Wow... not a single Rick Roll yet... This Clickbooth thing clearly has people agitated!
As for breast implants, from what I know about them (which is more than average, as I used to manage a bar that was a haunt for strippers before & after their shifts... and goths that would often wear less than the strippers), you're going to want to get a soft silica gel bag, that's filled with a saline/collagen compound.
They hang much more naturally.
Also, try to have them attached to the pectoral majora if at all possible. A lot of surgeons won't do it because it could damage the muscle long term
but once again, they will look more natural as your body shape changes due to addition / loss of muscle or fat.
i[]However[/i], I think you're better of just getting those fake inserts that you put under your tit to make them look bigger... Unless this really is because they're of a noticeably different size.
