Underwear size classification:
Underwear sizes are generally replaced by letters, which are divided into A, B, C, D and E cups. A cup is the smallest, and so on, E cup is the largest, and it is a special model that exceeds E cup, which is relatively rare.
These English letters are graded every 2.5cm, and the minimum AA is 7.5cm. Based on this, Cup A is 10cm, Cup B is 12.5cm, Cup C is 15cm, Cup D is 17.5cm, and Cup E is 20cm.
Judgment method:
There is a complete set of calculation methods to judge what kind of underwear you wear. The result of subtracting the bust size from the bust size is the size of the cup. By comparing the obtained value with the underwear size comparison table, you can know which size underwear you are most suitable for.
