Would 300 or 325 cc be the best size for me? (Photo)

I want silicone under the muscle and medium height profil. I feel this 25 cc is not big but they are gonna make the difference for me to be at the good size and happy. I want something natural but not to small not to big . Want to be a C cup but not a D. I am so thin and petite . I am 5"2 and 96 lbs . I feel the 300 cc is good but a little bit small it miss something and the 325 I am scared that is gonna be to heavy and if I want to wear a bra with this volume it is gonna be to big ! I am lost !
