I too have boy/girl twins who just turned three, I was thinking about Mickey and Minnie Mouse, they were ghosts last halloween, but are now into Dora and Diego (not sure how easy this one would be). I also think that a prince and princess would be cute. My son is not very big on hats so I think I'll have to find something with face paint that will make them match, maybe this year I'll make them both clowns.
Way to think ahead I should be doing the same thing.
