Denim pants are dubbed "jeans" by the Baby Boomer generation. The name has its origins in the French phrase bleu de Genes (literally, "blue of Genoa"), and harks back to the first known uses of denim pants – as a uniform for Genoese sailors.
In 1961, the Denim Council's efforts paid off with a major public relations coup: the newly-formed Peace Corps allowed its first 200 volunteers to wear jeans. This ushered in a new era across the board. It was a brave new world of positive revolution, rock-and-roll and, to bring the topic full circle, women's rights.
1970s
When Vogue featured blue jeans on their cover in the early 1970s, denim received its official sartorial sanction.
1980s
In 1988, as Anna Wintour picked up the reins as Editor of Vogue, her very first cover featured a young model wearing a $10,000 Christian Lacroix shirt matched with a pair of Guess (?) blue jeans. The message conveyed was that jeans can hold their own in the world of high fashion.
