Hermès Kelly 25 · London

The Kelly 25 is the hardest working small bag Hermès makes and, in London, the one that most rarely reaches a shop floor. It has overtaken the 28 as the size clients ask for, and the combination of that demand with a bag the house has never made in quantity is why it seldom sits anywhere for long.

It holds less than a Birkin 25 and that surprises people. The flap, the touret and the tapered body all take volume, so where a Birkin 25 swallows a slim pouch, a Kelly 25 wants a phone, a card case, a lipstick and a folded scarf. What it gives back is the shoulder strap, which is the whole point: a Birkin cannot be worn hands-free and a Kelly can.

Sellier and Retourne divide this size more sharply than any other. A Kelly 25 Sellier stands upright with knife corners, almost always in Epsom or Box, and reads as formal — it is the version most people picture and the one most requested. A Kelly 25 Retourne rounds and softens, sits closer to the body and is markedly easier to live with day to day. Two bags, one name.

Leather follows construction. Epsom holds a Sellier crisp for decades and is the safest choice at this size. Box calf gives the deep, glassy surface collectors chase and shows rain. Togo and Clémence belong to a Retourne. Chèvre, fine-grained with a low sheen, suits the 25 particularly and is uncommon enough to be worth taking when it appears. Swift carries the most saturated colour of all.

Hardware is read closely at this scale. The touret, the plaque and the strap fittings sit within a small frame, so palladium and gold change the whole register of the bag rather than accenting it. On a black Sellier 25 the choice is effectively between an architectural object and a classical one.

The buying difficulty is specific and worth stating. Nobody walks into a boutique and buys a Kelly 25 Sellier in a chosen colour with chosen hardware; that combination is offered to very few people. Working with a specialist inverts the process — the specification comes first and the search follows — and it is the route most owners of a specific Kelly 25 actually took.

On value the 25 sits at the top of the Kelly sizes and has held there steadily, with Sellier in classic colours ahead of Retourne. As always this describes the market as we see it rather than predicting it, and a rare leather in the 28 will outrun a common one in the 25.

Every Kelly 25 at JULL is inspected by hand in our London workroom — stamp, hardware engraving and plating, the alignment of strap and touret, stitching, corners, feet and interior — and described as it is. Pieces are new, unworn and pre-owned, sourced through European boutiques below boutique retail where the market allows. Shown by appointment in London, filmed in detail for clients elsewhere, delivered insured across the UK.
