Everybody's all up in arms about this "women are all wearing the wrong bra size" (GASP!!!!) so let me just say that *technically* I wear a 30-B, US sizes. But anyone who has ever shopped for bras can tell you, this size does not exist in stores so I wear a 32-A (which is a larger band with the same cup volume). I am loosing weight so I expect that my band size will change but just to avoid being too complicated, I basically want to be a 32-C. Though I'm sure it will really be like a 28-DD or something silly like that!

I understand your pain. I wear a 28F. However, the size does exist! Funny you mention wanting a 28DD cuz that's the size I started at. Anywho, here are some links:

Herroom: You'll have to do the search for 30B yourself. I couldn't get the premade search link to take.

Good Luck! and don't suffer with ill fitting bras! Before I found my size was actually made I gave up on bras and wore overbust corsets because I couldn't stand having to constantly pull my band down and my straps up. I have purchased from both Herroom and Figleaves. I know other friends who have purchased from TLBC. Also, don't forget to check ebay.
