The Le Smoking sits in the Musée Yves Saint Laurent Paris behind glass

The Le Smoking sits in the Musée Yves Saint Laurent Paris behind glass. Black grain de poudre wool. Satin lapels. The shoulders are narrow by today's standards. The trousers have no stretch. In 1966, a woman could not wear this into most Paris restaurants. By 1975, she could wear it anywhere.

That is the distance Saint Laurent travelled in nine years.

Rive Gauche, 1961–2002

Yves Saint Laurent opened his house at 30 bis rue Spontini in 1961. He was twenty-five. He had spent three years at Dior, where he succeeded Christian Dior himself at twenty-one, then been conscripted, then hospitalised, then released. His business partner Pierre Bergé secured backing. The first collection showed in January 1962.

The early work was refined, controlled, younger than Dior but still within the vocabulary of haute couture. Then Saint Laurent began to look outside. He looked at the street. He looked at men's tailoring. He looked at Mondrian, at Africa, at the uniforms of service workers and soldiers. In 1966, he put a woman in a tuxedo and called it Le Smoking. The same year, he opened the first Rive Gauche boutique on the rue de Tournon, selling ready-to-wear under his name—a move that fractured the traditional hierarchy of couture.

This was not borrowing. It was appropriation in the most literal sense: taking a garment that belonged to one context and relocating it entirely. The safari jacket. The pea coat. The trench. The jumpsuit. Saint Laurent made each one a template. He understood that power dressing was not about softness or accommodation. It was about taking the uniform and refusing to modify it.

The 1970s were the house's most prolific years. The collections moved faster than fashion could absorb them. Peasant blouses, Ballets Russes, Chinese opera, forties shoulders, transparent blouses worn with nothing underneath. He worked in primary colours and in black. He cut like a man's tailor and draped like Madame Grès. The through-line was precision.

By the late 1980s, the pace had slowed. The collections repeated motifs. Saint Laurent himself appeared less frequently. The final haute couture show was in January 2002. He wore a navy peacoat and stood on the runway for thirteen minutes while the audience stood and applauded. He was sixty-five. He had been working for forty-four years.

Pilati, Slimane, Vaccarello

Tom Ford's tenure—1999 to 2004, overlapping with Saint Laurent's final years—reset the commercial logic of the house. He made it desirable again, which also meant making it louder. The silhouette was overt. The advertising was explicit. It worked. When Gucci Group sold to PPR in 2004, Ford left.

Stefano Pilati followed. His seven years are under-discussed. He was quieter than Ford, more interested in fabric than in spectacle. The silhouette softened. The palette moved into grey, rust, deep green. Pilati worked in increments. He did not try to rewrite the house. He tried to let it breathe. The clothes were wearable in a way Ford's had not been, but wearable did not move product at the necessary velocity.

Hedi Slimane arrived in 2012 and removed the 'Yves.' The house became Saint Laurent Paris. He moved the atelier from Paris to Los Angeles, then back to Paris. He showed in Los Angeles twice. The silhouette was his silhouette: narrow, androgynous, built for tall thin boys and the women who wore the same size. The photography was black-and-white, high-contrast, shot in Malibu and London and wherever Slimane was living. It looked nothing like Yves Saint Laurent's work and it looked completely like it—the same attraction to youth, to the night, to the idea that fashion is a place you escape into.

Slimane's commercial impact was undeniable. Revenue more than doubled. The waiting list for certain boots ran six months. But the vocabulary was narrow. After four years, it began to repeat itself.

Anthony Vaccarello took over in 2016. He had worked at Fendi and run his own line. His first collections were cautious, still in Slimane's shadow. Then he found a register: long, lean, explicitly sexual, but with a kind of remove. The hemlines dropped. The necklines opened. The tailoring stayed sharp. He brought back some of the archival codes—Le Smoking, the saharienne, the blouse—but he did not recreate them. He used them as reference points, not as product.

The current Saint Laurent is not trying to be Yves Saint Laurent. It is trying to be a house that knows what Yves Saint Laurent did and has decided which parts of that to carry forward. Vaccarello's shows are consistent. The silhouette is recognisable. The house is profitable. That is a different kind of achievement than invention, but it is an achievement.

What Remains

Saint Laurent no longer makes haute couture. The atelier still exists, but it serves ready-to-wear and special orders. The house is part of Kering, which also owns Gucci, Bottega Veneta, Balenciaga, and Alexander McQueen. It is a luxury conglomerate. The decisions are made in boardrooms as much as in ateliers.

But the Le Smoking still fits. The proportions have shifted—wider shoulders now, a longer jacket, trousers that break at the ankle—but the idea is intact. A woman can still walk into a room in a black tuxedo and the room will notice. That is what Saint Laurent built. Not a single garment, but a premise: that a woman in menswear is not dressed as a man. She is dressed as herself, in clothes that were not made for her, which she has claimed.

The safari jacket is still in the collection every few seasons. So is the trench, the peacoat, the pussy-bow blouse. They are not recreations. They are variations. The house is working off its own archive, which is both a limitation and a foundation.

What Yves Saint Laurent understood—and what the house still understands—is that fashion is not about the future. It is about the present, which contains the past. The Le Smoking was not futuristic in 1966. It was a tuxedo. It had existed for seventy years. Saint Laurent just put it on a different body.

On the rue de Tournon, the original Rive Gauche boutique is now a different store. The Musée Yves Saint Laurent Paris is at 5 avenue Marceau, in the former haute couture atelier. The permanent collection includes the Mondrian dress, several Le Smokings, a beaded matador jacket, and the navy peacoat from the final show. The coat is displayed on a mannequin facing the window. The label inside reads "Yves Saint Laurent Haute Couture, Hiver 2002." The stitching is done by hand.
