China’s secondhand fashion market keeps growing, and it is not mainly because young shoppers suddenly care about the planet. Price matters more. National pride matters more. Sustainability is the story brands like to tell themselves about this market. It is rarely the reason someone opens Poizon or Xianyu on a Tuesday night.
Fake goods and shopper distrust still slow this market down, and they are the main reason some brands stay away from it entirely. In this piece, I look at who actually buys secondhand fashion in China in 2026, which platforms matter, how they fight counterfeits, and what a brand selling new products needs to understand before this parallel market eats into its sales, or quietly builds its next generation of buyers.
I have run GMA from Shanghai since 2012, and I have watched three of our fashion clients get undercut by their own secondhand listings before anyone on their team noticed the price gap. This is not a niche topic anymore. It is a pricing and distribution problem, and it deserves the same attention as your Tmall strategy.
What’s Actually Driving China’s Secondhand Fashion Boom
Younger Chinese consumers are the engine behind this market, but not for the reason most Western coverage assumes. Sustainability shows up in surveys. It rarely shows up in the shopping cart. What shows up in the shopping cart is a lower price on a bag or a pair of sneakers that would otherwise be out of reach, and a growing comfort with buying something someone else already owned.
That comfort is new. A decade ago, buying used goods carried a stigma in China that Western markets did not share to the same degree. That has flipped. Xiaohongshu and Douyin turned resale into content: unboxing a secondhand find, comparing it to the retail price, showing off the authentication tag. The purchase became something to post about, not something to hide.
Guochao Changed What Brand Loyalty Means
The bigger shift is guochao, the wave of pride in domestic brands that has reshaped Chinese consumer behavior since the early 2020s. It did not just push shoppers toward Chinese labels. It loosened their attachment to Western ones. A shopper who used to save for a full-price European handbag now treats that bag as one option among several, and buying it secondhand, or buying a domestic brand instead, both feel equally acceptable. Loyalty that used to be automatic now has to be earned every season, and foreign fashion brands that assumed otherwise have paid for it.
Add price sensitivity on top of that, and the math is simple. Even shoppers who can afford full retail price are increasingly choosing not to pay it. Two numbers make the scale clear. Xianyu, Alibaba’s general resale marketplace, reported monthly active users of 217 million in the 2025-2026 period, up 19.64% year on year, a growth rate that outpaced most mainstream e-commerce apps according to QuestMobile data reported by Sina Finance. Among Gen Z users specifically, Xianyu’s monthly actives reached 43.6 million, growing 47.1% year on year, faster than Taobao, JD.com or Pinduoduo among that age group.
The Three Platforms That Actually Matter
Foreign brands often lump “Chinese secondhand” into one category. That is a mistake. Three platforms dominate, and they serve completely different shoppers.
得物 (Dewu, sold internationally as Poizon) owns streetwear and sneakers. It started as an authentication app for sneaker resale and grew into a full marketplace, and it still leads with verification as its core promise. At its 2026 all-staff meeting, the company disclosed that its app user base had passed 600 million, with 70% of users under 30, and that its paid authentication service had grown 184% year on year, having completed more than 1.3 billion cumulative verification checks across 186 countries, according to company figures reported by Chinese business media. If your product is streetwear, sneakers, or anything with hype value, resale conversation about your brand is happening here whether you participate or not. One European streetwear brand went viral on the platform without spending a euro on it, purely from community resale activity.
红布林 (Plum) is the specialist for actual luxury: bags, watches, jewelry. It built its name on manual grading and authentication by category experts, a process that historically took about a day and a half per item. In 2025, Plum was fully absorbed by 转转 (Zhuanzhuang), one of China’s larger secondhand platforms, and its luxury authentication know-how was folded into Zhuanzhuang’s own verification system. Both companies were named among the first pilot enterprises for regulated secondhand goods circulation at the China International Consumer Products Expo in April 2025, a sign that Beijing now sees this market as worth formalizing rather than ignoring, per 21st Century Business Herald’s coverage of the deal.
闲鱼 (Xianyu, Idle Fish) is Alibaba’s generalist marketplace, and by volume it is the biggest of the three. Registered users are past 600 million, with more than 4 million new listings posted daily and daily transaction value above 10 billion yuan. It sells everything from used furniture to bags to electronics, which makes it the widest net for reach but the weakest for curated trust. A fake bag can sit next to a genuine one with no platform-level check forcing the distinction. For a brand watching where its own products resurface, Xianyu is where the volume lives, but it is not where a shopper goes looking for a guarantee.
| Platform | Best for | 2026 user base | Trust model |
|---|---|---|---|
| 得物 Dewu / Poizon | Streetwear, sneakers, hype goods | 600M+ app users, 70% under 30 | In-house paid authentication, AI plus human review |
| 红布林 Plum (now under 转转 Zhuanzhuang) | Luxury bags, watches, jewelry | Merged into Zhuanzhuang’s user base in 2025 | Manual expert grading, roughly 1.5 days per item |
| 闲鱼 Xianyu / Idle Fish | General resale, high volume | 600M+ registered users | Seller-declared, limited platform verification |
Authentication Is Still the Real Barrier to Trust
Fake goods are the reason some shoppers still avoid secondhand platforms entirely, and the reason some luxury brands still refuse to engage with this market. That distrust is rational. It is also shrinking, slowly, as platforms invest real money in solving it.
