I read the #MeFi thread in 2012. Lingerie people confirmed I was 32A. 2016, talked to someone who knew her stuff: 30C. Last month, I noticed the past year of emotional potato-chip eating (thanks, 45) meant I needed a new size. New bras fit great: 30D
I'm still what jerks call "flat chested." Just realizing now: my (old, wrong) idea of "D cup" is from jerk hetero male colonization of my mind.
