Anna challenged her sister Elsa and their friend Moana to a pick the best outfit of the day game. This means that you will get to take a peak in all of their wardrobe and play dress-up with them. Choose a nice college outfit for Elsa but don't forget that Moana also needs you to choose a fab outfit as she want's to win the challenge. And I think Anna may be more interested in winning this challenge than she admits - so definitely don't forget to pick something nice for her!
