Young Teen College Girl Without Brassiere

• No manufacturing standards
Manufacturing a well-fitting bra is a major challenge for companies, since the garment is supposed to be form-fitting, but the size and shape of women's bodies and breasts vary widely. Manufacturers make standard bra sizes that provide a "close" fit, however even a women with accurate measurements can have a difficult time finding a correctly fitted bra because of the variations in sizes between different manufacturers.
• Variance in bra sizes
There are several sizing systems in different countries. Most use the chest circumferences measurement system and cup sizes A-B-C+, but there are some significant differences. Most bras available usually come in 36 sizes, but bra labeling systems used around the world are at times misleading and confusing. Cup and band sizes vary around the world. For example, most women assume that a B cup on a 34 band is the same size as a B cup on a 36 band. In fact, bra cup size is relative to the band size, as the actual volume of a woman's breast changes with the dimension of her chest. In countries that have adopted the European EN 13402 dress-size standard, the torso is measured in centimetres and rounded to the nearest multiple of 5 cm.
