Hi, everyone. I am schedule for my BA on 12/21 (Merry Xmas!) and have decided on under the muscle, saline. The only thing I am still obsessing over (like everyone, it seems). I am currently a B cup, 145lbs and 5'5. I would like to be a full C cup. I want it to look as natural as possible. At the PS I tried on a 265cc and 310cc but couldn't decide between the two. I am wondering what the difference between these two are. How profound is the difference? I have a difficult time understanding the numbers and would really appreciate any help.
