How to do 50s-style curls with naturally curly hair?

So my hair is naturally pretty curly and I have no idea how to style it, period. This Halloween, I’m going to dress like Sandy from the very end of Grease, and I was wondering if there was a different way for me to style my hair than, say, a non-curly girl. Or just any tips in general.

If you need a reference, my hair looks a little like this: http://d277vln4jzkhhg.cloudfront.net/wp-content/uploads/AnnaLynne-McCord-controlled-waves.jpg

And a quick reminder of Sandy’s hair: http://farm3.static.flickr.com/2742/4467018473_735aab8593.jpg

And if anyone has ideas for a more modern (but still true to the film) version, that works too! :) Thanks in advance to everyone.
