Which Princess do you think is most popular with every age group?

I agree with Cinderella but a lot of little children really love Aurora, like my six year old cousin. I think elderly people love all the classics; especially Snow, who my nanny raves about!

Cinderella.
Because kids already familiar with her story (especially little girls), and teenagers and young adults wants to like her (married the Prince Charming).

I'd say Belle, I think she is able to appeal to any age.

Belle because she appeals to more 13 year olds than younger kids

For my age group, I would say Elsa. My friends and I love her!! :)
