Bra cup size comparison chart
Size of the cup = upper bust - lower bust

AA cup: within 7.5cm

A cup: 10.0cm or less

B cup: within 12.5cm

C cup: within 15.0cm

D cup: within 17.5cm

E cup: within 20.0cm

F cup: within 22.5cm

For example, if the upper bust is 90cm, the lower bust is 75cm, and the difference between the two numbers is 15cm, then use the C cup, and the bra that should be worn is 75C.

Most of the underwear sizes on the market are generally underbust size/cup size, such as 70/A, which means that the underbust is 70cm and the cup is A-shaped.

Most of the size standards for the lower bust are in two sizes, one is the Japanese size (such as 70, 75, 80), the size difference of each model is 5cm, and the other is the European and American size (such as 32, 34, 36), the size difference of each model is about 2.5cm. The algorithm of the cups is very uniform, using ABCDE...... to indicate how big it is.
