I have found a reoccurring theme this year in wedding cakes. Tone on tone (whites/champagnes/ivories) or complete contrast. Here is a nice example of a cake done in all ivory. So elegant and simple, I adore it. And she's tall enough, grand even, that she doesn't need more. This one is a set of 6"/8"/10"/12" round cakes, the 8" layer is doubled in height.
