Hello.
You are underweight according to your height.
U should concentrate on increasing your body wt generally.
Do little exercise, eat healthy, take good rest .
Breasts are mainly fatty tissue, so if u are overall very thin then probably even your breast size would be small.
You should put on wt and everything else will improve eventually
