Saint Laurent : les artisans qui font le travail

The atelier sits on the third floor of 5 Avenue Marceau, where the windows face west and the light goes soft around four. That's when Dominique Veillon likes to check a sleeve head, because the raking angle shows whether the cap sits clean or fights the bicep. She's been Premier d'Atelier Tailleur at Saint Laurent since 2004, which means she runs the tailoring workroom and has final say on every jacket that leaves it.

You won't find her name on the label. You will find her hands in the way a 1967 Le Smoking jacket still fits a contemporary shoulder, because Veillon and her team maintain the archive patterns and translate them into each new collection. When Anthony Vaccarello references Yves Saint Laurent's 1971 Libération collection or pulls a 1980s tuxedo shape forward, it's Veillon who ensures the proportions survive the journey.

This is not romantic. It is specific, technical work conducted in a language most customers will never speak.

The people who make the jacket

Saint Laurent's Paris ateliers employ around 180 petites mains — the term is both diminutive and absolute. These are the sewers, cutters, and finishers who transform Vaccarello's sketches into cloth. The structure is rigid: apprentices, secondes mains, premières mains, and above them the premiers d'atelier who run each workroom. Flou handles dresses and soft construction. Tailleur does tailoring. Each operates as a semi-autonomous unit with its own quality standards and workflow.

Veillon came up through the old system. She trained at the École de la Chambre Syndicale in the late 1980s, then worked at Chanel and Dior before joining Saint Laurent under Tom Ford's tenure. Her technical director is Sylvie Thibault, who manages the cutting tables and ensures each pattern piece is oriented correctly on the bolt. Thibault has been with the house since 1998. She remembers when the Rive Gauche ready-to-wear line still operated separately from haute couture, before Gucci Group consolidated everything under one roof.

The jacket you see on the runway starts with her. Thibault receives the toile — the muslin prototype — from the modéliste, checks it against Vaccarello's notes, and marks where the pattern needs adjustment. Then it goes to the cutters, who lay the fashion fabric and cut each piece with a tolerance of two millimetres. If the fabric is a stripe or a check, the cutter must match the pattern across every seam. This is not automated. A Saint Laurent blazer has between forty and sixty individual pieces depending on the style. Each one is cut by hand.

What the house keeps

Saint Laurent's archive holds over 5,000 patterns dating back to the maison's 1961 founding. These are stored as paper templates in a climate-controlled room on the second floor. When Vaccarello wants to reference a specific jacket — say, the 1966 Pop Art collection's velvet smoking or the 1971 Scandal collection's sheer blouses — the modélistes pull the original pattern and grade it to contemporary sizing.

This is where Marie-Amélie Berthomieu's work becomes visible. She's been head modéliste at Saint Laurent since 2011, responsible for translating Vaccarello's vision into patterns that can be reproduced at scale. Berthomieu trained at Studio Berçot and spent a decade at Balenciaga before joining Saint Laurent under Hedi Slimane. Her job is to maintain continuity between eras while allowing each creative director to impose their own proportions.

Under Vaccarello, that means a longer, narrower shoulder and a higher button stance than Slimane preferred. The Le Smoking jacket's lapel width has shifted three times in the past decade. The 2024 version sits at 8.5 centimetres, slightly wider than Slimane's 7.8 but narrower than Ford's 9.2. Berthomieu adjusts these increments while preserving what she calls "the Saint Laurent shoulder" — a clean, structured line that doesn't collapse or pull.

She works with a team of six modélistes, each responsible for different categories. Sandrine Gallet handles knitwear. Isabelle Maury does evening wear and embroidered pieces. When Vaccarello shows a beaded mini dress that weighs four kilos, Maury is the one who calculated how to distribute that weight so the model can walk without the hem sagging.

The fittings no one photographs

Every Saint Laurent collection goes through at least four fittings before production. Vaccarello attends the first and last. In between, the atelier works through a list of corrections that can run to thirty points per garment. Sleeve pitch. Hem balance. Whether the collar sits flat when the model turns her head.

Veillon keeps a notebook where she records every adjustment. If a jacket's shoulder needs to come forward by half a centimetre, she notes it. If the lining pulls when the model raises her arm, she notes that too. These observations accumulate into a technical language that allows the atelier to reproduce the garment for production. A runway sample might take sixty hours to construct. The production version needs to be achievable in twelve.

This is where Anne-Sophie Pichon's role becomes critical. She's the technical director for Saint Laurent's ready-to-wear production, which means she translates atelier samples into specifications that can be executed by external workshops. Saint Laurent manufactures its tailoring in Italy, mostly around Florence and Naples. Pichon visits these workshops every six weeks to check quality and troubleshoot problems. If a factory can't achieve the correct shoulder shape, she brings the sample back to Paris and Veillon's team re-cuts the pattern.

The system depends on this feedback loop. The atelier makes the ideal version. Pichon figures out how to produce it at scale without losing the details that make it recognisable as Saint Laurent.

What doesn't change

Certain techniques remain non-negotiable. Saint Laurent's tailored jackets still use a horsehair canvas in the chest, hand-basted to the outer fabric. The sleeve head is padded with a thin layer of wadding, shaped by hand to create a smooth cap. The buttonholes are sewn by machine but finished by hand — a premières main named Chantal Rousseau has done most of them for the past eighteen years.

These methods are slower and more expensive than fused construction or fully automated finishing. They also produce a jacket that moves differently, because the canvas and padding create a buffer between body and cloth. When you wear a Saint Laurent blazer, it doesn't cling. It suggests.

Vaccarello has maintained these standards since he took over as creative director in 2016. His aesthetic is sharper and more overtly sexual than his predecessors', but the construction remains rooted in the techniques Yves Saint Laurent established in the 1960s. The house has changed hands multiple times — bought by Gucci Group in 1999, absorbed into Kering in 2005, rebranded from Yves Saint Laurent to Saint Laurent in 2012 — but the atelier's methods have remained relatively stable.

Veillon attributes this to institutional memory. The premières mains train the secondes mains, who eventually become premières themselves. Knowledge transfers through repetition and correction, not through written manuals. When a new technique is introduced — Vaccarello occasionally requests a construction method he's seen elsewhere — the atelier tests it against their existing standards. If it compromises the jacket's structure or longevity, they refuse it.

This is not obstinacy. It's quality control enforced by people who will still be working at 5 Avenue Marceau long after the current collection is discounted.

What comes next

The fashion system doesn't reward this kind of continuity. Collections turn over every six months. Trends accelerate and collapse within a season. Saint Laurent's atelier operates on a different timescale, where a jacket's value is measured in how long it remains wearable rather than how quickly it sells.

Veillon will retire in the next five years. Thibault is already training her replacement, a première main named Laetitia Moreau who has been in the atelier since 2008. Berthomieu is forty-six and shows no signs of leaving. The system is designed to outlast individuals.

Whether it can outlast the economic pressures reshaping luxury production is less certain. Kering reported a 14 per cent revenue decline for Saint Laurent in the third quarter of 2024, driven by softening demand in China and the US. The company has not announced cuts to the atelier, but the ready-to-wear production budget is under review.

For now, the work continues. Veillon checks a sleeve head in the late afternoon light. Thibault marks a pattern adjustment. Rousseau finishes a buttonhole by hand. These are the people who make Saint Laurent what it is, whether or not the customer knows their names.
