The word "cup" was defined by the French. Because the bra was invented by the French in the 1920s, its original name was corset. Bra is abbreviated as bra, which comes from French.
When the French invented the bra, they also determined the unit of breast or the breast size derived from it. The word cup is translated quite vividly in China, because apart from the belt, there are only two cups to cover the chest, and then the size of the breast is measured by the size of the cup, which is easy to understand.
The calculation formula of cup is: cup size = upper bust size-lower bust size.
The bra size comparison table is a bra size and bra size table based on international standards. The measurement standard is the length of a circle around the bottom of the breast horizontally, that is, the length of the chest next week, in centimeters (cm). Let's look at the bra size comparison table.

The length of a horizontal circle around the highest point of the chest (nipple) is your bust size. If you encounter decimals when measuring dimensions, it is recommended to adopt the progressive method, such as 72. 1 cm, and calculate it as 73 cm.
After getting the size of the upper and lower bust, start to calculate the size of the cup:
Subtract the upper bust from the lower bust to get the difference between the upper and lower bust. Through the following comparison table of girth difference cups, the most suitable cup size can be obtained.
