The Kelly 25 is a compact, structured size best suited to evening use, special occasions, and as a considered second bag, while the Kelly 28 is the more practical everyday size, offering genuine capacity for daily essentials without losing the Kelly's signature silhouette. The 25 reads as jewellery for the arm; the 28 reads as a bag you can actually live with day to day.
In our sourcing work at Clutch, this is one of the most common questions we hear from clients across the GCC and Africa who are considering their first Kelly. Both sizes carry the same history, tracing back to the saddle-stitched Sac à dépêches that Hermès first produced in the 1930s, later renamed after Grace Kelly in the 1950s. The size decision comes down to how the bag will actually be used, not which one is "better."
What Is the Actual Size Difference Between the Kelly 25 and 28?
The Kelly 25 measures roughly 25cm in width, with a compact, boxy profile that sits close to the body. It holds a phone, a slim cardholder, keys, and perhaps a small pouch, but little else. It was designed with proportion in mind rather than utility, and it shows: the 25 is often described as the most jewellery-like size in the Kelly family.
The Kelly 28 measures roughly 28cm in width, and the extra few centimetres translate into a meaningfully deeper, wider interior. It comfortably fits a phone, wallet, sunglasses case, small water bottle, and a light cardigan or scarf. For clients who want one Kelly to serve as a genuine daily bag rather than an occasional accessory, the 28 is almost always the recommendation. The difference is not cosmetic; it changes what the bag can realistically do for you.
Which Size Is More Wearable Day to Day?
The Kelly 28 is the more wearable size for daily rotation. Its proportions sit naturally whether carried by the top handle, worn on the shoulder with a longer strap, or carried by hand into a meeting. It has enough presence to look considered without appearing precious, and enough room to function as your only bag for a full day out.
The Kelly 25 is wearable, but in a different register. It suits evenings, lunches, and situations where the bag itself is the statement rather than the workhorse. Clients who already own a larger everyday bag, such as a Birkin 30 or a Kelly 28, often add a Kelly 25 specifically for this purpose: a refined, occasion-led piece rather than a second daily bag. If you are choosing a single Kelly to wear most often, the 28 tends to serve better; if you are adding a second, more considered piece to an existing collection, the 25 earns its place.
Sellier or Retourne: Does Availability Differ by Size?
Yes, and this matters when deciding between the two sizes. The Sellier construction is rigid and structured, with visible external saddle stitching and a sharper, more architectural silhouette. It is closely associated with the Kelly 25, where the smaller proportions suit the crisper, more formal shape. The Sellier's precise lines are part of why the 25 photographs and wears like jewellery.
The Retourne construction is softer, with internal stitching and a slightly slouched, more relaxed body. It is more commonly found on the Kelly 28, where the softer structure allows the bag to expand and flex to hold daily contents comfortably. That said, both constructions do appear across both sizes depending on the leather and the season the bag was produced, so availability is never absolute. Clients with a strong preference for one construction should expect it to influence the leathers and colourways realistically available in their chosen size, and this is exactly the kind of nuance we work through during private sourcing.

Frequently Asked Questions
Is the Kelly 25 too small for everyday use?
It can work as an everyday bag if your daily carry is minimal, but most clients find it better suited to occasion wear or as a considered second bag alongside a larger piece.
Does the Kelly 28 come in exotic leathers?
Yes, the Kelly 28 is produced in exotic skins such as crocodile and lizard alongside classic leathers like Togo, Epsom, and Clemence, though availability of any specific leather and colourway varies and should be confirmed through private sourcing.
What drives the price difference between the two sizes?
Price is shaped by leather type, hardware finish (palladium or gold), colour rarity, condition, and whether the piece is Sellier or Retourne, rather than size alone. We recommend enquiring privately for an accurate quote based on the exact piece.
Can I request a specific size and construction combination?
Yes, this is the core of what private sourcing is for. Tell us your preferred size, construction, leather, and hardware, and we search discreetly on your behalf.
Which size holds its appeal better over time?
Both sizes are enduring, but the Kelly 28's daily practicality and the Kelly 25's jewellery-like rarity each appeal to different collectors, so the better choice depends on how you intend to use the bag rather than resale considerations alone.
Choosing between the two comes down to honesty about how you will actually use the bag. Browse our current Kelly 25 collection for the more compact, occasion-led silhouette, or the Kelly 28 collection if you want a Kelly that can carry your day.
