I wore sports bras to hide my boobs until I went fulltime and then starting wearing regular bras at a 34A. I do not like push-ups and have never worn them. Now, after some weight gain, adding progesterone, and time (mostly time) I'm a 34D. I have wear a bra or else I jiggle and not in a comfortable way. I also noticed that my boobs look better supported now that they grown.
