Comparison: Real vs Fake YSL Niki

To spot a fake YSL Niki bag, carefully examine the label on the interior side of the bag. Fakes typically have inscriptions with improper font-weight and spacing between letters.

1. Interior label

Authentic Yves Saint Laurent Niki Bag:

• Stitching: Features thinner and slimmer threads on the label.
• “SAINT LAURENT PARIS” Inscription: Stamped less deeply into the leather, with thinner and wider letters.
• “MADE IN ITALY” Text: Stamped less deeply into the leather, thicker font weight, and clear legibility.

Fake Yves Saint Laurent Niki Bag:

• Stitching: Displays thicker and more massive threads on the label.
• “SAINT LAURENT PARIS” Inscription: Stamped too deeply into the leather, with thicker and narrower letters.
• “MADE IN ITALY” Text: Stamped too deeply into the leather, with a thinner font weight and less legibility.
