Pre-Owned Saint Laurent: The Buyer's Guide
By The Old Fashioned Club team
LouLou, Kate, College, Sac de Jour, Niki: the complete guide to buying a pre-owned Saint Laurent bag or jacket. Iconic models, leathers, authentication and resale value.

Buying a pre-owned Saint Laurent means treating yourself to Parisian elegance at its most rock'n'roll: the chevron quilting of the LouLou and the College, the discreet chic of the Kate, the structure of the Sac de Jour, and of course the couture legacy of the Le Smoking jacket. The second-hand market gives access to models and colourways withdrawn from the collections, often well below retail. This guide brings together models, leathers, authentication and resale value.
Yves Saint Laurent, Parisian elegance
Founded in 1961 by Yves Saint Laurent and Pierre Bergé, the house rewrote the twentieth-century women's wardrobe: Le Smoking in 1966, the safari jacket, the trouser suit, the Mondrian dress. This couture heritage still runs through the ready-to-wear today — the smoking jacket remains one of the most sought-after pieces on the second-hand market.
On the leather goods side, a turning point: in 2012, Hedi Slimane renamed the ready-to-wear line "Saint Laurent Paris" (the first name Yves disappeared from the clothing logo), while keeping "Yves Saint Laurent" on certain creations. Anthony Vaccarello has since extended this minimal yet sensual silhouette. Knowing these logos helps date a piece and spot an inconsistency.
The iconic bags to know
| Model | Distinctive feature | What to check |
|---|---|---|
| LouLou | "Y"-shaped chevron quilting, metal YSL monogram | Evenness of the chevron, fixing of the logo |
| College / Envelope | Quilting, leather-threaded chain, YSL flap | Condition of the chain, crispness of the quilting |
| Kate | Clean flap, monogram and tassel | Clean leather, clasp mechanism |
| Sac de Jour | Rigid structure, handles, padlock, architectural lines | How the structure holds, corners |
| Niki | Soft crinkled quilting, adjustable strap | Suppleness of the leather, condition of the strap |
The LouLou and the College, in chevron-quilted leather forming a "Y", are the contemporary best-sellers. The Kate embodies minimal evening chic with its tassel. The Sac de Jour, more structured and architectural, targets clients looking for a timeless work bag. The Niki, with its deliberately crinkled quilting, offers a more relaxed look.
The smoking jacket and ready-to-wear
Saint Laurent is more than its bags. The smoking jacket — the 1966 couture invention that dressed women in a sublimated masculine wardrobe — is one of the most coveted ready-to-wear pieces on the second-hand market. Look for a clean shoulder, an impeccable satin lapel and a tailored cut. The jackets, biker jackets and silk shirts of the Slimane/Vaccarello era are also highly sought-after.
For these pieces, check the composition and size labels, the quality of the linings and buttons, and the consistency of the logo ("Saint Laurent Paris" vs "Yves Saint Laurent") with the presumed year. Discover our pre-owned YSL jackets to get a sense of the pieces available.
How to authenticate a pre-owned Saint Laurent
Authentication starts with the logo and the era: "Yves Saint Laurent" or "Saint Laurent Paris" depending on the line and year — an inconsistency is a red flag. On bags, check the embossed interior stamp ("SAINT LAURENT / PARIS" or "YSL") and the quality of the stamping, along with the metal serial plate bearing a number and a model/season code, usually inside.
Examine the evenness of the chevron quilting (the Y motif should be crisp and symmetrical), the crispness of the interlocking YSL monogram, the quality of the stitching and the hardware. No single criterion is enough. At Old Fashioned Club, every Saint Laurent is expertly appraised and certified, and Entrupy authentication (AI + microscopy) is available on request.
Resale value and price ranges
Saint Laurent offers a good balance of prestige and accessibility on the second-hand market. As a guide, on the pre-owned market:
| Piece | Indicative pre-owned range |
|---|---|
| Small leather goods / wallet | €150 – €400 |
| Kate (depending on size) | €700 – €1,600 |
| LouLou / College (chevron quilting) | €800 – €2,000 |
| Sac de Jour (structured leather) | €1,200 – €2,500 |
| Smoking jacket / biker jacket (ready-to-wear) | €500 – €2,000+ |
These ranges depend on condition, size, material (smooth leather, grained, suede) and accessories (dust bag, card). Sought-after colourways and smoking jackets in pristine condition trade at the top of the range. These benchmarks are indicative only and shift with the market.
Why buy Saint Laurent second-hand
The second-hand market gives access to colourways and models withdrawn from the collections, and to the house's couture heritage — an archive smoking jacket, for example, unavailable in store. It is also a sustainable fashion choice and a way to enjoy YSL craftsmanship at a fair price. Buying from a reseller who authenticates and certifies every piece protects the buyer in a market where chevron quilting and the YSL monogram are widely copied.

Frequently asked questions
- What is the difference between Yves Saint Laurent and Saint Laurent Paris?
- In 2012, Hedi Slimane renamed the ready-to-wear line "Saint Laurent Paris", removing the first name Yves from the clothing logo, while "Yves Saint Laurent" remains on certain creations and the YSL monogram. This distinction helps date a piece and spot an authenticity inconsistency.
- What is the most iconic Saint Laurent bag?
- The LouLou and the College, in chevron-quilted leather forming a Y with the YSL monogram, are the contemporary best-sellers. The Kate (a clean tasselled flap), the Sac de Jour (structured) and the Niki (soft quilting) round out the most sought-after icons.
- How do you authenticate a Saint Laurent bag?
- Check the consistency of logo/era ("Yves Saint Laurent" vs "Saint Laurent Paris"), the embossed interior stamp, the metal serial plate with number and model code, the evenness of the Y-shaped chevron quilting and the crispness of the YSL monogram. Authentication should be multi-criteria and entrusted to an expert.
- Does the Saint Laurent smoking jacket hold its value second-hand?
- Yes. A 1966 couture invention, the smoking jacket is one of the most coveted ready-to-wear pieces on the second-hand market. Its value rests on condition (clean shoulder, impeccable satin lapel), cut and era. Archive models in pristine condition trade at the top of the range.
