I would love to shrink to a B Katie.
Scarlet, unlike most people losing weight, I don't have strict guidelines or rules. This works for me since I do not have trouble with portion control or some of the other problems commonly faced by those who are losing weight. I was also never really overweight. The point is that my method works for me but probably won't work for everyone, especially if one needs to lose a substantial amount of weight or needs to learn what a reasonable portion size/calorie intake is. It's not intuitive for everyone.
In short, I eat everything I want, but simply eat less of it. Small changes in my diet were sufficient for a 10-15 pound weight loss. I am vegetarian so my diet is already full of veggies and legumes, and I keep my feet moving whenever possible. I hate exercise for the sake of exercise and I know I will never maintain any kind of workout, so I just try to integrate as much movement as possible in my everyday activities (might be a bit trickier in suburbia but it works for me).
Back to bosoms--I don't think the 5 pounds I have left are going to result in 2 cup sizes lost, but I guess we will see. I just don't like how sensitive my tissue is to even small changes in weight. At 120 pounds I could still theoretically be a healthy weight and very much a normal size (probably a 6) but my chest would probably be creeping into GG or H territory. I'm tiny now but things change and I would like the peace of mind knowing that even if my metabolism changes, I won't have to worry about my chest exploding.
