I personally hate fake boobs. I think it makes a woman look trashy. But that is just me.
If you want to do it for you then go for it. Just make sure you weigh out the pros and cons. They are not healthy.
I have big boobs and I will tell you what. I would take me a cup that I had in seventh grade anyday over large boobs. You cannot wear the cute shirts that small boobed girls can, finding a bathing suit that fits you is virtually impossible, they get in the way and are just plain awful.
But even when I had small boobs I never wanted big boobs, so I guess I just don't understand the whole paying someone to put you under the knife and enlarge the fat in your chest.
And on the other side of things, most men really don't care about your breast size as long as you are in good physical shape.
But good luck with whatever you decide.
