I'm a 32E/30F (depending on the bra) and I find it very hard to get bras to fit. Most large cup sizes seem to automatically come with a massive band, like they assume if you have a large chest you're a whale. for an E/F cup I usually find they start at a 34/36 band, and most smaller bands seem to stop at a D cup. I think fatties are starting to skew the curve in the wrong direction.
