The two major aspects of bra size are the band size and the cup size.
The band size is the size of the bra band around the torso. However, band sizes come in different measurements in different countries, in that sizes such as small, medium, and large, equate to different measurements. Refer to the table below for some size measurements, though some variation from the published measurements is possible.
