Generally speaking, the size S of clothes is the smallest, and S stands for "small", so the number marked is the smallest. In the national standard GB/T 1335, the size of blouse S (small) is155/80a; The size m (medium) is160/84a; The large size is 165/88A.

"Size" refers to the length of clothes, and "type" refers to the thinness of clothes. For example, 165/88A, the numbers before and after the diagonal line indicate the height of the human body and the bust or waist of the human body, and the letters after the diagonal line indicate the physical characteristics of the human body.

The basic principle of all clothing measurement is the same, but the measurement method will be slightly different for different customers.
