The difference between international sizes and Asian sizes was in the form of measurement, the measurement location, and the size range. International codes usually use letters (such as XS, S, M, L, XX, XXL) to indicate the size of clothes, while Asian codes use data such as height and waist circumference to determine the size of clothes. In terms of measuring body parts, international sizes were mainly based on chest circumference, waist circumference, and hip circumference, while Asian sizes included shoulder width, chest circumference, waist circumference, and hip circumference. In terms of size range, international sizes were usually XS, S, M, L, and XX, while Asian sizes were usually expressed in numbers, such as 155.80, 160.84, 165.88, and 170.92. It should be noted that due to the difference in the size system, there may be a size error when buying international brand clothing. The Asian sizes of European and American brands may be slightly larger than the actual size, while the European and American sizes of Asian brands may be slightly smaller than the actual size. Therefore, when choosing clothes, you should choose the size that suits you according to your body size and measurement standards to avoid uncomfortable situations.
