Will 200 Cc's Make a Difference in Cup Size?

Hi there,
I think that given your relatively small frame, the volume increase you describe would produce a noticeable size increase.
The main point to emphasize, however, is that you should do your homework on the long-term effects of such a large implant too. Very large implants are of course heavier implants, and over time will cause a significant change in your skin and soft tissues which may lead to premature sagging of your breasts (possibly leading you to feel like all of the money you've invested in their appearance was for a short term benefit) and the need for more frequent surgery than might have been the case with smaller implants (for example, if you decide you need a breast lift to deal with all of the new, stretchy skin).
Be careful that what you think you want now doesn't cause you a problem you'll be dealing with for many years in the future. The elasticity of soft tissues, once lost, cannot be regained. We can sometimes camouflage lost elasticity by removing skin, but the quality of the skin is never the same once it has been stretched to this degree.

Yes, 200 cc's will make a difference, but I think they will be too big for your frame.  You are a small woman and even the 650's  are probably too big.  Remember, the larger you go, the more unnatural they will look and feel, and may result in earlier sagging.
