You might be interested in the origins of "denims".
The original cloth design was French.
The city of Nimes in France was famous for many years as a center for cloth production.
Their unique fabrics were "from Nimes" (De Nimes in French).
Once in America, De Nimes was changed to DeNimes and then to Denims.
The cloth was not very popular until the California Goldrush.
It was very strong and durable. The miners needed strong, durable clothing and tents for their prospecting work. Denim was perfect.
The Levi Strauss family in San Francisco somehow convinced America that this utilitarian cloth from the mining industry could also be a fashion statement.
Now we have miner's uniforms being worn as formal wear on cruises.
