A:

First of all, stand in front of the mirror to make sure the tape measure is straight. You measure the underbust size just below the breasts. It is important that you do not have the tape measure too tight, but also not too loose. the size of the underbust size is shown in centimeters, and this indicates the size of the chest strap.

B:

To calculate the correct cup size, measure on the fullest part of the breasts. This is often at the level of the nipples. Again, it is important that you do not keep the measuring tape too tight, but also not too loose.

You just measured the underbust size. Now it is time to see which one comes closest. There is a tolerance of 2.5 cm on the circumference size. If you measure 81 cm, your girth size is 80. If you measure 88 cm, your girth size is 90.

To calculate the correct cup size, calculate the difference between the circumference size and the bust size.

With a difference of 10 to 12 centimeters between the circumference size and the chest circumference, it is a cup size A. With every 2 centimeters more, it is an extra cup size. Look in the table on the right.
