hi there!! i think you have prob seen my pics, everyone has, but yes you wil achive a dd cup with a 340cc!! i was a very flat empty 34b after 2 kids, and a 340cc has given me a 32e!! i wasnt allowed anything bigger either, a 340cc is bigger than you think! i can actually feel the implant under my skin! and its quite big! but mine look very natural! you wil def not end up with a c cup! i can tell you now! you,ll prob end up measuring a 32e like me! you must remeber though, when you have them done at first, they will look flattish,but after a few weeks and months you will begin to notice them stick out more and soften, and will be pleantly suprised how bigger like they.
my friend was a 32a and had 340cc under muscle and she is a 32d! so your def def guna get a dd! XX if you havent seen my pics let me know and ill email you my album or chk out sofem i am janey22 and password is boobies oh and i am a size 10-12
