What to wear?

Diva has her Christmas photo's on Wednesday and the photographer asked us to bring two outfits. One traditional, one fun. Her Christmas dress is deep red with black velvet shoes, but I don't know what to do for the fun outfit. She has this great pettiskirt that she loves to wear. She's worn it for photo's that my friend took over a year ago and I had her wear it for Father's day photo's that I took. Maybe I should choose something else, but what?
