I'd say Snow White or Aurora. First I eliminated the girls who weren't princesses by birth. That left Ariel, Jasmine, Aurora, Snow White.

Ariel doesn't act very princessy, and isn't a princess in your traditional sense.

Jasmine isn't the main character of her film. But i'd consider her.

Aurora spent half her life as a peasent...although the same can be said for Snow White, but at least she knew she was a princess.

When I think "Princess", I think of Cinderella...she has the most known fairy tale IMO. She has a hard life, and finally her dreams come true in the end. She is sweet, caring, and NEVER gives up hope. To me, that is ultimate Princess material :D

Cinderella is easily the most famous but I also chose her because she is the one that is most popular with young girls.

I also considered Aurora because the stereotypical princess most people think of has blonde hair, a pink dress, and a tiara.
