The calculation formula of cup is: cup size = upper bust size-lower bust size.

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.

A cup is less than10 cm; ; B cup is less than12.5cm; ; C cup is less than15cm; ; D cup is less than17.5cm; ; E cups are less than 20cm. A, b, c and d refer to your cups.

Your upper bust is 97 and your lower bust is 75, which can be obtained by the formula of cup size = upper bust size-lower bust size.

Cup size = = bust size-bust size =97-75= 12

I know your cup range is B, so I choose B cup.

Matters needing attention in measuring bra size

The calculated number of cups is not necessarily the size you should finally buy. There are three possibilities:

1, too much fat: choose a higher number of cups. (For example, when the difference is C, D is usually selected.)

2, the calculated difference is vague: you try to choose a larger cup model, so there is room for breast development. (For example, if the difference between C and D is 15, D is usually selected. )

3, the shape of the breast is flat as loose sand: the smaller the difference between the measurements, the greater the grade of the selected cup. (For example, if the lost fat is molded according to the scientific dressing method, the measured difference is the B cup, so the selected cup is the C cup).
