British researchers believe they have discovered the perfect breast shape, according to a study published in the Journal of Plastic and Reconstructive Surgery.
The study's authors surveyed 1,315 people (men, women, and plastic surgeons), asking them to look at photos of different breasts and pick the proportions they liked best.
Results were analysed according to population demographics as well as effects of age, sex, nationality, and ethnicity. The responses of 53 plastic surgeons were also included.
The winning 'ratio' across all three groups was 45:55 - as in 45% of breast tissue falling above the nipple line and 55% below it.
The study said that the 45:55 ratio "has universal appeal in defining the ideal breast."
This showed that all three groups of respondents preferred a 'natural shape' - similar to that of the Venus de Milo, the 150 BC statue thought to represent Aphrodite, the Greek goddess, on show in Paris at the Louvre Museum.
Different to, it would appear, the orb-like shape made famous by TV show Baywatch from the 90s.
Study hopes to provide template for breast surgery
Rather than just being an exercise in idle daydreaming, however, the survey did have a noble objective.
The idea behind the study was to help plastic surgeons have a more consistent, universal template for breast implants and reconstructive surgery for patients who have suffered breast cancer.
The study proposed that "this (45:55) proportion should be used as a basis for design in aesthetic surgery."
