I had 400cc when I had my first BA from an A/B cup and I am a D/DD I’ve had them in for 10 years now and overtime they almost seem like they shrink (most probably gravity) as do not look half as big as I did and do not fill my bras the same. When people say they are a certain cup size, remember that everyone’s opinion of filling a bra is different and that each shop’s bras size up differently too xx
