First, X is one of the clothing size codes. For example, XL, XXL, XS, etc., stand for extra (special), XL: extra large (extra large), XS: extra small (extra small)

XL: extra large (extra large).

There are two ways to mark the size of common clothing:

One is S (small), M (medium), L (large), XL (extra large);

The second is the form of height plus chest circumference, such as 160/80A, 165/85A, 170/85A, etc. The first marking is not standardized. Whether it is domestic or imported clothing, the model must be marked according to China's clothing model standard GB/T1335, and English letters can only be used as auxiliary codes.

So the xl size is larger.
