I just wanted to ask a question regarding the average time it takes for breasts to fully develop. I know each person is different, so if someone, perhaps some girls who have fully developed already, please answer this and let me know.
Breast development and how long
Everyone is different. Nobody really knows how long it will take a particular person to develop. Some women fully develop in one or two years, while others it's several. I was a B Cup until about 7th grade, and then I went up to a C Cup. During my college years my breast size increased and I'm now a D Cup.
