I love soft pink peonies, they are probably one of the prettiest flowers there is. I'm also a big fan of the ombre effect on a cake, used here so so well. I'd wear a dress like this cake, with the peony in my hair.
Kate and Wills had a seriously fantastic decorator for their epic royal wedding cake. It's fruitcake which I don't really understand, as fruitcake is just not tasty. But it is incredibly gorgeous and gigantic: 8 tiers of different flavored fruitcakes, each with a different decorating scheme. I'm mad impressed.
