The word "denim" comes from "serge de Nîmes", a fabric made in Nîmes, France, and "blue jeans" comes from "Bleu de Genes", blue pants made in Genoa (aka Genes). Both cities claim to have been manufacturing denim for centuries, but there has never been much proof in the way of artifacts and such. So the recent discovery of several paintings from the mid-1600s depicting people wearing jeans is surprising and exciting. Look at this jean jacket. Classic in the deepest sense!
