well if you only wanna be a c to a small d id recommened a 280cc, or maybe 300cc!! but u must remember, implants always measure alot bigger. for example i was a 32b like you and i had 340cc overs taking me to a 32e/f but they only look a d-dd in clothes and not that big at all!! so if i was you id go for the 340cc if you are offered it. you dont wanna pay all that money and not even notice you have had them done,so 300 to 340 id say. hope this help XX
