I currently have 330cc moderate profile and im really upset about the size so im getting them redone. I want a good difference in size and dont wont be be let down after another surgery. Im currently a full C cup and want to be a DD the surgeon recommend 390 and 420. What one would give me a better result? I want to look heaps bigger maybe a full cup size bigger but not over the top. Im a size 6-8 and slim build
