Every little girl loves to dress up as a princess! This Halloween your child has lots of choices, beginning with perennial favorites Cinderella and Ariel from the Little Mermaid, and for the more adventurous, an asian princess in a kimono, a la Mulan!
There are many princesses to choose from, of course. Disney has a whole page of princesses in one place. Other choices include Cinderella, Ariel in The Little Mermaid (the Hans Christian Anderson story is not as happy), Mulan (who is based on a chinese legend), and Sleeping Beauty.
