Counterfeit fashion: how to actually verify what you bought
How can I tell if the clothing or accessory I bought is authentic?
You usually cannot tell from the item itself. Modern counterfeits reproduce stitching, labels, serial numbers, holograms and packaging closely enough that even experienced buyers are wrong. What a counterfeit seller cannot reproduce is a documented supply chain: an invoice from an authorised wholesaler, proof of authorised distribution, and consistent paperwork linking that specific item to a legitimate source. Asking the seller for that evidence is a far more reliable test than examining the product.

Why visual checks stopped working
For years, guides taught buyers to look for crooked stitching, misaligned logos or cheap hardware. That advice made sense when counterfeits were crude. It no longer describes the market. So-called super-fakes are produced in the same industrial regions, sometimes on comparable machinery, and reproduce the details those guides told people to check.
There is a second problem with visual checks: they are published. Every article explaining which stitch count to look for is also read by the people making the fakes, who correct exactly those tells in the next production run. Advice based on appearance has a short shelf life by construction.
This is why serious verification has moved upstream, to the question of where the goods came from.
What the numbers actually say
Counterfeit and pirated goods represent about 2.3% of world trade, worth an estimated 467 billion US dollars, according to the joint OECD and EUIPO study published in May 2025. That study covers 2021 data: it is the most recent global measurement available, not a description of today.
On the buyer side, EUIPO 2023 perception study surveyed 25,824 people across the European Union. It found that 15% had bought a counterfeit unintentionally, having been misled, rising to 23% among 15-24 year olds. More tellingly for anyone reading this page: 39% of Europeans have wondered whether something they bought was genuine, and 52% among the youngest group.

The four questions that actually discriminate
Can the seller produce a supplier invoice for this specific item? Legitimate resellers keep purchase records for accounting and warranty reasons. Being unable to produce one for an identified product is unusual and revealing.
Is the seller listed by the brand as an authorised retailer? Most brands publish their authorised distributor lists. Absence proves nothing on its own, because parallel imports are lawful in the European Union, but combined with silence it becomes meaningful.
Does the paperwork hold together? An invoice with a company number that does not match the registry, a VAT number that fails validation, or a trading address that does not exist are concrete, checkable inconsistencies.
Does the seller answer a documented request? This is the single most informative signal. A seller with nothing to hide replies. Persistent silence, after a reminder and a formal notice, is what separates a business defending its reputation from one that cannot.
The four checks, in order of usefulness
Ask for the supplier invoice
For that specific item. Legitimate resellers keep them for accounting and warranty reasons.
Check the company against the register
Does the company on the invoice exist, was it trading at that date, does its declared activity match?
Look for the brand's authorised list
Absence proves nothing on its own, parallel imports are lawful, but it is context.
Send a documented request and wait
Silence after a reminder and a formal notice is the most informative signal of all.
What to do if you suspect a counterfeit
Keep everything: the listing, the invoice, the packaging, the delivery note and all correspondence. Photograph the item as received, including labels and any codes, before wearing or altering it.
Contact the seller in writing and ask a precise question rather than making an accusation. Requesting proof of supply is a legitimate consumer request; alleging counterfeiting without evidence weakens your position and can expose you.
If you paid by card, note that chargeback windows are limited, commonly 120 days from the transaction depending on the scheme and issuer. Acting early preserves options that expire.
In the European Union, you also hold a statutory guarantee of conformity of at least two years under Directive (EU) 2019/771. A product that is not what it was described to be is a conformity issue, independently of any counterfeiting question.
What a buyer actually risks in France
Most pages on this subject still cite Article 414 of the French Customs Code. That article was repealed on 1 May 2026, when the Customs Code was entirely renumbered by Order 2026-265 of 8 April 2026. The provision in force is now Article L513-1, which sets three years imprisonment and a fine of twice the value of the goods.
There is no legal tolerance for personal use, and no quantity threshold below which possession becomes lawful. Customs state this plainly. In practice, an isolated traveller is usually dealt with through a customs settlement, which Article L613-2 describes as particularly intended for minor offences committed by travellers, and which always involves surrendering the goods.
Note one discrepancy worth knowing: the customs website still describes the fine as between one and two times the value, which reflects how penalties are modulated in practice, while the statute itself now sets twice the value.
On the intellectual property side, Article L716-10 of the French Intellectual Property Code remains in force and covers holding counterfeit goods without legitimate reason, punishable by three years imprisonment and a €300,000 fine. Its application to a private buyer turns on the notion of legitimate reason, which courts assess case by case.
Where an independent third party helps
A private buyer asking a seller for supply evidence is usually ignored. The same request from an identified third party, following a documented procedure with deadlines and a published outcome, is answered far more often. That asymmetry is the entire point of a verification service.
It is worth being clear about the limits. A documentary check establishes whether the supply chain can be demonstrated. It does not establish that an item is counterfeit, which requires physical examination and, in most cases, the brand's own expertise. The two approaches are complementary, and a serious service will tell you when the other one is the right route.
Questions fréquentes
Is buying from an unauthorised reseller illegal?
No. In the European Union, parallel imports of genuine goods placed on the market with the rightsholder's consent are lawful. An unauthorised reseller is not automatically a counterfeit seller, and treating them as such would be both unfair and legally wrong.
Can a serial number prove authenticity?
Not on its own. Serial numbers are reproduced on counterfeits, and the same number is sometimes duplicated across many items. What matters is whether that specific number can be linked to a documented purchase from a legitimate source.
Does a certificate of authenticity mean anything?
Only as much as its issuer. Certificates are among the easiest documents to forge, and many are issued by the seller themselves. A certificate from an independent party, or a traceable supplier invoice, carries far more weight.
What if the price was normal, not suspiciously low?
Price is a weak signal. Counterfeits are increasingly sold at or near market price precisely because a low price triggers suspicion. Conversely, genuine goods are often discounted through legitimate overstock channels.
Should I contact the brand directly?
It is worth trying, and some brands do authenticate items. Many, however, will not respond to individual consumers, or will only act if the item is sent in. That is why documentary verification through the seller is often the faster route.
