as everyone said, it is about what you want, and not others. my husband (then boyfriend) didn't want me to get implants, and i knew most men didn't like them, but i didn't care, i did it for myself. i didn't like the look after 2 yrs of breastfeeding. small tops (i live in florida, and it is a year round thing) just didn't fit right, and you have to wear a bra or it looked trashy, IMO saggy bewbs just weren't what i wanted.
i never thought i would get them, but after breastfeeding i changed my mind. shallow? whatever. i certainly could have used the money for something more productive, but at the time i had money to burn so it wasn't an issue. i don't think i would make the same decision now, though. with a family to take care of and other concerns, i am more responsible with my finances.
