Specifications and models, also called clothing size standards, are a series of specifications that represent human body shape and clothing measurements. They are a set of measurement indexes formed to standardize manufacturers' production and facilitate customers' purchase.

The clothing size standard is based on the basic size of the human body, plus an appropriate amount of looseness according to different styles. Once the specifications and dimensions of clothing are determined, it becomes the basis for clothing manufacturing.

In some customers' size charts, in addition to the size, the main body dimensions are also marked. If necessary, you can determine whether the size is correct based on the body size. However, there is always a difference between the specification size of clothing and the actual manufacturing size, so the tolerance TOL (Tolerance) is given on the customer's size chart.
