I have the same trouble with cup sizes. I was an 8/10 DD/E before I was pregnant and I am finding it hard to get bras in my sizes because althought my cup size has increased, my back size hasn't.

EternalBear, I notice that you're in Newcastle. I have family there and whenever I visit I go to a place called Centre Body Fashions in Warner's Bay because they have a huge range in larger cup sizes and they also have pretty bras. The ladies there also make sure you are getting the right support.

I just bought an Elle MacPherson and I love it!
