Uhm, hi. I have a similar problem -- even things that think they're A-cup are often a little roomy. If you don't mind my asking, where have you found bras that actually provide some semblance of support?
(Obviously this is less of an annoying problem than for large-chested folks -- lack of support doesn't give me back pain or anything, it's just annoying. And I'm sick of having to shop for bras in the preteen sections.)
