When selecting a party theme, give some thought to the kinds of things that your child likes to do and the age group that is invited.
Chances are, other kids are just as enchanted by the same stuff.
Royal Party Kids can arrive as noble knights and princesses. Invitations could be a royal proclamation from the King or Queen. Decorate the party room like a castle and offer shields and scepters to the guests. Action Figure Guests could dress as their favorite action figures. Cultural Kids can dress up in their favorite traditional cultural clothing.
