thats a great photoshopped image of an after pic!
As far as cc's go she may could handle that much but if this would be her first augmentation Im not sure that it would be possible for to get that large especially if it is under the muscle. It all depends on how much the muscle will stretch. I have been twice my first time I had 480cc saline and now I am 750cc silicone. I would definitely recommend going as big as possible though....because chances are with her build and if she goes under the muscle it will take quite a few cc's to make a big difference, but then again I am not sure what look she is going for.
