The most difficult thing is to correctly determine the size of the bra. To do this, find out the volume under the chest and chest. Here many of us are mistaken because they do not take into account the nuances. But in vain! Then we wonder why the bust falls out of the cups or the bones “climb” onto the chest, press and rub.

How to determine breast size?

  • If you have a small elastic chest, stand up straight and measure the chest girth and under the chest with a measuring tape.
  • But if the breast is saggy, you have to bend down to determine the volume of the chest. Bend at an angle of 90 degrees and use a measuring tape to measure your bare breasts at the most prominent points.

It turns out two digits. One more is the girth of the chest, the other is smaller – the girth under the chest. Now is the time to determine the size of the bra cup.

Subtract the smaller from the larger value. For example: 88 cm – 72 cm = 16 cm. This figure indicates the size of the cup, in this case, size C (3).

See the table to determine your bra cup. Here the logic is simple: the size range steps every 2 cm.
