How do girls measure their chest circumference

First of all, you should relax yourself naked, and use a tape measure to circle the protruding roots of your breasts. The measured size is your lower bust.

Next, talk about the size of the upper bust. Everyone should pay attention to this. In different situations, the measurement methods are different. I will introduce the differences one by one.

If your body is thin, you don't have much fat. You have to lean forward 30 degrees at this time. Then, measure the upper bust around the nipple with a tape measure.

If your breasts droop, you should gently lift them to the right position and then measure them, so that you can get the correct size.

If you have a lot of fat on your body and back, you should lean forward 45 degrees and measure it with a tape measure. The result is correct. I attach a picture for your reference.

Above, we know a measurement process of upper bust and lower bust, so how do we know how big a bra we want to wear? It's actually quite simple.

Just subtract the upper bust from the lower bust, and this value is the cup level.

Let me explain the calculation of this difference in detail.

Upper bust-lower bust value:

7.5cm AA cup,

10cm cup,

12.5cm B cup,

15 cm C cup,

17.5cm D cup,

20 cm E cup,

22.5 cm f cup

You can see that these figures have increased by 2.5 centimeters.

The size of the bra is = lower bust size+cup size.

Everyone seems to be a mathematical formula, but it is actually very simple. Let me give you an example:

For example, if your upper bust is 86cm and your lower bust is 74cm, then your bra size is 86-74= 12cm, and 12cm is just similar to the B cup, so you should choose the B cup. Then your lower bust is 74cm and 75cm. The final result should be 75B.

If you have special circumstances to be flexible, such as your cup level is between B and C, you should choose the C cup. Try not to choose a small one, it's bad for your chest. Because, in different countries, if some people buy foreign brands, the size of natural bras is different.
