Best Party Outfits for Princesses

Mermaid and Aura have a very busy evening coming: they were invited to 3 parties, and all of them will take place tonight! The first one is a VIP red carpet party, the second party is a casual picnic with friends and the last one will take place in an outdoor cafe. The BFFs couldn't choose which one's better, but why choose only one party when you could visit all the three?
