First, relax naked and stand up straight (you can measure it after taking a shower), surround the protruding root of the breast with a soft ruler and measure the size of the lower chest circumference. Then the upper body leans forward 30-40 degrees, surrounds the body with a soft ruler, and reads the chest circumference through the positions of the two nipples. The difference between the upper bust and the lower bust is the number of cups, which together with the size of the lower bust is the size of the bra.
The correct way to wear a bra is as follows: first, put the shoulder strap through your arm and put it on your shoulder.
The upper body leans forward slightly Hold the bottom edge of the bra steel ring with both hands, and gently move from the belly and abdomen to the protruding root of the breast, so that the breast is completely inserted into the cup. Then, slide your hands back along the bottom edge of the bra and fasten the hook.
Lean forward 45 degrees, hold the lower part of the steel ring with one hand, and put the other hand into the cup to transfer the fat lost from the back and armpits into the cup.
Adjust the shoulder strap and check whether the back position of the bra is under the scapula and whether the front position is in the middle.
Calculation formula:
The lower circumference is from 65 cm to 100 cm.
Bra size = bust size+cup series
Number of cups = upper bust-lower bust
Cup series reference:
When the difference is less than 9cm, bra cup A is selected.
When the difference is more than 9cm and less than 12.5cm, choose the B cup.
When the difference is greater than 12.5cm and less than 17cm, the bra cup is C.
When the difference is greater than 17cm and less than 20cm, the bra cup is selected as D cup.
When the difference is more than 20cm and less than 23cm, the bra cup is E cup.
When the difference is more than 23cm and less than 26cm, the bra cup is F cup.
When the difference is greater than 26cm, the bra cup is a G cup.
Selection of bra model
Women choose bras according to their bust size, such as 38 and 42, but they always add a letter such as ABCD to indicate cups.
Excuse me, how to choose a cup that suits your body shape?
How to choose a model when buying a bra?
The following is the calculation method of bra size:
When choosing a bra, we should basically pay attention to two dimensions, one is "bust" and the other is "cup".
Chest circumference = the number before and after horizontal winding through the highest point of the breast.
Lower bust = front and back bust measured horizontally through the lower edge of the breast.
Cup = bust-lower bust
Most underwear sizes in the market are generally marked with lower bust/cup size.
The size, such as 70/A, means that the lower bust is 70cm and the cup is A-shaped.
There are two standards for the size of the lower bust. One is Japanese size (such as 70, 75, 80), and the difference between each size is 5 cm; Second, European and American sizes (such as 32, 34, 36), the difference between each size is about 2.5cm.
The algorithm of the cup is very unified, and its size is represented by ABCDE.
As for ABCDE ... Here's the thing:
Subtraction of upper and lower bust difference of cup
AA cup below 8cm
A cup of 9- 1 1cm.
B cup11.5-13.5cm.
C cup 14- 16cm
D cup 16cm or more.
E cup 20cm
22.5 cm
For each additional cup+2.5cm,
The above F Cup can only be seen in Japanese movies, haha ~
At present, the size of bras on the market is a combination of numbers and English letters.
For example: 32B, 34C
What does this mean? The number part refers to the size of the lower bust, and the English letters refer to the size of the cup.
What is the bust represented by (1) 32C?
Most people may think that since it is 32C, it is good to directly convert 32 inches into centimeters.
That is, 32x2.54 = 81.28cm.
No! This is actually a very fuzzy algorithm.
If we can know from the bra size conversion table above,
32C refers to the lower bust of 68~72 cm and the upper bust of 86~88 cm.
So if you don't use the look-up table method, how to calculate it?
Let me teach you,
First, 32 of 32C represents the size of the lower bust, which is converted into 81.28cm..
What is the lower body?
8 1.28 cm, we use 82 cm to calculate, which is actually the bust of a cup.
A cup is the difference between the upper bust and the lower bust of 10 cm.
Therefore, the lower bust can be obtained by the following formula:
Lower bust = 82- 10 = 72 cm.
Check the conversion table, because the bra size is fixed, so the calculation is correct in the range of 68~72 cm.
What is the upper bust?
C of 32C represents the size of the cup, which means it can be used to calculate the size of the upper bust.
C cup is the difference between the upper bust and the lower bust of 15 cm,
Therefore, the upper bust can be obtained by the following formula:
Upper bust = 72+ 15 = 87 cm.
Check the conversion table, and the calculation is correct within the range of 86~88 cm.
(2) What is the bust represented by the label B75 on the bra?
This is the difference in specifications. 32C adopts the American algorithm, that is, 32 is inches.
B75 uses the Japanese (and Taiwan Province) algorithm, that is, 75 is cm.
But cup sizes, that is, B and C, are converted in the same way.
If you look up the table, you will know.
B75 refers to the lower bust of 73~77 cm and the upper bust of 89~9 1 cm.
If you want to use calculation, because it is metric,
So 75 of B75 is the size of the lower bust. Please note that the difference here is that,
75 cm is the size of the lower bust.
What is the upper bust?
The same is the size of the lower body plus the cup.
B cup is the difference between the upper bust and the lower bust of 12.5 cm,
Therefore, the upper bust can be obtained by the following formula:
Upper bust = 75+12.5 = 87.5cm.
Compared with the conversion table, there is a certain error in the range of 89~9 1 cm. But the cup algorithm has a little range, and B is also divided into B-, B, B+, so this algorithm is correct.
(3) Both 32c and 34C are CCCUP. Why do they look different?
This statement sounds strange, because they are all C cups, that is, the difference between upper and lower bust 15 cm. Why do they look different? (Note: It's just visually different in size, heh ~ it may feel different in size ~)
In fact, this is reasonable, and we can get it directly by looking up the table:
32C The lower bust is 68~72 cm, and the upper bust is 86~88 cm.
34C The lower bust is 73~77 cm, and the upper bust is 9 1~93 cm.
Imagine why. In fact, simply speaking, the difference between 32C and 34C is 2 inches, about 5 cm, and the difference between upper and lower bust is 5 cm. Of course, the visual effect is much worse!
3): The following is the relationship between female bust size and height ratio in domestic medical field.
Relationship with height: height ×0.53
The results are as follows:
≤0.49 is too small
=0.5-0.53 standard
≥0.53 Beautiful
& gt0.6 is too big
