A counterfeiter can copy a logo, a shape, and a color, but stitching density is a manufacturing discipline, and it shows in every close-up photo. Authentic luxury handbags run seven to twelve stitches per inch, with Chanel typically at ten to twelve, and the count is even across the whole bag. The fakes give themselves away in the uneven spacing, the loose thread at a corner, and the skipped stitch where the machine turned, all of which survive even a mediocre listing photo if you know where to look.
The places to check are the same on every bag: the handle attachments, the flap edge, and the interior pocket seams, where the factory rushes and the stitching loosens first. Edge paint is the companion tell, since authentic edge paint is smooth and even while fake edge paint is often lumpy, cracked, or peeling. Authentication services such as Entrupy use microscopic imaging to compare stitching and materials against a database of authentic bags, and stitching is one of the first things their system checks, because it is hard to fake well and easy to photograph badly.
Hardware is the second check, and it starts with weight. A clasp or chain on an authentic bag is cast from solid brass or a zinc alloy and plated, so it feels heavy and cool in the hand, while counterfeit hardware is often hollow or made from a lighter alloy. The engraving should be crisp, evenly deep, and correctly spelled, and the font should match the house's standard, since fakes frequently get the lettering slightly wrong. Zippers should be stamped with the right brand name and move smoothly, and screws should be flathead in the places the authentic bag uses flatheads, not Phillips.
Leather is the third check, and it is the one that needs a nose as much as eyes. Authentic leather has a natural grain that varies slightly across the hide, a supple feel, and a faint leather smell, while fake leather is often stiff, plasticky, and uniform, with a chemical smell that gives it away before you look closely. The lining matters too: authentic linings are fitted cleanly with no bunching, and the stitching on the lining is as even as the stitching outside. A bag that smells like a factory and feels like plastic is a bag that was made in a factory, not a workshop.
The listing carries half the verdict before the bag is ever in hand. Price is the first clue: a bag listed far below its established resale value is not a bargain, it is a fake, and the resale market for luxury bags is transparent enough that the right price is easy to check. Photos are the second: stock photos lifted from a brand website, no photo of the date code or serial number, and no close-up of the stitching or hardware all say the seller does not want the bag examined.
The seller's history is the third clue, and the most reliable. A seller with twenty different luxury brands, all new with tags, all priced below market, is not a collector clearing a closet. Check how long the account has existed, how many sales it has made, and whether the reviews read like real buyers or like a script. The date code and serial number are the last check: the font, the format, and the placement should match the house's standard for that year, and a code that does not match the bag's era is a fake by itself.

Count the stitches along one inch of a straight seam and compare it with another inch on the other side: authentic bags run seven to twelve stitches per inch, evenly. Check the hardware engraving, the edge paint, and whether the seller shows the date code and serial number. Stock photos and no close-ups are themselves a warning.
Heavy and cool, cast from solid brass or a zinc alloy and plated. Fake hardware is often hollow or light, with shallow or misspelled engraving, wrong zipper brands, and Phillips screws where the authentic bag uses flatheads.
Real leather has a natural grain that varies across the hide, a supple feel, and a faint leather smell. Fake leather is often stiff, plasticky, and uniform, with a chemical smell, and the lining on a fake is frequently bunched or unevenly stitched.
A price far below the resale value for the model, combined with stock photos and no image of the date code or serial number. A seller listing twenty different luxury brands, all new with tags, is a second red flag that usually settles it.
