The Hermès Kelly Bag: Sellier, Retourne and How to Choose

Hermès began as a harness maker in Paris in 1837, and the Kelly's shape descends from a saddle bag the house made for riders. In the 1930s it became a women's handbag, the Sac à dépêches.

In 1956 Grace Kelly – that year married to Prince Rainier III and Princess of Monaco – was photographed holding the bag in front of her to shield her pregnancy from photographers. The image travelled around the world, clients began asking for "the Kelly bag", and Hermès officially adopted the name in 1977. For a boutique on Place du Casino, it is a story we never tire of telling.

Every Kelly is made in one of two constructions, and the difference changes the bag's whole character.

Neither is better; they are different bags. If you want the Kelly to look exactly as it did on the first day, choose Sellier. If you want a bag that becomes yours over time, choose Retourne.

Like the Birkin, the number is the width in centimetres. The common sizes are:

• Kelly Mini (20) – the most coveted Kelly of recent years, worn on its shoulder strap. Holds a phone and a cardholder.
• Kelly 25 – a refined everyday size with room for essentials; works by hand, on the arm or on the strap.
• Kelly 28 – the classic proportion and a favourite first Kelly. Fits a wallet, phone, keys and sunglasses comfortably.
• Kelly 32 – a generous day bag, often in Retourne, that fits a small tablet.
• Kelly 35 and 40 – larger, travel-friendly sizes, less common today and increasingly collectable.

Every Kelly comes with a detachable shoulder strap, which makes even the larger sizes practical.

Beyond the classic bag, Hermès has built a family around the Kelly's turn-lock and flap: the Kelly Pochette, a clutch with a small top handle; the Kelly Cut, a slim, elongated clutch; the Kelly Danse, which converts between belt bag, shoulder bag and crossbody; the Kelly To Go, a wallet on a strap; and the Kelly Elan, a slim shoulder bag. Each is collected in its own right and often easier to find than the classic sizes.

Kellys come in the same leathers as the Birkin – Togo, Epsom, Clemence, Swift, Box calf and exotics – and the leather choice interacts with the construction. A Sellier Kelly in Epsom or Box calf is crisp and structured; a Retourne Kelly in Togo or Clemence softens and slouches beautifully. For a full explanation of each leather, see our Birkin buying guide.

Neutrals such as Noir, Gold, Étoupe and Craie are the most liquid on the resale market; seasonal brights and exotics are rarer and command more for the right buyer.

• Stitching – even, slightly slanted saddle stitches. On a Sellier Kelly, look along the outer edges; on a Retourne, inside the seams.
• The turn-lock and padlock – clean engravings, smooth operation, and a lock number that matches the keys.
• Stamps – the Hermès Paris heat stamp below the flap, the year letter and artisan mark inside. See our authentication guide.
• Handle and corners – the first places wear shows, and the first places we photograph for clients.

Every Kelly on our Kelly page is checked by our specialists before it is listed. At the time of writing (November 2026), Kellys on Montévane range from $12,500 to $85,000 depending on size, leather and condition.
