The 41% problem

Flip over the label on the shirt you're wearing. There's a decent chance it's wrong.

When Circle Economy scanned more than 10,000 discarded garments with near-infrared technology for a Dutch government-commissioned study, the composition labels were inaccurate enough to mislead a shopper in 41% of cases. Not fringe brands. Ordinary clothes from ordinary wardrobes.

That number isn't a fluke. In June 2026, EU market-surveillance authorities reported the results of a coordinated campaign across eight countries: of 132 garments tested, 37% were mislabelled, and authorities ordered 18 products withdrawn from sale.

Mislabelling sounds technical, but it's simple. The tag says one thing; the fabric is another. A "cotton" top padded with polyester. A "wool" scarf that's mostly acrylic. Sometimes it's sloppiness in a long supply chain. Sometimes the pattern looks deliberate: in the Dutch data, about a third of cotton-rich blends claimed far more cotton than they contained, and cotton is the fibre you pay extra for.

The uncomfortable part is enforcement. Fibre-content labels are legally required in the US under FTC textile rules and in the EU under the Textile Regulation, but the rules are weakly enforced. Spot checks like the EU campaign are rare, and 132 garments is a rounding error against what enters the market every week.

So what does "verified" mean, then? Real tools exist at industry level: isotopic analysis that fingerprints where a cotton crop was grown, pigment tracers read from a QR hangtag, even synthetic DNA embedded in the fibre itself. Brands pay for that testing; shoppers see the verified claim. Checking whether a garment carries one used to be homework, and now it takes a single scan in Lynen.

Regulation is slowly catching up too. Under EU Ecodesign rules in force since 2024, every garment sold in Europe is expected to need a scannable passport disclosing its fibre composition around 2027 or 2028. Until then, a tag is a claim, not a fact. Treat it like one.
