Additional measurement to calculate your bra size: Diameter of Underwire

Additional measurement to calculate your bra size:

Diameter of Underwire

1. You need to take the most perfectly fit underwire for your breast that you have and calculate its Diameter.

Figure 2 illustrates the correct way to do this. You must accurately fit your underwire into the circle and then determine its Diameter. The diameter of the circle obtained will be the Diameter of your underwire.

Figure 1 demonstrates how not to do it. The line connecting the ends of the underwire is NOT its Diameter!

2. Next, following the chart below you specify your cup size. 

For example: Diameter of your underwire = 123mm, according to the table, we understand that our cup size is 80А/75В/70С, as it falls within the range of 120-125mm.
