My father counted threads through a brass loupe. He sold wool by the meter and he did not trust his eye, so he trusted ten times magnification and a steady hand, and that same instrument, the jeweler's loupe, is still what a handbag authenticator raises to a seam before she tells you whether to spend 4,000 euros. For a long time the loupe won. You turned the bag inside out, you read the lining and the stitch count and the way the hardware was set, and the fake told on itself in a second.
That trick is failing, and it is worth being precise about why. In a January client advisory on dupes and super-fakes, the law firm White & Case describes a counterfeit that no longer guesses at the original. It is reverse-engineered from it, priced between $500 and $5,000, not the few dollars of a street dupe. The methods are industrial now: 3D scanning, CNC machining, and AI that reads the genuine article and reproduces it. The forger is no longer a bad tailor. He is a good scanner. When the interior is copied from a scan of the real interior, turning the bag inside out shows you the same seam either way.
So the response has split in two, and neither half is a loupe. One half is forensic. Entrupy, the New York authentication company, now reads fabric, stitching, and metal through a microscope attachment across millions of data points, and its State of the Fake 2026 report, covering 2025, puts numbers to the problem: $3.7 billion of goods run past its system, and 8.1 percent of luxury items were flagged as unidentified, meaning its system could not confirm them as genuine. Apparel was worse still, close to one item in three it could not confirm. By that same could-not-confirm measure, and only among the bags sent to Entrupy, the highest share was for items labeled Goyard at 18.9 percent and Prada next at 13.1, meaning that fraction of the ones submitted could not be verified as genuine, not that so many bags carrying those names are fake. Goyard made up only about one percent of submissions, so these are shares of what reached the scanner, not of every bag in the world. Louis Vuitton was by far the most frequently submitted. "The speed of the counterfeit cycle," the company's chief executive Vidyuth Srinivasan wrote, "has created even more distrust." The machine that made the fake convincing is the same machine you now need to catch it.
The other half is legal, and here the map is jagged in a way most shoppers never notice until customs stops them. There is no EU-wide definition of a dupe, so each country judges for itself. In Spain and Italy, White & Case notes, even privately buying and owning a super-fake can be an offense punishable by a fine. In Germany, customs can seize the thing, but merely owning it generally costs the buyer nothing. The buyer's exposure, in other words, is geographic. In Palma de Mallorca, according to local news reporting, a civic ordinance is said to let the city fine buyers, not just sellers, with buyer penalties reported at up to 750 euros for purchasing from a street vendor. Reported figures for Italy and Spain run much higher and vary wildly by source, so treat the round numbers with suspicion; the direction of travel is not in doubt. The European Commission and EUIPO, in their joint customs enforcement figures, put the haul at 152 million fake articles detained in the EU in 2023, up 77 percent in a year.
Autumn is when the expensive coats and bags move, and it is worth saying the plain thing. The loupe did not lie to you. It was simply pointed at a copy that had already read the original. What it cannot tell you, and what a scanner and a lawyer now have to, is where you are standing when you carry the thing home.
