Many women have been wearing bras since adolescence, but they don't know much about this daily wear. So how are the sizes and models of bras determined, and what do various models mean? Let's have a brief look together today!

What do you mean by 1.a cup, b cup, c cup, d cup and e cup? The size of the cup lid is determined by its depth, which is determined by the bust at the highest point of the breast (one of the three busts) minus the length of the bust under the breast. Is a word to describe the size of women's bras, in which AA and A are the smallest two models.

Type AA =7.5 (the difference between chest circumference and lower chest circumference is cm)

A= 10 (the difference between chest circumference and lower chest circumference is cm)

B= 12 (the difference between chest circumference and lower chest circumference is cm)

C= 15 (the difference between chest circumference and lower chest circumference is cm)

D= 17.5 (the difference between chest circumference and lower chest circumference is cm)

E=20 (difference between bust and lower bust cm)

F=22.5 (the difference between chest circumference and lower chest circumference is cm)

G=25 (difference between bust and lower bust cm)

H=27.5 (the difference between chest circumference and lower chest circumference is cm)

I=30 (the difference between the bust and the lower bust is cm)

Second, the size of the cup: the size of the bra under the breast is calculated in centimeters, and some are calculated in inches.

Generally speaking, the bra size is lower than the bust size. The sizes of bras are 70, 75, 80, 85 and 90 respectively, instead of 32, 34, 36, 38 and 40.

Suppose: your upper bust is 85 cm and your lower bust is 70 cm. Then, the formula is used to calculate the type of cup to be selected, which is the upper bust MINUS the lower bust, which is equal to15 cm; ; Because 15CM corresponds to a C cup, you should choose C; At the same time, the size of the lower bust is 70 cm, so the bra size should be 70 models. Based on two points, it can be concluded that it is more appropriate for girls to wear a 70C bra.

What's the difference between 36A and 34A bras? As mentioned in the formula just now, 34 and 36 represent the lower bust, but the British standard is adopted; Can be converted into standard centimeters, 34A is equal to 75A, 36A is equal to 80A.

Simply put, the bottom circumference of 36A is one yard larger than that of 34A, which is equivalent to the bottom circumference ratio of 75A of international size 80A (36A is an English size).

In addition, it should be noted that the international standard size used in China is different from that used in Japan. The bottom circumference of Japanese small cup bras is one yard smaller than that of China, that is, the 34A worn by China is equal to that of Japan, and there is no difference between them. If you buy a Japanese brand, you should ask the customer service if there is any size difference.

The only difference is that the cup sizes are different. One is a cup, and the other is a cup. The letters represent cups, A cup, B cup, C cup ... refer to the size of cups. In alphabetical order, A cup, B cup, C cup, D cup, E cup and A cup are the smallest sizes.

The size of the cup is the difference between the upper bust minus the lower bust. Generally speaking, choose a cup around 10cm, b cup around 12.5cm, c cup around 15cm, d cup around 17.5cm, e cup around 20cm and f cup above 20cm.
