The hard wearing work trouser was thought to have been invented by a sail maker named Levi Strauss,

in San Francisco, in 1850.

It got its name from Jene Fustian- a heavy twilled cotton cloth as jeans.

The name denim comes from the French phrase Serge de Nimes (Serge of Nimes).

The name of the inventor Levi is also associated with the jeans.
