There is no ideal or perfect shape for the navel of a woman

There is no ideal or perfect shape for the navel of a woman, regardless of her age. The shape of a person's navel is largely determined by their genetics, and it can vary widely from person to person. Additionally, there is no specific standard for what a "good" or "attractive" navel looks like, as beauty standards are subjective and vary from culture to culture. It's important to remember that everyone's body is unique and that there is no one "right" way for it to look.
