Short answer
A genuine vintage Hermès pocket square has a hand-rolled, hand-stitched hem, a print that sits inside the silk rather than on top of it, and a correctly dated copyright mark next to the Hermès Paris signature. Most fakes fail on the hem first. Machine stitching, a flat pressed edge, or a hem that curls in one direction are the fastest tells. No single detail proves authenticity on its own, so check at least four markers before you decide.
What counts as a vintage Hermès pocket
Collectors use "pocket" for the small formats: the gavroche and pochette at roughly 45 cm square, plus the classic 90 cm carré that people fold into a pocket. Vintage means pre-2000s production for most sellers, though the term gets stretched. Older pieces may have no care tag at all, which is normal and not a sign of a fake.
Before you start
- A tape measure and a 10x loupe
- Daylight or a bright neutral lamp
- Reference photos of the exact colorway from auction archives
- A return window you can still use
How to check the piece
- Lay the square flat on a white surface and photograph it in daylight so you have a record of what you received.
- Measure the sides. Small formats run near 45 cm and the carré near 90 cm. Slight shrinkage from washing is normal, but a 42 cm square sold as a gavroche is a warning.
- Turn the square over and look at the hem from the back. Hand rolling leaves small visible stitches on both faces and a rounded, slightly uneven edge.
- Run a fingernail along the hem. A hand-rolled edge stays soft. A glued or machine-pressed edge feels like a thin ridge or crushes flat.
- Hold the silk to the light. Real silk twill shows an even weave with no bright plastic sheen and no white core where the ink stops.
- Check the signature area with the loupe. Look for the Hermès Paris mark, the copyright symbol, and a year that matches the design's release window.
- Inspect the print edges at 10x. Genuine scarves show fine dot or line detail with soft transitions. Fakes show pixel steps, muddy outlines, or color that bleeds past the design line.
- Weigh the drape in your hand. Silk twill of this weight folds with a crisp body and springs back. Polyester slumps and holds a crease.
- Compare the colorway against archive photos. If the color combination does not appear in any catalog or auction record, treat the piece as suspect.
- Smell the fabric. A sharp chemical or ink odor points to a recent print run, not a decades-old scarf.
Red flags
- An evenly spaced machine stitch along the entire hem
- A hem that lies dead flat with a hard crease
- Misspelled or poorly spaced Hermès Paris lettering
- A copyright year that postdates the seller's claimed production date
- Print that cracks or flakes when you flex the silk
- Tags sewn on with a straight machine stitch in bright white thread
What fakes get right
The best copies nail the artwork and the box. They get the hem, the silk weight, and the print depth wrong. That is why you check the construction first and the design second. A convincing print on a bad hem is still a fake.
Getting a firm answer
If the piece is expensive, pay for a specialist authentication or send it to a house that handles silk accessories. A written opinion with the reasoning spelled out protects you if the seller pushes back. Photograph the hem, the signature, and the print edges at high magnification before you ship anything out.
