I had smaller breasts all through my 20's and decided when I turned 30 that I wanted to go a little bigger. I was not getting implants for attention, I just wanted to feel more womanly in bathing suits and lingerie. I just wanted to be able to actually fit into things I wanted without padding or push-ups. I only went up to a full C cup (small D) which looks more natural with my figure.
The healing after surgery was painful, but completely worth it and I feel more confident and satisfied with my body then ever.
