It is a set of measurement indicators formed to standardize manufacturers' production and facilitate customers' purchase. When buying clothes, you can look for the size of this dress in the clothes, or you can directly try whether the clothes fit.
If you can't find the clothes size, you can ask some shops. Size is directly proportional to height and weight, so you can try more when you buy it.
You can't just choose clothes according to size. Many people can't buy suitable clothes because they only look at the size and don't look at the specific data of the size parameters, because each brand/manufacturer has different definitions of specifications.
