Denim

The most global of fabrics hides two European cities in its name. “Denim” comes from the French phrase serge de Nîmes — “serge from Nîmes” — serge being a type of sturdy twilled cloth, and Nîmes a city in southern France known for textile manufacture. Said quickly and borrowed into English, “de Nîmes” became “denim.”

The companion word “jeans” tells the other half of the story. It derives from Gênes, the French name for the Italian port of Genoa, whose sailors and workers wore hard-wearing cotton trousers. The cloth associated with Genoa was called “jean,” and the garments made from the related Nîmes fabric eventually took the name “jeans.” So a pair of blue jeans quietly names two Mediterranean cities at once.

For a long time there was genuine confusion and overlap between the fabrics, but denim as we know it — a rugged cotton twill in which the blue warp threads show on the outside and white weft on the inside — proved ideal for workwear. In nineteenth-century America it was turned into durable trousers for miners and labourers, reinforced with rivets, and the modern blue jean was born.

From the mills of Nîmes to the gold fields of California and then to wardrobes everywhere, denim became perhaps the single most recognisable fabric on earth. Its name remains a small geography lesson, carried in every pocket and seam: a cloth that never forgot where it came from.
