How do I figure that out? Never been big enough for cute bras (38-40 A), so never really needed to know. But after seeing the results here, I really want to try this out. It's so hard to look girly when you're tall and flat chested.
I'm assuming you're talking about size of domes and not size of bra here.
I'd suggest emailing Lucy: lucy@noogleberry.com and maybe giving her your measurements and the like so she can help fit you.
