The following is an introduction to dimensions:

According to the relevant national standards in China, the clothing sizes of adult men and women are expressed by the size system. In addition, the labeling methods we usually see, such as S, M, L (usually used in casual wear), or 27, 28, 29 (usually used in pants), or 44A, 44B, 46A (usually used in suits), are not standardized, but everyone is used to it.

Adult men's and women's clothing sizes include size, body shape and body shape. Among them, "number" represents the height of the human body (expressed in centimeters with a step size of 5 centimeters); "Type" refers to the body's net chest circumference (top, generally 4cm for a file) or net waist circumference (bottom, generally 4cm for a file); "Body shape" refers to the difference between net chest circumference and net waist circumference.
