27 y/o mother of one with zero to none boobies - Los Angeles, CA

So i have a daughter and I really don't plan on having anymore kids but if I do, it won't be for another 4 years. Anyways, I went in for my first consult with Dr. J in Pasadena. He is a physician through Beverly Hills Physicians. I read no bad reviews on him so that's why I decided to give him a try. My consult went pretty good. He recommended I have a crescent lift on my left breast because it's slightly lower than my other breast. I want silicone so he will be inserting them under the muscle and through the nipple since he is already going to be in the nipple area doing the lift. I told him I wanted a full C and he is going to give me that but said he recommended a small D so I don't have that "I should've gone bigger" playing in my head after.

Now because my breast sit far apart he said he would insert them in a pocket so that I could have cleavage. But I read somewhere that I could possibly look like I have a uni-boob. So should I say no to the placement so they sit closer together???

Also I do have one breast that is bigger than the other. I don't know about this whole 250cc's 350cc stuff. So we never even touched base about that. He explained everything else. But I want to go back for another consult to talk about that stuff. Any insight?
