How bra size is calculated?

It is estimated that 70-80 percent of women in the world wear the incorrect size of bra which ultimately results in shoulder pain, neck pain, red marks over the body, poor Body shape, and much more. Moreover, breasts are made of flexible muscles and tissues and if incorrect bras are worn for longer period breasts will start sagging and will become out of shape. So, it is very important to calculate bra size correctly and wear a perfectly fitted bra. Unfortunately, the data collection method by bra manufacturers varies from country to country and there is no standardization. For instance, a 36A bra from two different countries may not be of the same size because of varying standards. The woman also makes mistakes by selecting the wrong bra size. It is recommended to calculate your bra size and tries a bra before buying.Bra size depends on two measurements band or under bust size and bust size.
