Fewer jeans were made during World War II, but were introduced to the world by US soldiers, who sometimes wore them off duty.
By the 1960s, both men’s and women’s jeans had the zipper down the front. Historic photographs indicate that in the decades before they became a staple of fashion, jeans generally fit quite loosely, much like a pair ofbib overalls without the bib.

Michael Belluomo, editor of Sportswear International Magazine, Oct/Nov 1987, P. 45, wrote that in 1965, Limbo, a boutique in the New York East Village, was “the first retailer to wash a new pair of jeans to get a used, worn effect, and the idea became a hit.” He continued, “[Limbo] hired East Village artists to embellish the jeans with patches, decals, and other touches, and sold them for $200.
In the early 1980s the denim industry introduced the stone-washing technique developed by GWG also known as “Great Western Garment Co.” Donald Freeland of Edmonton, Alberta pioneered the method, which helped to bring denim to a larger and more versatile market. Acceptance of jeans continued through the 1980s and 1990s. Originally an esoteric fashion choice, in the 2010s jeans may be seen being worn by people of all genders and ages.
