Speaking of jeans, people naturally think of 1849 gold rush in America. At that time, the first immigrants who set foot on the American mainland were poor and had to work hard. Strenuous labor makes clothes wear easily, especially in 1849, when miners flocked to California, which formed the famous gold rush at that time. Because cloth breaks easily, people are eager to have a durable dress. At this time, some factories use Genoa canvas to produce work pants, so they call that canvas Genoa canvas, which means "Genoese". Later, the trousers made of that canvas were simply called Genoese. Later, it evolved into "jeans", a kind of durable jeans. Levi's, a Jew, is recognized as the inventor of jeans.

1850, the 50 1 jeans produced by Levi's Company, which he founded, is the world-famous originator of jeans. In the mid-1930s, jeans, which were worn by almost everyone in the agricultural areas in the midwest of the United States, were first brought to the bustling cities east of the Mississippi River, and jeans began to enter the ranks of popular clothes.

During World War II, the American authorities designated jeans as uniforms of the American army, and a large number of jeans went deep into the hinterland of Europe with the allied forces. After the war, soldiers returned to the United States, and a large number of accumulated jeans were sold locally in limited quantities. These trousers are very popular in the local area because they are beautiful, practical, durable and cheap. As a result, local European overalls manufacturers are scrambling to imitate the original products of the United States, thus making jeans popular and popular throughout Europe. The film and television entertainment industry in Hollywood has played an important role in promoting the international fashion trend of jeans. In the famous movies during the 1950s, such as Rebellion for No Reason and Family Dream, the protagonists in the movies all wore comfortable and generous jeans. Under the influence of big-name stars who led the trend, jeans became the fashion symbol at that time. In 1960s and 1970s, the popularity of rock music and the influence of hippie lifestyle on teenagers made jeans more popular. At this time, jeans also entered the upper class, and aristocratic families competed to wear jeans. Among them, Princess Anna of England, Queen Fahd of Egypt, King Hassan II of Morocco, King Hussein of Jordan and former French President Pompidou all like to wear jeans. More dramatically, former US President Jimmy Carter also participated in the presidential election in jeans. Since then, the value of this humble denim suit has soared by a hundredfold, enduring for a long time.
