IT's literally like when a girl first starts puberty and seems to get breast overnight after being flat chested 8 hours ago.
I never had bras that truly fit.
A study of women with an average combined breast weight of 9.
Anyway, long story short, if anyone is wondering about it I'd summarise as: "Macromastia occurs as a result of progressive growth over time, resulting in breast size that far exceeds normal limits". As of late, I've had an on-going growth--someone last time tried to say it wasn't possible, but i can't measure my breasts, the inch tape is too small.
