The label and serial number
Saint Laurent bags generally feature an interior leather label engraved with "YSL" or "Saint Laurent Paris" depending on the era, accompanied by an approximately six-digit reference number. The brand's name has changed several times since 2012, which helps to approximate the manufacturing period.
The details that make the difference
The quality of the logo engraving, the regularity of the stitching, the weight and grain of the leather, as well as the finish of the zipper (often a recognizable brand like Lampo or Riri) are reliable indicators for distinguishing an authentic piece.
Why combine multiple checks
No single element is sufficient to guarantee the authenticity of a piece of this value. It is the combination of several clues, examined by an expert eye, that allows for reliable verification.
