Cup size = bust size-bust size.
Measurement of upper bust size: the length of a circle horizontally around the highest point (nipple) of the chest is the upper bust size. If there is a decimal point when measuring the size, it is recommended to adopt the progressive method, for example, 72. 1 cm, and the calculation is 73 cm.
The difference is about 10cm, a cup is about 12.5cm, c cup is about 15cm, d cup is about 17.5cm, e cup is about 20cm, and f cup is above 20cm.
Extended data:
The following states indicate that the selected cup size is incorrect:
One, if the breast overflows from the upper part of the bra.
Second, the bra straps get stuck in the skin.
Third, the bra shoulder strap is stuck on the arm.
Fourth, the bra feels particularly tight, like it can't breathe.
Fifth, the bra is too loose, no matter how it is adjusted, the shoulder strap will fall off.
Six, can comfortably put two fingers into the bra edge and shoulder strap.
Usually, we should measure at least once a year to make sure that we are wearing the right size bra. There are many reasons for the change of chest size, whether it is because the body is still growing, or because it is obviously thin or fat, or because it is pregnant. If you want to wear a bra of the right size and wear it correctly, this is a good habit that should be adhered to.
