A wide variety of corrective breast surgeries can be performed, and not all of these are necessarily cosmetic of nature:

It is said that men have honoured the female breasts in several ways: In a temple on the island of Rhodes a goblet was displayed, apparently moulded from the perfect breasts of Helen of Troy. King Henry II is said to have made casts made of the apple-like breasts of his mistress Diane de Poitiers, while Marie-Antoinette’s breasts are believed to have inspired the design of the French champagne coupes.

Whereas makeup can be used to hide an aging face to some degree, hiding aging of the neck and décolletage or chest area is difficult – unless you’re willing to wear scarves and polo necks across all seasons.
