Pants that marked the aesthetic culture of the second half of the 20th century. In addition to their practicality, they represented and continue to represent a symbol (although changeable over history) from workers’ uniform or the uniform of youth protests, from rebel to pop, to passé partout without age or role limits. They can be basic or interpreted according to a style, in traditional indigo or colored, faded, marbled, stone-washed, torn, or starched. Every decade creates its favorite list, preferring a certain type of finishing, color, or style. Worn with a blue blazer is the informal uniform of businessmen, whereas a baggy version is the favorite garment of the rap rebellion. The fabric is similar to denim (from NÑmes) — it actually has the same Levantine structure (diagonal lines, front different from the back) — but it is lighter. Created in Genoa. It is a highly resistant, light fustian, from Genoa, actually called jean or jeane. It was present in the market since the Middle Ages, but its transformation into working trousers dates back to the 1800s, when it was used by longshoremen. It was only from 1850 that the term jeans was used to identify not the fabric but a model. In San Francisco, Levi Strauss, with his partner Jacob David Youphes, launched a model of resistant trousers with five pockets for the gold-diggers. After approximately a century, from the 1840s to 1900s, jeans became a trendy garment, first in the USA and then in Europe. In the late 1960s, during the outbreak of the hippy movement, they were the common denominator of rebellion. With the passing of time, jeans have changed models and their manufacturing techniques, following the temporary rules of designers’ fantasy rather than political ideologies. As well as the historical Levi’s, two other jeans manufacturing companies represent the identification between a clothing piece and a brand: Lee and Wrangler.
