Épernay Corsetry and Lingerie Construction

Corseterie

Épernay, in the Marne department, is home to the last operating corsetry workshop in France — the Chantelle factory, where roughly 85 seamstresses hand- and machine-construct structured lingerie using techniques with no remaining external training source in the country. A single bra is a puzzle of more than 25 components — lace, tulle, elastic fabric, underwires, hooks, and straps — assembled across some forty distinct operations, each requiring its own dedicated equipment; every individual lace motif is hand-positioned before assembly specifically to guarantee left-right symmetry, and new recruits take about three months to learn the foundational hand-gestures, taught entirely in-house since no outside corsetry school exists. The company traces its origin to 1876 in Romilly-sur-Seine, Aube, where François Gamichon and the Kretz family developed an elastic knit fabric to make corsets less restrictive — an innovation lineage that runs through to SoftStretch, a patented technical stretch fabric the workshop produces today. New designs pass a distinctive human-centered quality process: employees take prototypes home in mesh pouches, wear them for weeks, and report fit failures — short straps, a riding back band, compressive underwires — back to the design office. The workshop was recognized in 2025 with France's Entreprise du Patrimoine Vivant (Living Heritage Company) label and now also manufactures for roughly sixty other French lingerie brands seeking local production.

Risk level: Critically Endangered · Not inscribed; the workshop holds France's official Entreprise du Patrimoine Vivant (Living Heritage Company) label, awarded 2025 — a state designation created in 2005 under the Ministry of Economy and Finance for enterprises with rare or exceptional artisanal/industrial expertise

Alternate Names
French lingerie manufacturing; Chantelle savoir-faire; bra-making (construction de soutien-gorge)
Geographic Center
Épernay, Marne department, Grand Est (the sole surviving operational site, opened 1962); historical origin at Romilly-sur-Seine, Aube department, Grand Est
Community / Ethnic Group
Chantelle's workforce — approximately 85 seamstresses (couturières) as of 2026, plus supporting technical and design staff
Estimated Origin
1876, Romilly-sur-Seine — François Gamichon, with the Kretz family (sources vary on whether their formal involvement began at the 1876 founding or as late as 1898), developed an elastic knit fabric to make corsets less restrictive. The Chantelle brand name was adopted in 1948 or 1949 (sources vary). The Épernay site itself opened in 1962.
Cultural Function
Manufacture of structured foundation garments — historically corsets and girdles, now primarily bras — for the French and international lingerie market; the last surviving vestige of what was once a substantial French corsetry and hosiery manufacturing sector
Primary Materials
Lace, tulle, elastic fabrics (including a patented technical stretch fabric, SoftStretch), underwire/boning (armatures), hooks and closures, straps — more than 25 distinct components in a single finished bra
Primary Tools
Cutting tables; specialized sewing machines — each of the roughly 40 manufacturing operations per garment requires its own specific equipment; measuring and positioning tools for hand-placement of lace motifs
Process Overview
Lace and fabric sourcing → cutting → hand-positioning of lace motifs for symmetry → component assembly (banding, cups, transversal seaming, strap and closure attachment) across roughly forty operations → quality inspection → prototype wash and wear-testing for new designs → finishing
Traditional Applications
Corsets (historical), then girdles (gaines), evolving to modern structured bras (soutiens-gorge)
Contemporary Applications
Premium Chantelle lingerie lines; contract manufacturing for roughly sixty additional French lingerie brands seeking local, small-batch, or heritage production
Notable Practitioners
Delphine Chapelot — site director (directrice du site), Épernay workshop, responsible for training transmission since no external corsetry school exists. Guillaume Kretz — CEO of Groupe Chantelle since July 2023 (previously the group's deputy general manager/directeur général), sixth generation of the founding Kretz family. Renaud Cambuzat — Global Chief Creative & Brand Officer of Chantelle. Individual seamstresses documented by first name only in the source profile: Anaïs (elastic banding), Laurence (cup assembly), Isabelle (transversal seaming); one unnamed seamstress with 42 years at the workshop, nearing retirement. Approximately 85 seamstresses work at the site in total.
