Small guide to not make a mistake, and buy well on the internet.

Knowing your cup size

First, you need to measure your bust size yourself with a tape measure. To then know your cup size, you must first measure your chest size from the tip of your breasts, then subtract your bust size from this number: – if the difference is 10 cm, you make an A cup. – if the difference is 15 cm, you make a B cup. – if the difference is 17.5 cm, you make a C cup. – if the difference is 20 cm, you make a D cup. – if the difference is 22,5 cm, you make a cup E. The right cup should be neither too big nor too small: your breasts should fill it correctly, without overflowing or showing your nipples.
