The key aesthetic elements are nipple position and the proportion between the upper and lower halves of the breast, cosmestic surgeon Patrick Mallucci said.
"The ideal is a 45 to 55 per cent proportion - that is the nipple sits not at the half-way mark down the breast, but at about 45 per cent from the top."
He added: "All of the models I looked at conformed to these parameters. None of them were augmented and yet they were clearly considered to have beautiful breasts, so I wanted to examine how that could be achieved in someone not so well-endowed by using an implant.
"It's about wanting to create something as close to perfection as possible."
Mr Mallucci said the best breasts belong to the model Caprice Bourret - a view shared by many of his clients.
He added that said patients frequently begged him not to make their breasts the same shape as Victoria Beckham's "unnaturally round" globes.

I'm not sure who this Caprice person is, but I would have to agree with the findings.
