I've measured myself 15 different ways at least and tried on a bunch of stuff. My measurements say I am a 36AAA. My ribcage is more football-player shaped than girly, and I am obviously pretty flat-chested. I can make do with a 36A, but it's still way too big in the cup area. I can't size down to a 34A because it won't fasten.

I know there have been lots of suggestions on where to find bras for the well-endowed. What about for those of us who are not endowed at all.
