Disney Princesses

As is well known, Disney has come out with many movies, many of which have/are centered around a princess. Looking back at when these various movies were made, I can see a pattern of behaviors and appearance among these princesses. Starting with the older movies, Cinderella and Snow White, it is easy to see that these women are dependent and natural house workers, just like women were stereotypically during the time period from which these movies were made. Also, back during a time when woman didn't wear such revealing clothing, Cinderella and Snow White wore full blown gowns, showing no skin on their bodies other than their arms and occasionally their legs. Going into the future a bit to The Little Mermaid and Beauty and the Beast, clothing for these princesses are still gowns and dresses and such, but they are more interested in learning and being independent of how other girls acted, much like how girls were making a stand for themselves in the real world. Closer to present day, with Aladdin and Tarzan, the "princesses" wore much more revealing clothing. Where as Jasmine wore a very revealing top and baggy pants, Jane, by the end of the movie, was wearing a fur/cloth bikini. They were also just as, if not more, independent as the previous princesses.
One thing that has not changed throughout the years though, is the whole chivalry thing, with a male character being the hero of the whole film. The Prince woke up Snow White, The Prince saved Cinderella from her evil step-mother, Prince Eric saved Ariel from Ursula, Beast protected Bell from wolves and violent men, Aladdin saved Jasmine from Jafar, and Tarzan saved Jane from baboons and a mad man of a hunter.
Disney tries to change their movies by incorporating current time attitudes, behaviors, and fashions, but they also stick with the classic male saves girl story. It doesn't really bother me too much, on the account that girls are becoming more independent in the movies, but I'd still like to see a movie where a girl saves the day with out it being a blockbuster disaster (I'm looking at you Ultra Violet and Catwoman).
