Short answer

Do not send money for a bag sold as a "fake Hermes Gaillac 38." The name combines a Hermes color with a size the house does not produce in the Birkin or the Kelly, so the listing cannot describe a real item and often does not describe what arrives either. If you want a bag you can carry, insure, or resell, buy a genuine pre-owned piece from a seller who documents provenance, or buy an unbranded bag from a maker you can name. If you want to understand the market, the sections below cover what these listings promise, what the true dimension bands are, and where buyers take losses.

What the listing actually offers

Gaillac is a color name Hermes has used on some leathers, a deep wine-toned shade. It is not a model, and it is not a factory code. Sellers attach it to a number to make an invented product sound catalogued. In the Birkin line the standard sizes are 25, 30, 35, and 40. In the Kelly line they are 25, 28, 32, 35, and 40. A 38 sits between two real Kelly sizes, which is why the title reads well to a search engine and badly to anyone who knows the brand. When a seller pairs a real color with an impossible size, the rest of the product page is usually invented as well, from the leather name to the hardware finish.

What to look for before you pay anything

Whether you are shopping pre-owned or evaluating a listing, the same checks apply.

  • Blind stamp: a genuine bag carries a small heat stamp with the maker mark, and a date and artisan code placed on a strap or interior tab, not on a hangtag.
  • Saddle stitching: Hermes uses two-needle hand stitching on stress points. Look for a slight angle and irregular spacing that a machine cannot repeat.
  • Hardware: weight, plating depth, and the shape of the turnlock. Real hardware feels dense and cool, and the engraving is crisp at magnification.
  • Leather behavior: Togo and Clemence show a fine natural grain that creases rather than cracks. Epsom holds a pressed, even grain.
  • Documentation: receipts, boutique records, and third-party authentication letters with the authenticator named and reachable.
  • Seller identity: a business name, a return address, and a return window in writing.

Real spec bands to check against

  • Birkin: 25 cm, 30 cm, 35 cm, 40 cm. Width grows in even steps, and the handle drop stays close to 10 cm.
  • Kelly: 25 cm, 28 cm, 32 cm, 35 cm, 40 cm, sold with a shoulder strap on most sizes.
  • Constance: 18 cm and 24 cm.
  • Stitch density on a genuine bag runs roughly 9 to 11 stitches per inch along visible seams.
  • Date coding has run through single letters and symbols inside a shape, changing with the production year.

Any listing that quotes a 38 cm Birkin or Kelly, or that measures a bag at 38 cm and calls it standard, is describing a product the house does not make.

Pitfalls that cost buyers money

  1. Tier language. Words like mirror, 1:1, or factory direct are marketing labels, not quality grades, and no standard backs them.
  2. Stolen photos. Reverse image search the pictures. Catalog images lifted from a boutique or a resale platform are the most common bait.
  3. Payment outside protection. Wire transfers, gift cards, and crypto leave you with no chargeback path.
  4. Customs risk. Counterfeit goods imported into the United States can be seized and destroyed, and you are the importer of record.
  5. No resale value. A counterfeit carries no resale market, no insurance coverage, and no repair path from the brand.
  6. Fake authentication. A certificate from a service with no name, no address, and no phone number proves nothing.

FAQ

Is there a real Hermes Gaillac 38?

No. Gaillac appears as a leather color on some Hermes items, and 38 is not a standard Birkin or Kelly size. The combination is a search term, not a product.

What size should I look for instead?

If you want a Kelly near that measurement, look at the 35 or the 40. For a Birkin, look at the 30 or the 35. Check the width across the base with the bag closed, since sellers measure different points.

Is buying a counterfeit illegal?

US law treats trademark counterfeiting as a civil and criminal matter. Sellers face liability, and buyers face seizure of the goods at import, plus no legal recourse when the item never arrives or arrives damaged.

Do counterfeits ever use real leather?

Some use decent leather. That does not matter for value. What you are buying in a real bag is provenance, craft, and a service relationship, and none of those transfer to a copy.

How do I verify a pre-owned bag?

Use a paid authentication service that inspects hardware, stamp, stitching, and leather in hand or in high-resolution images, and confirm the seller accepts returns long enough for that review to finish.
