The Saint Laurent models to know

On the secondary market, the value of a Saint Laurent bag is decided first by the reference. Here are the lines our experts see most often — and those that resell best.

• Sac de Jour (2013) — The epitome of structured Parisian elegance.
• Loulou (2017) — The signature Y-quilting, with a rock spirit.
• Kate (2014) — Chain pouch, glamorous and sophisticated.

The pre-owned Saint Laurent market

Collectible leather goods remain the most liquid segment of the secondary market: rare models and neutral colours resell within days, while seasonal editions call for more patience.

How we authenticate a Saint Laurent piece

Every piece that joins Monogram Paris follows the same protocol in our Paris workshops: no catalogue photography, no supplier imagery, only shots of the actual item.

• Saddle stitching: regularity, angle and tension of the waxed linen thread
• Heat stamp: depth, typeface and placement consistent with the archives
• Hardware weighed and examined under a loupe (crisp engraving, original plating)
• Zip, pull, lining and feet: original parts, or replacements disclosed
• Entrupy analysis followed by a second expert review before listing

Care and storage

• Keep the piece stuffed inside its dustbag, away from direct light
• Avoid water, perfume and light leathers against new denim
• Feed the leather once or twice a year with a balm suited to the hide
