1. Measure waist circumference: buckle the trousers and lay it flat, align the 0 mark at the left end of the trousers, measure the distance behind the right end of the trousers horizontally, and multiply the obtained data by 2 to get the waist circumference value.
2. Measure hip circumference: starting from 9cm above the cross of the trousers, measure the distance to the edge of one of the trouser legs, and then measure the distance to the edge of the other trouser leg. The overall measurement is in the shape of a letter “v”. Add the sum of the distance values and multiply by 2 to get the hip circumference value.
3. Measure the front wave: Vertically measure the distance from the edge of the trousers above the button to the cross position of the crotch, and the value of the front wave can be directly obtained. The front wave is used to distinguish between low and high waist pants. The larger the front wave, the higher the waist of the pants; the smaller the front wave, the lower the waist of the pants.
4. Measuring the back wave: Spread the pants flat, measure the distance from the waist edge of the back of the pants to the cross position of the crotch vertically, and write down the data directly as the back wave value.
Okay, my friend knows how to measure the pants size.
