The frame size is the firm circumference directly underneath the breasts.
The bust size is the loose circumference around the chest over the fullest part of the breasts, while standing straight with arms to the side and wearing a properly fitted bra.
Surveys and studies showed that more than 70% of women in the world wear incorrectly fitted bras. The most common issues are the too large cup size and too small band size. Signs of incorrectly fitted bras include band dig into the torso, red marks, pain in the shoulders or neck, the band sliding up, the breasts overflow from the edge of the bra, the bra's center panel does not lie flat against the breast, etc.
The two major sizes for a bra are the band size and the cup size.
Band Size (Frame size)
The band size is the size of the bra band around the torso. Band sizes vary in different counties.
