Measuring for bra size

Determining the correct *bra size* (also known as *brassiere measurement*
or *bust size*) is the process manufacturers engage in to design and
manufacture bras that correctly fit a majority of women, and for individual
women, the process of identifying a correctly fitting bra.^[1] Bra sizes
usually consist of one or more letters indicating the breast cup size and a
number, indicating a band size around the individual's torso. Bra cup sizes
were invented in 1932 and band sizes became popular in the 1940s.

The shape, size, position, symmetry, spacing, firmness, and amount of
sagging of individual women's breasts vary considerably. As a result, about
25% of females have a difficult time finding a properly fitted bra. Some
women choose to buy custom-made bras due to the unusual size or shape of
their bust.

Manufacturers mass-produce bras as ready-to-wear garments and size them to
fit standard, idealized, female torsos. Manufacturer's bra size labeling
systems vary from country to country because no international standards
exist. Even within a single country, one study found that the bra label
size was consistently different from the measured size.^[2]
