Now-a-days you have millions of different options when it comes to breast implants. I know a woman whose breasts are filled with string behind the muscle so that they can never "pop".

If you decide to get an implant that is no more than two sizes larger than your natural breast, and they are capable of placing it behind the muscle it should look and feel much more natural.

The procedure is very difficult though and extremely painful.

A friend of mine had her breast increased from a large A to a normal C and it was near impossible to tell they were fake by simply looking at it. I never felt them, so I can't say personally if they felt natural, but she and her husband didn't seem to mind. She had the normal operation.

One thing about breast implants is that you will likely not be able to breastfeed, though some women do, some women's implants will break due to the baby's sucking. Also they have to be "touched up" every 7 to 10 years.

Even fake boobies sag!

Hope this helps!
