2 Questions ladies.
1. Roughly what age do your boobs stop growing
2. do you wear different size of bras depending on make/shop ect?
my gf wears a 32a bra and she has since i have been with her , i decided to buy her some underwear to suprise her , when she tried it on it didnt fit and she needed a 34b . yet all her 32a bras fit.
It depends on a lot of things (genes, pregnancy,age etc, etc). Some people stay roughly the same size or even get smaller, some go up and down, others just get bigger as time goes on!!
Also sizing not only depends on make but style of bra. Its possible to need different sizes buying even if the same label as usual, but a different style. So its perfectly possible that your g/f's breasts have not actually got bigger, but her change is bra size is purely due to the vagaries of manufacture. Yes, its bonkers and confusing. welcome to the world of boobs and bra-wearing!!!
