What can I do to correct my uneven breast & downward facing nipples? (photos)

My breasts are different sizes. I know it's normal but it's very noticeable to me & I don't like it. They differ in that one is basically one inch larger in diameter (is that the appropriate term here?). I like the size of the larger breast which seems to be a full B or small C. The larger breast fills the cups in my bra but the other does not. In addition to that my nipples face south. I haven't had children but when I do I want to breast feed. That is very important to me.
