Clothing size standard is based on the basic size of human body, according to different styles, plus appropriate looseness. Once the clothing size is determined, it is the basis of clothing manufacturing.
In the specifications of some customers, in addition to the specifications, the main body size will also be marked. If necessary, you can judge whether the size is correct according to your body shape. However, there is always a difference between the clothing size and the actual manufacturing size, so TOL (tolerance) is given on the customer's size table.
