In people's impression, the classic jeans should be like this: indigo blue, pure cotton twill, tight hip, low waist and short crotch design, slightly smaller trouser legs, buttons, stitching, patch pocket, nails and other decorations. However, the earliest jeans were not what we thought. Levi's, the originator of jeans, introduced 50 1 jeans, which can be said to be a classic of jeans. Let's review the evolution and development process of jeans from birth to classic:

1855- The earliest jeans had only one back pocket and no York.

1872—— It is the first time to reinforce the stressed parts of jeans with metal rivets.

1873- Jeans changed from gray to indigo. The back pocket is decorated with orange double arch stitches.

1886- changed the pattern of waist tag from dwarf to horse.

1890- plus a watch bag and a back York.

1905- With the second back pocket, jeans are fixed in the form of five pockets.

1922- Add a belt loop at the belt.

1937- The rivet in the back pocket is hidden inside.

194 1 year-the rivet on the lower part of the front placket of jeans was cancelled. During World War II, the bow of the back waist and the rivet of the watch pocket were removed, and the double arch seam of the back pocket was replaced by a printed similar pattern. A laurel leaf replaced the sign of "l. s&"; Company terms.

1947- Arched suture reappearance.

1950- In order to keep up with the fashion trend, the trouser legs were cut into thinner styles.

1955- Start production of 50 1 zipper jeans.

1959- Pre-shrunk jeans developed.

1966- Fix a short strip trace instead of a rivet at the corner of the back pocket.

197 1 year-the red sign was changed from "Levi's" to "Levi's".

1983- due to the improvement of loom technology, the width of the door is widened and the red hem disappears. In the 1990s, with the rapid development of science and technology, the technology of making jeans has been greatly improved, and with the accumulation of time, jeans have today's perfect structure.
