"Size" generally refers to the size of clothes, the size of clothes, shoes and socks, and the length and size of some parts of the human body.

There are two types of ordinary clothes: one is S (small), the other is M (medium), and the other is L (large) and XL (large). The second is the form of height plus bust, such as 160/80A, 165/85A, 170/85A, etc. The first label is not standard. Whether domestic or imported clothing, models must be marked according to China's clothing model standard GB/T 1335, and English letters can only be used as auxiliary codes.
