The atelier sits above a narrow street in the 10th arrondissement, four floors up, no plaque

The atelier sits above a narrow street in the 10th arrondissement, four floors up, no plaque. Inside, three pattern-cutters are draping muslin over a dress form. The designer is not present. He is, one assumes, in Marseille or Miami or wherever the next campaign demands. The cutters remain.

This is not unusual. What is unusual is how rarely their names appear in print.

Jacquemus has built a house on a particular kind of image: sun, straw hats, a certain idea of the South. The Le Chiquito bag — palm-sized, architectural, borderline unusable — became shorthand for the brand in 2018. It appeared on every arm that mattered. It was credited, in the usual way, to Simon Porte Jacquemus himself. The technical drawing, however, came from the hands of Léa Peckre, a leather-goods designer who had worked at Moynat before joining the Jacquemus team in 2017. She left in 2020. Her name does not appear on the house website.

This is not an indictment. It is how the industry functions. A designer's name is the house. The house is a collective. The collective remains, by design, anonymous.

The structure beneath the image

Jacquemus employs roughly sixty people in its Paris studio. A portion work in design and development. The rest handle production liaison, fabric sourcing, and sample coordination. The atelier itself — the space where toiles are cut and first samples assembled — operates with a core team of eight. They are pattern-makers, not couturiers. The distinction matters. A couturier builds a garment from start to finish. A pattern-maker translates a sketch into geometry, then into fabric, then into instruction sets for the factories in Portugal and Tunisia where Jacquemus produces the majority of its ready-to-wear.

The head of the atelier is Claire Vasseur. She joined in 2015, the year before the brand's first proper runway show. Before that, she worked at Courrèges under Sébastien Meyer and Arnaud Vaillant, and before that at Acne Studios in Stockholm. Her job is to make the impossible wearable. A sketch of a dress with no visible seams must become a dress with seams, because fabric does not yet grow on trees. She decides where those seams go. She decides how the bias will behave under tension. She decides, in many cases, whether the garment can exist at all.

In a 2022 interview with System magazine, Jacquemus described his process as instinctive. "I don't sketch much," he said. "I drape, I cut, I pin." What he did not say is that he drapes and cuts and pins with Vasseur and her team, and that the pins are later translated into patterns by people who understand grain and ease and the difference between a sketch and a specification.

The bag, reconsidered

Return to the Chiquito. It measures nine centimetres across. It holds a lipstick, a credit card, perhaps a house key if the key is slim. It retailed, at launch, for 390 euros. Today it sells for around 550.

The bag's structure is deceptively simple: a rectangular base, four trapezoidal sides, a single top-handle. It closes with a magnetic snap. The leather is vegetable-tanned calfskin, sourced from a tannery in the Marche region of Italy. The stitching is done by machine, not by hand, at a factory outside Porto. The hardware — handle mounts, logo plaque, interior snap — is cast in Guangzhou and finished in Italy.

Peckre's original concept drawing specified a bag roughly twice the final size. Jacquemus, according to a member of the development team who requested anonymity, pushed for smaller. The proportions became absurd, then arresting. The bag became a sculpture one could buy.

But Peckre did not work alone. The technical pattern was refined by Mathieu Leclerc, a leather-goods technician who had previously worked at Delvaux. The choice of closure — magnetic rather than turn-lock — was driven by cost and scale. A turn-lock would have required a thicker leather to support the hardware. Thicker leather would have made the bag heavier, less playful, less Jacquemus. Leclerc proposed the magnet. Jacquemus approved it. The bag went into production.

Leclerc left the house in 2021. He now works for Coperni.

The fittings no one photographs

A fitting at Jacquemus involves four people, sometimes five. The designer. The head of atelier. A fit model. A sample coordinator who records every adjustment in a shared document that will later be sent to the factory. Sometimes a fabric technician is present, if the material behaves in unexpected ways.

The fittings happen in a white-walled room with north-facing windows and a full-length mirror. They last between twenty minutes and two hours. Jacquemus speaks quickly, in French, occasionally in English when a term is more precise. He gestures. He pulls fabric. He asks the model to sit, to walk, to raise her arms. Vasseur makes notes on the toile with a fabric pen. The sample coordinator photographs each angle.

Afterward, Vasseur returns to the atelier. She adjusts the pattern. A new toile is cut. The process repeats until the garment behaves as intended. For a simple dress, this might take two iterations. For a structured jacket, it can take eight.

None of this appears in the campaign imagery. The campaign shows a woman in a field, or on a beach, or against a wall of bougainvillea. The dress moves beautifully. That it moves beautifully is not an accident.

What is owed, what is given

There is a tension here, and it is not unique to Jacquemus. A fashion house is a hierarchy. The designer's name is the brand. The brand is the business. The business requires a single authorial voice, a clear point of view, a face one can interview and photograph. To distribute credit is to dilute the message.

And yet the work is collective. The dress exists because someone drafted the pattern. The bag exists because someone specified the thickness of the leather and the placement of the stitching. The runway show exists because someone coordinated the samples and someone else managed the fittings and someone else liaised with the factory to ensure the garments arrived on time.

In other industries, this labour is acknowledged. A film has credits. A building has an architecture firm, and within that firm, a list of associates. Fashion resists this. The reasons are partly practical — a runway show involves dozens of contributors, and listing them all would be cumbersome — and partly mythological. The myth of the singular genius is good for business.

Jacquemus, to his credit, has occasionally named his collaborators in interviews. In a 2021 conversation with AnOther magazine, he mentioned Vasseur by name and described her as "the person who makes everything possible." He has posted photographs of the atelier team on Instagram. These gestures are not nothing.

But they are also not credits.

The next chapter, whoever writes it

The house is expanding. A menswear line launched in 2019. A beauty line is rumoured for 2025. The atelier has grown from eight to twelve. Vasseur now manages two assistant pattern-makers and a dedicated team for leather goods.

Simon Porte Jacquemus remains the face, the name, the vision. But the work, as always, is plural. The hands that cut the patterns, that specify the stitching, that test the closures and adjust the hems — those hands belong to people whose names one must search for, if one searches at all.

Whether this will change is unclear. The industry has not, historically, rewarded transparency. It has rewarded spectacle, and spectacle requires a single star.

Still, one notes the shift in other quarters. Phoebe Philo credited her atelier by name when she launched her own line. The Row lists its production partners on its website. These are small gestures, but they suggest a different model might be possible.

For now, the atelier in the 10th arrondissement continues its work. The cutters drape muslin. The patterns are refined. The samples are sent to Porto. The bags arrive in boutiques, each one a small miracle of geometry and craft, each one bearing a single name.
