Well, it depends what she wants the silicon for. If she wants it to get bigger breasts, there is already a cheaper fix, as illustrated by this anecdote:
The husband and wife were in the bedroom, ready to retire for the night. The wife was gazing at her contours in the mirror.
"Honey," she said, "wouldn't you like it if I had bigger boobs?"
"Well, poodle-cakes," he said diplomatically, "I didn't marry you for your physical attributes, I married you because I love you"
The wife said "But what if I could have a boob job done for a reasonable price?"
"Oh," said the husband, "I wouldn't complain, but I must stress it isn't that much of a deal to me. How much is reasonable?"
"Eight thousand pounds," said the wife.
"Good lord," said the husband, "that is outrageously expensive. Anyway you can get bigger boobs for almost nothing. All you have to do is rub some toilet-paper between your breasts every morning and your breasts will soon get bigger."
"Don't be silly," said the wife, "that will never work."
"I reckon it will," said the husband, "after all it worked for your bum."
