The contoured form of a Coca-Cola bottle was inspired by the rounded form of a cocoa bean. Similarly, “Coke bottle body” or “body like a Coke bottle” refers to the curvy physique of a woman whose breast and hips are around the same size.
A “Coke bottle body” is synonymous with an hourglass physique. A woman with an hourglass figure, also known as a butternut squash or figure-eight figure, has a bust and hips that are roughly the same size and a waist that differs from either of these measurements by no more than 10 inches. Marilyn Monroe, whose dimensions were 37-22-35, is a notable example of a lady with a Coke-bottle figure.
