Saint Laurent Authentication
Expert Saint Laurent authentication with certified results.
How we authenticate Saint Laurent
Our experts verify every detail against known authentic Saint Laurent specifications. Here are the key checkpoints we examine.
Serial number format
YSL bags have a serial number on a white fabric tag or leather tab. We verify the number format, font, and tag material against known production standards.
YSL logo hardware
The interlocking YSL logo on clasps and hardware must have correct proportions, letter shapes, and a specific finish quality.
Chevron quilting
On quilted models, the V-shaped chevron pattern must align symmetrically with consistent stitch depth and spacing.
Interior stamps
The 'Saint Laurent Paris' or 'Yves Saint Laurent' stamp must show correct font, 'Made in Italy' text, and proper embossing depth.
Dust bag & packaging
We verify dust bag material, logo print, drawstring quality, and overall packaging against authentic standards for the production period.
