The total wave length of trousers refers to the total length of the front waist midpoint passing through the crotch bottom to the midpoint of the back waist. In the design of the board, 75% or 73% of the waist circumference is gained by 10% of height. But this is not the only confirmation. The wave length also has something to do with the pants type, and it has something to do with the figure of the person. We will explain the height of the female "A" figure with a height of 160 cm. The waist length of the waist waist trousers is basically 66~67 centimeters, and the waist height is higher than the waist circumference of the human body. If it is low waist trousers, it will lose two times the amount of waist drop 12 centimeters, the waist length of trousers is 55 centimeters long. If you are doing waist free pants, you need to reduce two times 3 centimeters and the total wave length is 60 centimeters.


Therefore, even if there is no straight crotch size in the foreign trade process sheet, we can get the straight crotch height through the size of the total wave. In general, the total wave length of 1/3 plus 3~4 cm is equal to the length of straight crotch, and the height of straight crotch can also be increased by 0.5 centimeters before the wave. The length of the front wave is 40% to 45% of the total wave length, and the total wave length is shorter. The difference between the front and the rear waves is larger, with 11~12 centimeters, and vice versa.
