The Kelly is easy to reduce to one silhouette, but the line runs from a coin-purse-sized Mini through a genuine travel bag, in two distinct constructions, and into half a dozen spin-off styles that barely resemble the original top-handle shape. This guide maps the whole family so you know what you are actually looking at — and how hard each version is to find.
The Kelly Size Ladder
Like the Birkin, the number in a Kelly's name refers to its approximate width in centimetres. Because the Kelly is a more structured, narrower-profile bag than the Birkin, its depth runs proportionally slimmer at every size.
| Size | Approx. Dimensions | What It Fits / Character | Sourcing Difficulty |
|---|---|---|---|
| Mini Kelly (Kelly 20) | ≈ 20 × 14 × 7 cm | Card holder, lipstick, phone at a squeeze — an accessory as much as a bag | Very hard — thin production, high demand |
| Kelly 25 | ≈ 25 × 19 × 9 cm | Compact daily size; narrower depth than a Birkin 25 due to the structured silhouette | Hard — the size the current market wants most |
| Kelly 28 | ≈ 28 × 22 × 10 cm | The classic all-rounder; the size most associated with the original 1950s design | Moderate to hard |
| Kelly 32 | ≈ 32 × 23 × 12 cm | The value entry to the Kelly line; broader supply than the smaller sizes | Moderate |
| Kelly 35 | ≈ 35 × 25 × 13 cm | A practical everyday-to-work size, closer to a structured tote | Moderate |
| Kelly 40 (Kelly Lakis) | ≈ 40 × 30 × 15 cm | Travel-oriented; a genuinely large, niche-market size | Low demand keeps it easier to find |
The 25 leads current demand for the same reasons the Birkin 25 leads its own range — fashion has moved smaller, and boutique output has not caught up. Full pricing by configuration is in our Kelly 25 price guide.
Sellier vs Retourne: The Kelly's Own Variable
Every Kelly, regardless of size, is built in one of two constructions, and the difference goes well beyond appearance.
Sellier
Stitched with the seam allowance turned outward, so the stitching sits visible on the exterior edge. This produces sharp, rigid edges and a formal, structured silhouette. It requires a leather that holds a crisp line — Epsom and Box are the classic choices — and the tight, precise external stitching is genuinely harder to produce, which keeps supply thinner and prices higher.
Retourne
Sewn inside-out and then turned right-side-out, hiding the seam inside the bag. The result is softer edges, a more relaxed silhouette, and a bag that suits softer, more pliable leathers like Togo or Clemence. Retourne construction is more forgiving in daily use and more common on the pre-owned market, which keeps it priced a step below equivalent Sellier pieces.
The distinction changes durability as much as looks: Sellier corners show wear first and are the most expensive kind of damage to restore, while Retourne is more resilient to the small knocks of everyday carry. It is the same lever the Kelly 25 price guide uses to explain price bands, and it applies at every size in this ladder.
Beyond the Bag: Danse, Pochette, Cut, To Go & Depeches
The Kelly's turn-lock closure and silhouette language have been reworked into several standalone pieces that share the name but not the shape of the original top-handle bag.
Kelly Danse
A crossbody flap bag that borrows the Kelly turn-lock but abandons the structured top-handle shape entirely, worn on a long strap. It reads as the casual, off-duty member of the family — smaller, softer, and designed for hands-free daily wear.
Kelly Pochette
A small clutch companion, often carried on its own wrist strap or slipped inside a full-size Kelly as an organiser. Many buyers acquire one specifically to pair with a Kelly bag they already own.
Kelly Cut
A flat clutch with the Kelly turn-lock mounted along the top edge and no handle at all — a genuine style statement rather than a practical everyday bag, and consistently one of the harder Kelly-family pieces to find.
Kelly To Go (K2G)
A card holder or compact wallet on a chain — the smallest piece in the family, and treated by the market more as a leather good than as a handbag.
Kelly Depeches
A structured document holder or slim briefcase carrying the Kelly lock, unisex in styling and leaning office-appropriate rather than fashion-forward. It draws a smaller, more specific collector base than the bag proper.
What's Hardest to Source
Sourcing difficulty does not track cleanly with price. Some of the rarest pieces to find are small leather goods, not full bags, because Hermès produces them in far smaller runs relative to demand.
| Variant | Character | Sourcing Note |
|---|---|---|
| Kelly Danse | Crossbody flap bag using the Kelly turn-lock; worn on a long strap, casual register | Moderate — more accessible than a full-size Kelly |
| Kelly Pochette | Small companion clutch, wrist strap or none; often bought alongside a full Kelly | Moderate to hard |
| Kelly Cut | Flat clutch silhouette with the Kelly lock on top, no handle; wrist strap optional | Hard — a genuine style statement, thin supply |
| Kelly To Go (K2G) | Card holder / wallet on a chain, smallest of the family | Easier — treated more as a leather good than a bag |
| Kelly Depeches | Structured document holder / briefcase with the Kelly lock; unisex, office-leaning | Easier — smaller collector base |
In broad terms: the Kelly 25 and 28 in Sellier construction with gold hardware in a neutral colour is the hardest full-size configuration to find, the Kelly Cut is the hardest standalone piece, and the smaller leather goods (To Go, Depeches) are comparatively the easiest entry point into the Kelly world. Whatever the piece, the counterfeiting risk scales with desirability — insist on independent authentication before money moves.
