Clothes sizes are based on S (small), M (medium), L (large) and XL (large), and other sizes are increased or decreased. For example, 2X stands for xxl, 3x stands for xxxL and 4x stands for xxxxL.
For example, the common M code is suitable for people with medium height from 160 to 165, and the L code is suitable for people with high height from 165 to 170.
Of course, the size is chosen according to the corresponding height and weight, so everyone's weight and height are different, and the size chosen is different.
Men's 2XL is 185 and women's 2XL is 175.
4XL (extra large) is an extra large size.
Women's 4xl is one plus one size, which corresponds to height 185cm.
