I was told by my p/s that I do not need a lift. I have no photos. I am 58 years old, 5 foot 5 and weight 115 pounds and I am in very good shape. I would like more volume at the top, as if I am wearing a push up bra. My thoughts are that the 600cc may be too large and 550cc would still appear bigger than what i have now, I would be satisfied going up one cup size. I do not want to end up looking shorter and heavier. Would the 550cc silicone h/p, look larger than what I have now?
