Olivia May, Partner at OC&C Strategy Consultants, looks at what the explosion of the fashion resale market means for traditional retail.
For a long time, “second-hand” sat in a different mental box to “retail”. It was charity shops, car-boot bargains and the occasional vintage find. Today, it’s one of the most dynamic parts of fashion commerce – and it’s happening largely online, with a customer experience that increasingly feels as slick as buying new.
The headlines make the point clearly. Vinted is now the third-largest fashion retailer in the UK by customer numbers, behind Primark and Next – and in a move that signals how strategically important the space has become, eBay has agreed to acquire Depop from Etsy for around $1.2bn, bringing a distinctly Gen Z resale community into eBay’s orbit. The move underlines that scale players believe resale has headroom to grow beyond the ~€5bn of market value spent on online second-hand fashion today in the UK.
The headlines also reinforce that the future of resale is not “scrappy peer-to-peer”. The best platforms are investing heavily to remove friction and build trust: smoother payments, better tracking, clearer issue resolution and stronger authentication flows. That’s what makes second-hand feel mainstream, and what makes it increasingly competitive with first-hand ecommerce.
For traditional retailers – particularly those built around ecommerce growth – this is no longer a trend to watch from the sidelines. Resale is shifting consumer expectations, diverting spend, and raising the bar on what “good” looks like in discovery, value, trust and sustainability. The winners will be the retailers who treat resale as a structural change and respond across operations, sales and marketing, and not as a bolt-on initiative.
The digital shift: resale is growing where ecommerce is strongest
One reason resale is so disruptive is that it scales beautifully online. Marketplaces can grow inventory without manufacturing. They can expand categories without building new supply chains. And they can monetise participation on both sides of the transaction.
In the UK, online second-hand fashion sales are expected to reach ~€7bn by 2029, and 35% of brits have now bought or sold second hand apparel online, a sign that resale is now a mass behaviour, not a niche hobby.
Fashion is at the centre of this shift, and the competitive implications are direct: if customers are increasing the share of their wardrobe spend that goes to resale, first-hand demand doesn’t need to collapse for retailers to feel the pinch. Even modest diversion of volume can be painful in a category already wrestling with heavy promotional intensity and rising operational costs.
What resale platforms are teaching customers to expect
Traditional retailers should pay attention to what the leading resale players are getting right – because these expectations will bleed into first-hand shopping.
1) Frictionless selling creates better buying
The secret engine of resale is supply. Platforms that make listing quick, pricing intuitive, shipping easy and payout trustworthy tend to win because they create more inventory, more trusted condition-standards, more variety and better sell-through.
2) Trust is becoming productised
Tracking, buyer protection, seller ratings, condition reassurance, payment escrow-style flows, dispute resolution and authentication services all reduce perceived risk. As these features improve, the “but is it safe?” objection fades, and resale becomes an everyday default.
3) Discovery is entertainment
Resale marketplaces often feel closer to social browsing than catalogue shopping, driving frequency, impulse and community, especially among younger shoppers.
4) Marketing spending is highly disciplined
Investing heavily to acquire buyers when you have limited or irrelevant items to sell is a recipe for CAC/LTV dilution. The best platforms are channelling their marketing dollars to convert buyers into sellers, to help compound stock liquidity, improve conversion and satisfaction, whilst structurally lowering acquisition costs.
When resale works for retailers – and when it doesn’t
There’s a temptation to see resale as a universal play. In reality, participation needs to be strategic, because profitability can be hard to achieve if the model is poorly matched to the brand.
Resale tends to work best when retailers have some combination of:
- Strong brand equity and durability (items retain value and shoppers trust the quality)
- Healthy margin structure (enough headroom to fund processing, refurbishment or incentives)
- A product that benefits from “certification” (e.g., verification, repair, cleaning, reconditioning)
- A reason to keep customers inside the ecosystem (trade-in credit, membership perks, access to drops)
This is why the success stories often come from brands with meaningful resale value and a clear proposition (think premium denim, heritage footwear, outdoor gear).
Where retailers struggle is when the economics don’t stack up: low AOV, low retained value, high reverse logistics costs, unpredictable grading, or a brand position that relies on “newness” rather than longevity.
The key point: resale can’t be treated as a marketing campaign. It’s an operating model.
How retailers should respond: operations, sales and marketing
1) Operations: partner into or build the circular supply chain
Resale introduces new motions: take-back, inspection, grading, refurbishment, photography, re-listing, storage, and second outbound delivery. Retailers should start by deciding where they add value.
- Partner vs build: Most retailers will need partners for refurbishment, authentication, and logistics, at least initially.
- Design for resale: Product teams should consider durability, repairability and materials that age well, because circularity starts at design.
- Data and item identity: Serialisation, digital product passports, or robust item-level tracking can reduce fraud and make grading faster over time.
A useful mental model is to treat resale as an “inbound supply chain” that needs the same discipline as traditional buying — with clear SLAs, cost-to-serve targets and a plan for scaling.
2) Sales: protect first-hand while growing lifetime value
Retailers worry, understandably, about cannibalisation. The better way to frame the opportunity is customer lifetime value and share of wardrobe.
- Trade-in as a demand lever: Credit-based trade-in can bring customers back more often and smooth conversion during cautious spending cycles.
- Segmented participation: Not every category needs resale. Start where value retention is strongest and operational complexity is manageable. Prioritising sub-category depth over breadth can help increase the pace of stock sell-through which gets the resale flywheel motoring.
- Pricing architecture: First-hand and resale pricing should be designed together, so the brand controls value perception rather than leaving it entirely to the market.
If resale is positioned as an “entry point” for new customers and a “retention loop” for existing ones, it can support both acquisition and repeat purchase, even if the first transaction is second-hand.
3) Marketing: move from sustainability claims to life-enhancing experiences
Resale marketing works when it focuses on the customer’s lived benefits: saving money, finding unique pieces, decluttering, and shopping in a more conscious way.
- Make it fun: Lean into discovery, drops, “treasure hunt” merchandising and creator-led storytelling.
- Make it easy: Promote how simple it is to trade in or list – because sellers and supply are crucial to the flywheel.
- Make it credible: Use clear impact metrics where possible, but avoid vague virtue signalling. Resale’s advantage is that it’s tangible.
Retailers should also expect resale to influence brand perception even outside circular initiatives. When Vinted can outrank many first-hand retailers by customer numbers, the “default” shopping mindset is changing.
The takeaway
Resale is no longer an alternative channel. It’s a new layer of competition – and a new set of customer expectations for digital fashion retail.
Retailers don’t need to abandon first-hand to win in this world. But they do need to revisit the fundamentals: how they operate, how they drive sales, and how they market value. In the next phase of ecommerce, the most resilient brands won’t just sell products, they’ll build ecosystems where items (and customers) keep coming back.
