Looked real good, however she had huge scars underneath them. She said that silicone is better and thats the only way to put them in is under the tits, whereas saline can be deflated and inserted through the bellybutton or armpit. My question to you V boarders is, why the fuck would someone get fake tits if they are going to have 2 inch scars under their breasts 
From what I have been told... Both silicone and saline can be put on top of the muscle or underneath it. However, some doctors refuse to do one or the other.
The advantage of silicone is that it doesn't ripple. However, the disadvantage is that it's roughly 30-40% more expensive.
As for the scar... If it's been a long time already, maybe the doctor was not the best possible.
