Yeah, I carried on wearing my old underwire bras until only a couple of weeks ago and I really regret not wearing a proper support bra, near the end my boobs hurt so bad, and were bright red and sore from being so uncomfortable.
(Still convinced I have the smallest boobies in the world)
I am just now filling out a B cup and have clevage.....
Now, I have to stop wearing my underwire bras and buy a granny bra?
