How many pieces of cloth does a pair of jeans consist of?

A pair of jeans usually consists of about 20 pieces, depending on the design.

The outer seam of traditional jeans is straight, and the angle of the hem is also straight. Only the inner thigh, front and rear gears, front and rear midline, York and waist can shape the outline. Generally, the width of wide denim is about 150 cm, while the width of narrow denim is only about 86 cm, so jeans of the same size, if made of narrow denim, are almost twice as long as wide denim, that is, they will use more materials than wide denim.
