Implant revision size recommendations - will 400-450cc be too much? (Photo)

With your small size and frame, I would not suggest going that large. This will just stretch your own tissue even more and sag with time. Plus, these implants will feel heavy on your neck and shoulders.

I suggest consulting with plastic surgeons appropriate implant exchange.
There’s a bit more involved in the decision, making then looking at pictures and recommending size.
Find the right provider, and they should be able to guide you through the process in a simple, straightforward manner.
