How come most women I know say fake breasts are awful, but so many women are getting them anyways?
Depends what kind of women they are.
Now, if it's for reconstructive surgery after breast cancer, that's wonderful! My best friend had that done after she lost both of her breasts to cancer.
But to do it to increase your sex appeal, well, some women feel more confident I guess getting bigger boobs, since you know that's what REALLY makes the person....
Just like a man getting a hair transplant or a rug to wear on their head to hide their baldness.
To each their own, but there are consequences to anything when you mess with nature!
