How to check a designer handbag
Leather, canvas, stitching, hardware, heat stamps and codes: a practical checklist for designer bags, with brand notes for Chanel, Louis Vuitton, Hermès and Gucci.
In short
- Designer handbags are among the most counterfeited items in fashion, and the better fakes are now made with real leather and heavy hardware.
- Smell can help too: new genuine leather smells of leather, while many fakes smell of glue or plastic.
- Luxury workshops are known for consistent stitching.
Why bags are worth checking
Designer handbags are among the most counterfeited items in fashion, and the better fakes are now made with real leather and heavy hardware. No single detail settles the question, so work through the whole bag and look for details that agree with each other.
Materials
Smell can help too: new genuine leather smells of leather, while many fakes smell of glue or plastic.
Stitching
Luxury workshops are known for consistent stitching. Look along the handles, the base corners and around patches, where fakes most often go wrong.

Hardware and heat stamps

Codes, chips and cards
Most brands mark their bags, but the system changes over time, so check what is right for the year the bag was made.

- Many Louis Vuitton bags from the early 1980s onwards carry a date code, a short series of letters and numbers stamped inside; newer bags, from around 2021, use an embedded chip instead
- Chanel used a serial sticker with a matching authenticity card for many years, and moved to a different system on newer bags
- Gucci bags usually carry a serial number on a leather tag inside
- Hermès uses blind stamps that include a year letter, alongside the brand's own stamps
Brand notes
- Chanel: the quilting lines should meet neatly across seams and pockets, and the interlocking CC should be even, with both Cs the same size
- Louis Vuitton: the monogram is symmetrical and placed with care; on some models made from one piece of canvas, the pattern runs upside down on the back, which is correct
- Hermès: saddle stitching done by hand looks slightly slanted and very regular; a perfectly machine-like seam on a model that should be hand-stitched is a warning sign
- Gucci: the GG pattern should line up at seams and be centred on the bag's panels
Photos to take for a check
