Chore Coat or Bleu de Travail?

The English and Americans call it the chore coat. The French call it the bleu de travail. The version we’re talking about here first appeared in the late 1800s with proudly working-class roots: the humble work jacket.

People have always worn specific clothes for work—mainly to protect themselves and to save their “good” clothes from wear and tear. Back in the Middle Ages, workwear was also a clear social marker: what you wore, whether a shirt or a hat, told others what trade you belonged to.

Waist-length, unlined, with wide armholes for ease of movement—the classic work jacket is one of the most durable garments ever made. The shade of blue often varied depending on the profession, and the fabric was usually thick cotton moleskin: soft to the touch but incredibly tough. It featured reinforced stitching, sturdy buttons (usually metal or resin), and the signature pocket layout: two large ones for tools and a smaller chest pocket (sometimes with a hidden fourth pocket inside).

The bleu de travail quickly became a symbol of an entire social class—manual laborers—standing in contrast and opposition to the bourgeoisie. It became a battle of blue collars versus white collars, and when this clash moved into the streets, the work jacket transformed from a functional uniform into a political statement.

In the 1960s and ’70s, students and leftist intellectuals adopted it in solidarity with the working class. It went from workwear to ideological manifesto.

When the dust settled, the bleu de travail found a new home in the wardrobes of free spirits, bohemians, and anyone who still wanted their clothing to say something.

By the late ’70s, though, it started to fade from view. The ’80s were all about flashiness, tech, and upward mobility—not exactly the right moment for a garment so deeply tied to working-class identity.

But then came deindustrialization in Europe.

That’s when the work jacket began to reappear—in second-hand markets and in the warehouses of abandoned factories. Fashion lovers rediscovered them, and big brands soon caught on: this jacket had everything—authenticity, versatility, and premium materials.

Some say the French work jacket was inspired by the indigo cotton uniforms worn by Chinese sailors. Maybe it’s a sartorial legend, but it speaks to the power of invisible exchanges stitched into the seams of history.

Between the two World Wars, in port cities like Algiers and Marseille, local dock workers came into contact with sailors from East Asia. These sailors wore lightweight indigo cotton suits—loose trousers and straight-cut buttoned jackets, similar to traditional Tang jackets.

Sturdy, breathable, and well-suited to warm climates, these garments caught the attention of port workers, who began adopting similar pieces for everyday wear.

After WWII, workwear manufacturing ramped up in those very places—Algiers (still under French colonial rule at the time) and Marseille, which became a key hub for professional clothing production.

Coincidence, or silent cultural exchange across ships and harbors? Either way, the connection is a compelling one. After all, popular fashion is often born where the world overlaps—and ports have always been the place where everything begins.
