Bra model consists of bra size and cup size. Generally speaking, a woman's bust refers to the length of a circle around her breast along her nipple. The bra size refers to the female lower bust, that is, the length of a circle around the breast along the root of the female breast.
The cup size refers to the difference between the female bust minus the lower bust, that is, the cup size = bust-lower bust.
Generally, cups are represented by capital English letters such as A, B and C.. Every 2.5cm is a grade, AA is at least 7.5cm, A is 10cm, B is 12.5cm, C is 15cm, D is 17.5cm and E is 20cm.. Further up, it is considered to be a special size.
Extended data:
Cups are as big as shoes, and different countries and regions have different regulations. In addition to national standards, China also has international common sizes and American sizes.
First, the current European and even international bra size standards have the following advantages:
1. The measured lower bust is directly used as the first part of the size representation.
2. The order of cups is strictly in alphabetical order.
3. The grading of cups is more detailed.
International general bra size calculation method;
First, the bra size can be calculated by substituting the measured lower bust and bust into the following formula:
Lower bust+1 1? cm +？ n？ × 2? Cm = bust.
Cup? n？ = (bust? Lower bust? 1 1) / 2;
Where are the numbers? n？ Represents a cup (A= 1, B=2, C=3, etc.). For example, the difference between the bust and the lower bust is 15? Cm (n=2) stands for b cup.
Secondly, there is an American bra size, which is different from the international common size.
American bra size standard can be traced back to 1930, which is the oldest standard, but its classification is not detailed enough, and it faces big breasts or even super big breasts. The representation of cups is not unified and confusing. The biggest disadvantage is that the calculation of cup varies according to different manufacturers.
Calculation method of American bra size;
1. Is the lower body measured in inches? ( 1? Inches = 2.54? Cm)
2. Add 5.5 inches and round to the whole number (sizes 34, 36, 38, etc. )
The bust is measured in inches.
4, the size difference as a cup (≤ 1 inch = A, ≤ 2 inches = B, ≤ 3 inches = C, etc. )
take for example
Lower bust: 30 inches (76 cm), 30 inches +5.5 inches = 35.5 inches, and the lower bust size is 36 inches.
Upper bust 35.5 inches (90 cm)35.5? 36 = -0.5; It's a cup;
So the size of American bra is 36? A (bra size). The corresponding international standard size is expressed as 75? b？ (It is worth noting that not all American manufacturers use 5.5 as the added value, but it is usually between 3 and 6 inches).
