Why we overpay for clothes: overproduction, surplus stock and retail markups explained
Every year, the global fashion industry produces far more clothing than the world actually buys. What happens to the leftovers — and why shoppers keep paying full price while perfectly good surplus sits in warehouses — says a great deal about how retail pricing really works.
Walk into almost any high-street shop and the price on the tag feels fixed, almost natural. In reality it's the end point of a long chain of decisions: how much to manufacture, how much to hold back as a buffer, how to price for a target sell-through, and how to cover the considerable overhead of running physical and online retail. Overproduction sits quietly at the centre of that chain — and it shapes prices far more than most people realise.
The scale of overproduction
Estimates vary, but industry analysts commonly put annual global garment production somewhere in the range of 80 to 150 billion items. Brands rarely plan to sell every unit. To avoid stock-outs of popular sizes and to hit shipping deadlines across dozens of markets, most produce a deliberate buffer above forecast demand. Widely cited figures suggest that a meaningful share of what's made — often quoted in the region of 20 to 40 percent depending on the category — never sells at full price, and some never sells at all.
The unsold remainder has a name in the trade: deadstock. It is brand-new, undamaged, on-trend-enough merchandise whose only "flaw" is that it arrived in greater quantity than the market wanted, or lingered one season too long.
What actually happens to unsold inventory
Holding stock is not free. Warehousing carries rent, handling, insurance and — crucially — the cost of capital tied up in goods that aren't earning anything. As inventory ages, the maths turns against keeping it: the storage bill can quietly exceed what the items would ever recover on a markdown rail.
Faced with that, distributors and brands typically choose one of a few routes:
- Progressive discounting — sale rails and outlet channels that trim the price until the stock moves.
- Bulk liquidation — selling surplus in large lots, sometimes priced by weight or by pallet, to clearance and off-price buyers.
- Disposal — in the least defensible cases, unsold goods have historically been destroyed or landfilled to protect price positioning.
The economic logic is blunt: once storing a garment costs more than it can realistically fetch, the rational move is to clear it out quickly, even at a fraction of its original ticket.
The everyday shopper effectively subsidises the overproduction buffer — paying retail inflation while warehouses quietly clear out perfectly good surplus at a fraction of the price.
How the retail price is really built
A common rule of thumb in apparel is "keystone" pricing — roughly doubling the wholesale cost — though many segments layer on considerably more. The figure on the tag has to absorb a long list of costs that have little to do with the garment itself:
- manufacturing, materials and freight;
- store rent, staffing and fit-out, or warehousing and last-mile delivery online;
- marketing, discounting and the cost of processing returns;
- and the margin the business needs to stay solvent.
In other words, the retail price reflects the retail model as much as the product. Two identical items can carry very different tickets depending on which channel they travel through.
Why surplus costs so much less for the same item
This is the quiet insight behind clearance and off-price retail. When surplus is sold in bulk, much of that retail overhead never gets applied. Liquidation buyers acquire stock cheaply precisely because they take volume, take it "as is", and bypass the full-price storefront apparatus. The item in the box is often identical to the one on the boutique rail; what you're not paying for is the shop window, the advertising campaign and the months of shelf space.
The consumer angle: paying "retail inflation" on top of surplus
Put the pieces together and a paradox emerges. Households pay full price — a price inflated to fund overproduction, unsold-stock risk and the retail machine — at the very same time that enormous volumes of new, unworn surplus exist and are being cleared cheaply elsewhere. The "complaint", if there is one, isn't that clothes are expensive to make. It's that the standard retail system passes the cost of its own inefficiency to the shopper.
The waste dimension
There is an environmental cost to all this excess too. Estimates frequently cited by sustainability researchers put global textile waste at roughly 92 million tonnes a year. Every garment that is produced, shipped, and then never worn carries the full footprint of its making with none of the use. Channels that move surplus into people's wardrobes instead of into landfill are, at least on this measure, the more circular outcome.
The takeaway
Overproduction is not a scandal so much as a structural feature of how modern fashion is planned and sold. It guarantees a steady flow of brand-new surplus leaving the retail system — and it means the premium you avoid when you buy cleared stock is mostly the cost of the retail apparatus, not the quality of the clothing. Understanding that gap is the first step to being a more deliberate shopper.
