breast development

when y’all were going through puberty and everything.. did your boobs grow in certain areas before others? like i have little to no growth on the bottom of my breasts yet the outer parts are getting to big for my bras. i cant wear t-shirt bras because theres always gaping in the cup. i can only wear push ups but even then they overflow out of the cups. :/ i need some advice from women. im 14 1/2 years young.

i have also read that having a fast metabolism can cause small breasts because they are composed of fat. i have a fast metabolism, does this mean i will always have small breasts and a small butt?

i have wider hips but a small butt and chest. :/
