Actually talk to the characters! They really then interact with you. Tell the sisters that they are beautiful and that the step mother is a great mom, afterall, the chores did have to be done first. basically anything that makes them "look good" vs how they were "portayed" in the movie/story. Oh, and if you think DD may be a litlle "put off" or scared of thier costumes show her some pics first (I have some if you need them)...DD3 and DS5 didn' know what to think of them at first, but ended up loving them (and Cindy and the prince) and the meal.
