The Hands Behind the Le Smoking

The atelier on Avenue Marceau runs quiet most mornings. By nine, the cutters are already at their tables, pattern pieces pinned to navy gabardine, chalk lines tracing the rake of a lapel that hasn't changed meaningfully since 1966. The jacket in question — Saint Laurent's Le Smoking — requires forty-two hours of work from first cut to final press. Fewer people can name the artisans who make it than can recite Yves Saint Laurent's biography.

Start with Madame Colette Rousseau, première d'atelier tailleur for twenty-three years. She joined the house in 2001, trained under the last generation who worked directly with Monsieur Saint Laurent. Her responsibility is the shoulder. Not the pad, which is cut separately and basted in by a second hand, but the way the sleeve cap meets the body — what tailors call the tête de manche. Get it wrong and the jacket pulls across the back or collapses forward. Get it right and the thing sits like it grew there.

Rousseau came up through the Chambre Syndicale, the old system. Three years of technical training, another two as a junior hand in an atelier that no longer exists. She worked at Dior briefly, then Chanel, before Saint Laurent. The jump wasn't lateral. Each house has its own grammar. At Chanel, the shoulder is soft, almost Neapolitan. At Saint Laurent, it carries more structure — not the roped spalla camicia of Milan, but a clean, defined line that holds its shape through a dinner service.

"People think we use a standard pad," she told System magazine in 2019. "We don't. Every shoulder is built by hand, shaped to the client's posture." For ready-to-wear, that means a template adjusted across three fittings with a house model. For haute couture, it means Rousseau stands in the room while the client moves, watches how they hold a glass, whether one shoulder sits higher than the other.

The cloth itself comes from a mill outside Huddersfield — 10oz barathea for evening, 11oz grain de poudre for day wear. It's the same supplier Monsieur Saint Laurent used in the Seventies, though the weights have crept up slightly. Modern centrally heated rooms don't demand the same insulation. The bolt arrives pre-shrunk, but Rousseau still steams each length before cutting. Wool has memory. If you don't relax it first, the seams will pucker after the first dry clean.

Her cutting table is Canadian maple, forty years old, surface worn smooth in the centre where her hands move. She works without a rotary cutter, uses eight-inch shears that were her grandmother's. The pattern pieces are traced in tailor's chalk, never pen. Chalk brushes off. Pen doesn't. She cuts on the straight grain for the body, bias for the collar, always leaving a half-inch seam allowance. The house standard is five-eighths, but Rousseau prefers the narrower margin. Easier to control the roll of the lapel.

After cutting comes assembly, and that falls to Étienne Marchand. He's been with Saint Laurent since 2007, works exclusively on tailoring. His station is near the north-facing window — best light, no direct sun to fade the thread. He hand-bastes the jacket before it goes to the machine, uses silk thread that will be pulled out later. Basting isn't strictly necessary for ready-to-wear, but it's how he was taught, and it's how the jacket holds its shape through the first fitting.

Marchand trained in Lyon, which has a different tailoring tradition than Paris. More emphasis on the waist suppression, less on the shoulder. He had to unlearn some of that when he arrived. Saint Laurent's Le Smoking sits straight through the body, minimal darts, the silhouette defined by the cut rather than internal shaping. It's closer to a man's dinner jacket than a woman's blazer, which was the point in 1966 and remains the point now.

The buttonholes are his domain. Four on each cuff, one at the waist, none of them functional on the ready-to-wear version. They're worked by machine now — a 1950s Reece that the house bought second-hand and refuses to replace — but Marchand still finishes each one by hand, trimming the loose threads with a surgical blade, checking that the bar tacks sit parallel. On the haute couture version, all five buttonholes are hand-worked. It takes him forty minutes per hole. The thread is silk, the same black as the cloth, which means any mistake shows immediately.

He doesn't find the work repetitive. "Each jacket is different," he said in a 2021 profile in Le Figaro. "The cloth behaves differently depending on humidity, the client's measurements shift between fittings. You're solving small problems all day."

The collar and lapels go to Anaïs Moreau, who joined the atelier in 2015. She's the youngest of the three, came up through a vocational programme that didn't exist when Rousseau started. Her job is to ensure the collar sits flat against the neck and the lapels roll without gapping. It sounds simple. It isn't.

The under-collar is cut from a coarser cloth — usually a wool-and-hair blend — and pad-stitched to give it structure. Moreau works the stitches in a chevron pattern, each row a quarter-inch apart, tension even across the entire piece. If the stitches are too tight, the collar curls. Too loose, and it won't hold its shape. She uses a thimble on her middle finger, pushes the needle through with the side of her hand rather than the tip of her finger. Faster that way, and easier on the joints.

Once the under-collar is ready, she bastes it to the top collar, easing in a slight curve so the two layers sit naturally when worn. The lapels are faced with grosgrain, hand-stitched along the edge to prevent the facing from rolling out. The stitches are invisible from the front, barely visible from the inside. Moreau uses a single strand of silk thread, waxed to prevent tangling, and works under a daylight lamp even when the sun is out.

The final press happens in a room at the back of the atelier, where two industrial steamers run all day. The jacket is pressed in sections — sleeves first, then body, then collar — using a wooden buck shaped like a torso. The presser, whose name the house declined to share, works without a timer, judges doneness by eye and touch. Too much steam and the wool goes shiny. Too little and the seams don't set.

What comes next is less certain. Rousseau is sixty-two, eligible for retirement in three years. Marchand has been approached by other houses, though he hasn't said whether he'll stay. Moreau is being trained on cutting, which suggests the house sees her as a successor, but atelier roles aren't always linear.

Saint Laurent has opened a training workshop in partnership with the Chambre Syndicale, aimed at bringing younger hands into the trade. The first cohort graduated last year. Whether they'll stay — whether the work will hold them the way it held Rousseau — is an open question. The jacket takes forty-two hours. The skill takes longer.
