For example, with the size of 80D the measurement of the torso girth should be from 78 (cm) up to 80 (cm), the measurement of the breast cup size is from 98 (cm) to 100 (cm).
Determining the breast cup size:
In order to determine the breast cup size the chest girth measure is subtracted from the measure of the torso girth. The obtained number should be compared to the size chart.
Example of determining the size:
With the torso girth of 88 (cm) and the chest girth of 106 (cm) the cup size is 106 – 88 = 18 or C.
The final size is 90C.
Important: well chosen bra should feel comfortable,being fastened on the last hooks (loosest position).
Bras for pregnant and nursing women:
The measurements should be taken at the moment when the breast is maximally full with milk. The cups should be elastic, with a feature to change their size. It’s not recommended to buy foam bra models.
Important: different countries and producers have different bra proportions. For accurate model size determining the best way is trying the model.
