I was a AA until I was 18 and had given up any hope of a bigger chest.....then suddenly BAM!!! I grew to a DD and have never gone back! BUT UNFORTUNATELY....the rest of me grew too!!! I was too skinny previously for my body to "afford" to put any extra up top, then I gained weight for the first time at 18 and VOILA! I have felt grateful to get something positive after so many flat years, but it comes at a cost, bigger hips, thighs etc. and many times I have wished to go back to skinny and flat! Be careful what you wish for and be happy with how you are my friend, it could all change in an instant and it has been pretty much impossible for me to go back. I have carried extra weight pretty constantly for the last decade. Is it worth it? Nah.
