She might want to try to go up to F cup. I'm not sure if she owns any of the other Panache bras, but if she doesn't, please let her know that European brands tend to fit a bit shallower in the cups vs. American brands. So American E or DDD, is compatible to Panache F or maybe even FF, depending on the style, cut and the fabrication of the bra. So the best best, is to try the F cup and see how that works.