The 184% growth in Poizon’s paid authentication service is not just a business metric. It shows shoppers are increasingly willing to pay extra for a verification step, which means they do not fully trust a listing without one. Platforms have responded with a layered approach: AI image comparison against a database of known genuine items as a first pass, human experts for anything the AI flags or for high-value categories, and increasingly, physical proof, tags, chips, or certificates that travel with the item after the sale. Zhuanzhuang folding Plum’s manual grading process into its own system fits the same logic: centralize expertise instead of leaving verification to individual sellers.
Brands can speed this up themselves. Hermès has run public awareness campaigns in China and worked directly with authorities to shut down counterfeit workshops, an approach that protects the brand’s resale value as much as its retail sales. A bag that holds its resale price because buyers trust it is genuine is a bag that is easier to sell new, too. Brands that ignore counterfeiting on the resale side are, in effect, letting fakes set the market’s perception of their quality.
What This Means If You Sell New
The honest answer is both. Secondhand can cannibalize your new sales, and it can also build your next generation of buyers. Which one happens depends on how you manage it, not on whether the market exists. It exists either way.
Cannibalization is real when your resale prices sit too close to retail, when your own product floods Xianyu because your distribution partners are overstocked, or when counterfeit listings under your name are convincing enough that shoppers stop trusting the “genuine” label altogether. If a buyer can get 80% of the experience for 40% of the price, on a platform with no waiting list and instant delivery, some of them will take that deal every time.
Noemie, a French accessories brand founder, came to us after noticing her bestselling bag was listed on Xianyu at nearly full price, barely used, faster than her own restocks could sell out. Her first instinct was to fight the listings. That did not work: sellers just relisted under different titles. What worked was different. She started tracking resale prices on Poizon and Xianyu every month, used the data to see which SKUs held value best, and leaned into those for her next collection instead of guessing. She also opened an official account on Poizon offering authentication certificates for her own products, which made genuine resale listings easier to trust and counterfeit ones easier to spot. Six months later, her resale prices had stabilized close to retail instead of undercutting it, and new orders from buyers who said they discovered the brand through a secondhand listing accounted for about 12% of new sales that quarter. The mechanism was simple: when resale holds its value, it stops looking like a discount and starts looking like proof the brand is worth buying new.
The same tension shows up in a completely different category. China’s secondhand luxury car market is being reshaped by cheap domestic EVs and certified pre-owned programs from international brands, a different set of forces than fashion, but the same underlying question: does a brand fight its own resale market, or build a certified pre-owned channel it controls? Some carmakers now run their own certified secondhand programs rather than leave the resale conversation to third parties. There is no reason a fashion or luxury brand could not do the same thing on Poizon or Plum.
What you should not do is ignore it. A brand with no visibility into its own resale prices, no relationship with the top verification platforms, and no answer for “is this real” finds out about the problem only after resale has already eaten into its position in China’s luxury market.

Frequently Asked Questions
Is secondhand fashion in China only for young, budget-conscious shoppers?
Mostly, but not only. Shoppers under 30 make up the majority on platforms like Poizon, and price is the main driver. But older, higher-income buyers use Plum specifically for luxury pieces, often because a well-graded secondhand item comes with a level of authentication assurance that some grey-market retailers cannot match.
Will secondhand marketplaces cannibalize my new product sales in China?
It depends on your pricing gap. If secondhand listings sit close to retail because your product holds value, resale acts as proof of quality and can bring in new buyers. If the gap is large, because of overstock, weak demand, or counterfeits, resale competes directly with your new sales. Track your own resale prices monthly rather than assuming either outcome.
How do platforms like Poizon and Plum verify authenticity?
Poizon combines AI image matching against genuine reference items with human experts for flagged or high-value cases, plus a paid certification service. Plum’s process, now run under Zhuanzhuang, relies on manual grading by category specialists, typically completed within about a day and a half per item. Neither system is perfect, but both are investing heavily in it because trust is their main product.
Should my brand have an official presence on Xianyu or Poizon?
If you sell anything with resale value in China, streetwear, sneakers, bags, watches, yes, at minimum monitor what is listed under your name. An official authentication offering, even a simple one, gives you a way to separate genuine resale from counterfeit and turns a market you do not control into one you can at least see clearly.
