I had my first breast augmentation in 2004, with saline I am now switching to silicone to have a more natural feel and appearance. I am 5'4, 100lbs, 32 medium C, 25,33. My implants currently are 390 filled to 425 moderate profile. Here is my question. I know there is a slight difference between saline and silicone. I want to go up about half a cup size (32 medium C to small-medium D) if I have a 425 now what should I raise it to and should I stay with my Moderate Profile or go to High Profile? I will appreciate any responses as I am still quite nervous. Thank you so much for your time!!
