Abstract: A breast measurement device and method of accurately measuring a bra for a woman by submerging the woman's upper torso in a body of water that allows the buoyancy of each breast to lift and re-conform the breasts to their natural shape. A scanning machine is then used to measure the woman's upper torso and the submerged, lifted breasts to obtain their exact size, volume and location which then can be used to select a properly fitting bra which holds and supports the breasts in their natural position. In the preferred embodiment, the system will include a transparent tank filled with water in which a woman sits upright. A scanning machine then moves around tank and aimed at the woman's upper torso and the breasts. A digital file is then created and stored that is then used to select a proper fitting bra.
