I am a 34 AA, slim, 42-year-old who is very sporty. My ribcage under my breast is 30 inches. I am having breast implants and don't want to have large breasts, just some! Under the muscle my surgeon says, but sizing, he recommends 200 cc. I am thinking maybe 175 cc or is that pathetic? Also, I have been told you can lose 10% by going under the muscle? What would you advise for me?
