Where can you buy an Hermes Constance in London today? There are two honest answers. The Hermes boutiques on New Bond Street and at Harrods and Selfridges sell the Constance at retail, but it is one of the most rarely offered bags in the house's range: it is not displayed openly, and most clients are quietly invited to consider one only after an established purchase history. The faster route is a specialist secondary-market dealer. JULL, a London specialist in authenticated new, unworn and pre-owned Hermes, typically holds several Constance bags in stock that can be viewed in person and purchased the same day.
This guide covers the sizes, what a Constance actually costs in London in 2026, how the boutique route compares with a specialist, and what to check before any money moves.
Why the Constance is so hard to find
The Constance was designed in 1959 by Catherine Chaillet and named after her daughter. It is the house's definitive shoulder bag: a clean rectangular body, a long strap that wears on the shoulder or crossbody, and the great lacquered or metal H clasp that makes it recognisable across a room. Because production is small and demand from collectors is constant, the Constance sits alongside the Birkin and Kelly in the group of bags that Hermes boutiques allocate rather than simply sell. Walking into a London boutique and buying one off the shelf is, in practice, not how it happens.
That is why most Constance bags in London change hands on the secondary market — and why the model holds its value so firmly there.
Constance sizes: 18 or 24
Two sizes account for almost every Constance sold today. The Constance 18 — often called the mini — is 18 cm wide and has become the modern favourite: it takes a large phone, cardholder and keys, and reads as an evening and daytime bag at once. The Constance 24 is the classic proportion, noticeably roomier, and suits anyone who found the 18 a size too disciplined. Rarer variants exist — the micro 14, and the Constance To Go with its interior wallet fittings — and appear in our mini bags gallery when we have them.
If you are choosing between the two: the 18 is the one most requested in our London workroom, and the one that tends to leave stock fastest.
What a Constance costs in London in 2026
Hermes does not publish waiting lists or guarantee allocation, so the meaningful price is the secondary-market one. In London we currently see authenticated Constance 18 and 24 in the standard leathers — Epsom, Swift, Box — typically offered in the range of roughly eight to fifteen thousand pounds depending on leather, colour, hardware and condition, with Box calf, rare colours and exotic skins above that. Prices move with the market; treat any figure as an observation of what we see today rather than a promise. Every piece on our Constance page shows its exact price, and where a piece was sourced below boutique retail we say so plainly.
Boutique or specialist: which route suits you
The boutique route offers retail price and the full Hermes ritual, at the cost of time and uncertainty: no list to join, no guarantee an offer ever comes, and no choice of colour when it does. The specialist route costs more for sought-after combinations but removes every unknown: you see the exact bag, in the exact colour, today.
A serious specialist should make that trade feel safe. Our standard at JULL: every Constance is authenticated by hand in our London workroom before it is listed — clasp engraving, blind stamp, stitching, hardware and leather grain checked against production records; each bag is photographed honestly, sold with an itemised invoice recording the blind stamp, and delivered with a tamper-evident security seal. You can book a private viewing before deciding anything, and our published Refund Policy sets out exactly where you stand. For the questions worth asking any seller — not just us — see our guide to choosing a Hermes reseller in London.
How to check a Constance is genuine
The Constance has its own tells. The H clasp should sit perfectly centred with crisp casting and no rattle; the strap anchors should be tight; the blind stamp — the small embossed code dating the bag — should match the era of the hardware and lining construction; and the interior pockets should follow the correct layout for the size and year. Our full walkthrough is in How to Authenticate an Hermes Bag, and the terms are decoded in the Hermes Glossary. If you are buying elsewhere and want a second opinion before you commit, we are happy to give one.

Frequently asked questions
Can I buy a Constance directly from an Hermes boutique in London? At retail, yes — but the Constance is allocated, not openly sold. Offers generally follow an established purchase history with the boutique, and neither timing nor colour can be chosen.
Which Constance size holds demand best? In our experience the Constance 18 is the most requested size in London today, particularly in neutral colours with gold hardware. The 24 has a steadier, classic following.
How much is an Hermes Constance in London in 2026? On the authenticated secondary market we typically see standard-leather 18s and 24s from roughly eight to fifteen thousand pounds, with rare colours, Box calf and exotics above that. Exact, current prices are on each listing.
Is a secondary-market Constance safe to buy? From a specialist who authenticates in-house, documents the blind stamp on the invoice and publishes a refund policy — yes. The risks concentrate in private sales with no paperwork.
Can I see a Constance before paying? At JULL, always. Book a viewing and compare sizes side by side in person.
