The Hermès Kelly belt is £1,080 in the UK as of September 2026, comes in one width and one leather, is sized in centimetres from 65 to 105, and is not the same thing as the H belt — a confusion that sends a surprising number of people home with the wrong one. This guide explains what the Kelly belt is, how its sizing works and where to measure, how it differs from the reversible H belt with its separate buckle, which colours are permanent, and how to buy one in the UK — including through us, new with the boutique receipt at £865.
What the Kelly belt is
The Kelly belt takes the closure of the Kelly bag — the two straps, the turn-lock and the touret, the little post the straps sit over — and puts it on a narrow strap of Epsom calfskin, eighteen millimetres wide. The house calls it the Kelly 18 belt. The hardware is gold-plated or palladium-plated at the same price, the leather is Epsom in every colour, and the closure works exactly as it does on the bag: the straps go over the touret, the turn-lock turns, and the belt is closed.
It is worn differently from a jeans belt. Eighteen millimetres is too narrow for most trouser loops and the closure is too pretty to hide under a jumper, so the Kelly belt sits high — on the waist of a dress, over a knit, over a coat — where the hardware reads as jewellery. That is the whole idea and the reason it is priced as it is.
The Kelly Pocket 18 is the same belt with a small flap pouch fixed to the strap, big enough for a card and a key, at £1,680. Fewer people need it, but the ones who do are usually going somewhere without a bag.
Kelly belt or H belt
This is the question most people are really asking. The H belt is the other Hermès belt: a buckle in the shape of an H and a reversible strap — one leather on each side, usually black on one and Gold or Etoupe on the other — sold together at £825 in the classic 32 mm width, with the men's 38 mm at £925 and the Mini H at 24 mm at £705. The buckle comes off, so the strap can be turned over or replaced, and the belt can be worn two ways from day one.
The Kelly belt does none of that. There is no separate buckle, no reversible strap and no second colour; it is one piece of leather with the Kelly closure sewn on. What you gain is a closure that is unmistakably from the bag and a belt that works with dresses in a way the H does not. What you give up is the versatility of two sides and the ability to change the buckle later.

|---|---|---|
| Width | 18 mm | 24, 32 or 38 mm |
| Leather | Epsom, one colour | Two leathers, reversible |
| Closure | Kelly turn-lock and touret | H buckle, removable |
| Worn | High: dresses, knits, coats | Trousers, jeans, through loops |

If you wear belts through loops most days, the H belt is the better first purchase. If you wear dresses and want the hardware to show, the Kelly belt. Many people who own both wear the H on weekdays and the Kelly in the evening, which is the honest answer to the either-or.
How the sizing works
Hermès sizes belts in centimetres, and the number is the distance from the closure to the middle of the five holes. A size 75 sits at 75 centimetres on the middle hole, with two holes either side for a little adjustment. The Kelly belt runs from 65 to 105 in steps of five.
The mistake that costs people a return is measuring in the wrong place. The Kelly belt is worn where a dress or a coat sits, which is usually higher than jeans and usually a few centimetres smaller. Measure there — at the natural waist if it is going over a dress, or over the coat if it is going over a coat — with a tape held snug but not tight, and read the number in centimetres. Then choose the size closest to it. If the measurement is 77, take the 75, which puts you on the fourth hole rather than the middle; if it is 78, the 80.
If you already own a belt that you wear at that height, measure it from the buckle pin to the hole you use and tell us that number instead. It is the most reliable method there is, because it measures the belt you actually wear rather than the body you think you have. Either way, we confirm the size before ordering anything.
The colours
Black in Epsom is the first to sell out every season and is permanent. Gold — the house tan — is permanent and the second most requested. Etoupe, the grey-taupe, is the quiet one that goes with the most. White and Craie appear for summer and should be asked for early. The reds, the blues — Bleu Nuit, Bleu Brume and the season's shades — and the greens rotate, and a colour that has finished is not remade. The hardware is gold-plated or palladium-plated; gold is the more popular with black and Gold, palladium with Etoupe and the blues.
The Kelly belt comes in fewer colours than the H belt because there is no reverse side to play with. If you want a specific seasonal colour in a specific size, ask while it is in the boutiques; we look across them, and we say plainly when one has finished everywhere.
Living with one
Epsom is the right leather for a belt: it is embossed, holds its shape, does not scratch easily and does not stretch. The hardware is plated, so keep it away from perfume and do not let it sit against a steel watch in a drawer. The straps that go over the touret are the wearing part; after a couple of years of daily use they soften and the holes elongate slightly, which is normal and does not affect the closure. Kept in its box between wears, a Kelly belt looks new for a very long time.
Buying it in the UK
The London boutiques hold black and Gold in the middle sizes most of the time, and everything else intermittently. The UK website shows the central stock. Both are at £1,080, and neither can sell you a size it does not have — and the 70 and 75 in black are the ones that go.
Through us, the Kelly belt is £865 and the Kelly Pocket £1,345 — new, unworn, with a copy of the boutique receipt and the orange box, in seven to ten days. We source across boutiques, so a size and colour that is finished in London is usually sitting in another, and we confirm the size against your measurement before it is bought. The colours and the request button are on our Kelly belt sourcing page; the H belt has its own page. Pieces we hold in the showroom, including pre-owned belts when they come through, are in the belts gallery.
Copies of both belts are everywhere, and the H buckle in particular is one of the most-copied objects the house makes. Buy new with a receipt, or from a seller who states the condition and provenance in writing. Our guide to authenticating Hermès covers what that documentation should look like.
Frequently asked questions
How much is the Hermès Kelly belt in the UK? £1,080 at the UK boutiques and on the UK website for the Kelly 18 belt in Epsom, as of September 2026; the Kelly Pocket 18 is £1,680. Through JULL the Kelly belt is £865, new and unworn with a copy of the boutique receipt.
What size Kelly belt should I buy? Measure where you will wear it — the natural waist for a dress, over the coat for a coat — in centimetres, and choose the closest size from 65 to 105. Or measure a belt you already wear at that height from the pin to the hole you use. We confirm the size before ordering.
Is the Kelly belt reversible? No. The Kelly belt is one leather in one colour with the Kelly closure sewn on. The reversible belt with the removable buckle is the H belt, which is a different product at £825.
Kelly belt or H belt? H belt for trousers and jeans and for the option of two colours; Kelly belt for dresses, knits and coats, where the turn-lock shows. If you can only have one and you wear belts through loops most days, the H belt.
Are the Kelly belts you source new? Yes — new and unworn from an Hermès boutique, with a copy of the receipt and the orange box. JULL is an independent dealer and is not affiliated with Hermès.
Can you find a size or colour that has sold out in London? Usually. We source across boutiques, so the 70 or 75 in black that London has finished is often available elsewhere. If a colour has finished everywhere we tell you within a day.
