When Were Blue Jeans Invented? These Paintings Suggest the Fashion Trend Dates Back to the 1600s

Ten paintings attributed to the “Master of the Blue Jeans” depict Italian peasants wearing the storied fabric

The painter’s oil canvases depict early iterations of the stiff blue fabric beloved today, as worn by Italian peasants. According to a statement, the pieces have proved to be important artifacts in garment history, “pushing back [blue jeans’] provenance by centuries.”

“Jeans come from Genoa, while denim comes from the French city of Nîmes,” says Canesso.

Blue jeans were made with perpendicular stitches in northwest Italy, while denim was woven in chevron patterns in southern France.

But the key component of the fabric’s history is its coloration.

“Until the 11th century, no one could wear blue fabric because they didn’t know how to make blue color adhere,” Canesso says. “Only in the year 1000 did this begin to happen using woad leaves, and at a very high cost. The genius of the Genoese was to find the indigo stone in India and make this an industrial and therefore low-cost process.”
