They are the two most famous bags in the world. Yet, those who are not familiar with the luxury market often confuse them or don't understand why they can be worth tens of thousands of euros. The truth is that the Kelly and the Birkin are not just bags: they are investments, cultural symbols, and some of the most refined handcrafted objects ever produced by humanity. In this guide, we explore the real differences between the two, their history, current prices in the vintage market, and how to understand which one is for you.
The Story: Different Stories, Same DNA
The Hermès Kelly was born in 1935 under the name Sac à dépêches, designed as a rigid bag for travel and documents. It took its current name in 1956 when Grace Kelly—recently Princess of Monaco—was photographed on the cover of Life using the bag to hide her baby bump in her fifth month of pregnancy. From that moment on, the Kelly's destiny was sealed: rigorous elegance, sculptural structure, association with aristocratic femininity.
The Birkin was born almost half a century later, in 1984, from a chance encounter on an airplane. Jane Birkin, a French-British singer and actress, found herself seated next to Jean-Louis Dumas, then Hermès' creative director. Jane complained about not being able to find a bag large enough for her daily needs. Dumas grabbed a pen and paper and sketched the design in his notebook. That sketch became the Birkin: larger, more casual, more structured but less formal than the Kelly. Two bag philosophies, the same level of artisanal perfection. (a valid alternative Coco Chanel)
Structural Differences
Understanding the physical differences between the Kelly and the Birkin is essential for choosing the right one and recognizing them in the vintage market.
The Kelly is traditionally carried with a single handle by hand or, for newer models, with a shoulder strap (bandoulière). It has a central clasp (the small fastener on the front) and four side straps. It comes in two construction versions: Sellier (external stitching, very rigid shape, sharp profile) and Retourné (internal stitching, softer and more rounded shape). The Kelly Sellier is the more formal and rigorous version, the one worn in Monte Carlo. The Kelly Retourné is more suitable for everyday use.
The Birkin has two handles that drop down the sides, four flaps closed by straps, and a cover with a zip lock. It is always made with external stitching, so technically its structure is equivalent to a Kelly Sellier. But its wider profile, two handles, and more open shape make it visually more informal, more suitable for daily use. There is no Retourné version of the Birkin.
Available Sizes
Both bags are available in different sizes, identified by a number indicating the width in centimeters.
The Kelly comes in sizes 20, 25, 28, 32 (the most classic), 35, and 40. Sizes 28 and 32 are the most common in the vintage market. The Kelly 20 (the Mini Kelly) has become very popular in recent years and is often harder to find.
The Birkin comes in sizes 25, 30 (the most popular), 35, and 40. The Birkin 30 is the perfect balance between capacity and portability. The Birkin 35 was Jane Birkin's favorite. There are also special versions like the HAC (Haut à Courroies, predecessor of the Birkin) in sizes 28, 32, 36, and 50. (sell your bag)
Prices in the Vintage Market 2026
The pre-owned Hermès market is one of the most solid in luxury: Hermès bags maintain and often exceed their original purchase value. In the vintage market, prices vary enormously based on material, size, color, condition, and year of production.
A Kelly in Togo or Clemence leather (the most common leathers) in size 28 or 32, in good condition, ranges from €6,000 to €12,000. A Kelly in exotic leathers (crocodile, ostrich, lizard) can exceed €25,000. The Kelly Mini Pochette version, used as a clutch, starts from €3,500-4,000. (see our installment payments)
A Birkin 30 in classic leather (Togo, Clemence, Epsom) starts from €7,000 and can reach €15,000 for rare colors or special editions. A Birkin 25—the most sought-after size in recent years—has similar or higher prices than the 30 in the same condition, due to its rarity. Birkins in exotic materials or in So Black or special versions can exceed €50,000.
💡 Both the Kelly and the Birkin have historically shown to appreciate in value over time: a study by Baghunter showed that the Birkin outperformed both gold and the stock market as an investment in the decade 2010-2020.
How to Choose: Kelly or Birkin?
The answer depends on your lifestyle and how you intend to use the bag. The Kelly is for those who want an icon of classic elegance, to wear for formal occasions or as a statement piece with a polished outfit. It's the right bag if you love structured style, if you like to carry the bag by hand, and if the context in which you'll use it is business or important occasions.
The Birkin is for those who want an icon with a more everyday character, capable of holding everything needed without sacrificing charm. It's the right bag if you have a more casual but always refined style, if you need space, if you want something that can go from an office to lunch with friends.
However, there is a third, more honest answer: don't choose based on an abstract style, but based on what you find available, in what condition, and at what price. In the vintage market, the choice is often driven by opportunity: an exceptional piece at a fair price is always worthwhile, regardless of the model.
How to Recognize an Authentic Hermès
The market for fake Hermès bags is thriving because demand is enormous and original supply is intentionally scarce. Learning to recognize an authentic piece is fundamental before any purchase.
The stitching on an authentic Hermès is hand-stitched using the saddle stitch technique with two needles: each stitch is handmade with two threads that cross, making the seams symmetrical, regular, and very strong. Count the stitches per centimeter: an authentic Hermès typically has 4-5 stitches per centimeter, very close together and perfectly regular.
The production stamp is hot-stamped inside the bag and bears the letter of the production year (a system Hermès has used since 1945), the artisan's number, and the Hermès Paris stamp. Fakes often imitate this stamp, but the quality of the engraving is different: the letters are thinner, less sharp.
The hardware (locks, screws, zippers) of an authentic Hermès is solid metal, heavy, and with an impeccable finish. The lock opens and closes with a precise click. Any authentic Hermès bag comes with the padlock and two keys, stored in a small leather pouch.
Finally, the leathers. Hermès uses some of the most precious leathers in the world: Togo (soft and durable grain), Clemence (similar to Togo but softer), Epsom (pressed grain, very rigid, scratch-resistant), Box Calf (smooth and shiny, the most classic), Chevre Mysore (goatskin, very light). Learning to recognize Hermès leathers is an art: if you have doubts, authentication by an expert is the only real guarantee. (see Hermès leathers)

Where to Buy an Authentic Vintage Hermès in Italy
The vintage Hermès market in Italy is still relatively young compared to Paris or London, which means there are fewer intermediaries, more competitive prices, and—if chosen well—real opportunities. The key is to always buy from specialized luxury resale retailers with a documented authentication process, not from private sellers on generic marketplaces where the risk of encountering fakes is high.
International platforms like Vestiaire Collective offer a wide selection but often with premium prices and an authentication process delegated to third parties. Specialized physical or online retailers in Italy often offer a more direct relationship, the possibility to see the item before purchase, and a human connection that makes a difference in luxury resale.
