Its important that she does not go into this with the wrong expectations. That is the main reason why people regret their breast augmentations.

The first step is to properly identify why she wants to do this. Maybe its small breasts or maybe they dont look good, but whats wrong with it? Several of the most beautiful women in the world are less endowed in the chest department. In addition the only one who should see them is her partner. Getting a breast augmentation can sometimes be worse for intimacy, because it removes some of the vulnarability of being naked.

For the purpose of boosting self-esteem, breast augmentations are really hit-or-miss. They work for some people, but for most it would be better (and way cheaper) to rationalize their issues.

The two main reasons for getting a breast augmentation (and being happy with it) is either that you want that shallow sexual attention a pair of bigger titties will get you (which gets weird fast when you are in a relationship with someone who don't care for it), or that you want a wider selection of dresses that just fit well around the chest.

Another thing to consider is that the bigger implants you get, the more likely you are to get back issues. Most of the people I know who have been happy with their breast augmentations has been girls who are into fitness. They never got any back issues from it because they chose modest implants, and have both the strength and posture to avoid any back issues. On the other side I know a girl who ended up in quite serious debt after having a reduction because she couldnt handle the back pain.

All this said, I love fake boobs because I love the kind of girl who would get it to get more sexual attention from random guys. It always saddens me when I find out they got them for any other reason, because more often than not, they regret it.
