated resale up 19% and online resale expected to approach $48.3 billion by 2030.
How Gen Z actually behaves
The report's most striking finding is where secondhand sits in the journey. 46% of consumers browse resale before buying new, and among younger shoppers the tilt is dramatic: 58% of Gen Z shopped secondhand in 2025, and 55% of both Gen Z and Millennials now prioritize secondhand over new. A separate ThredUp Gen Z study cited in industry tracking found 89% of Gen Z are either already thrift shoppers or open to it, with 63% actively preferring used over new.
Crucially, the behavior has matured. Gen Z has moved from high-volume "hauls" to deliberate "holy grail" hunting โ targeting specific brands and pieces rather than buying indiscriminately. That makes them discerning customers who know exactly what they want, and who treat their closets as tradable assets.
The resale flywheel changes new purchases too
Resale isn't only cannibalizing new sales; it's rewriting how the youngest shoppers evaluate new ones. ThredUp found 60% of customers say resale value is a key factor when buying new apparel (up 13 points year over year), and 39% would buy new specifically because it has high resale value. Among Gen Z, 67% consider resale value before a purchase. The closet has become a portfolio.
For brands, the implication is uncomfortable but clear: a garment's second life is now part of its first-sale pitch. Pieces that hold value, photograph well, and are built to last earn a pricing premium because the buyer knows she can recoup part of the cost later.
What this means for a new-inclusive brand
You don't have to run a resale platform to win this shopper. You win by building garments worth keeping and worth passing on: honest fabric composition, durable construction, and timeless silhouettes rather than disposable trends. A capsule that survives three owners is more valuable than a haul that survives one season.
We design with that longitude in mind. Our sale finds and bestsellers are chosen for pieces that hold their shape and their appeal โ the kind of wardrobe you buy once and wear for years, whether your next move is to keep, restyle, or resell.
Supply, not demand, is the bottleneck
Resale's constraint in 2026 is no longer interest โ it is inventory. ThredUp's report makes clear that demand for secondhand is established and growing, but the operational friction of listing, pricing, and shipping used goods limits how much actually reaches buyers. For shoppers, that means the best pieces get snapped up fast, and the "holy grail" hunt can take patience. For brands, it is a reminder that the resale flywheel depends on a steady flow of quality supply, which is exactly why durable, desirable new garments feed the cycle rather than fight it.
The brands that understand this design for longevity. A piece built to survive three owners is more valuable at every stage of its life than a trend built to be discarded after one season. It also means resale is becoming a discovery channel in its own right: shoppers browsing Depop or ThredUp for a specific brand often convert into new customers once they trust the fit.
