How can I style my hair like this?

I love this hairstyle: http://www.thenewhairstyles.com/wp-content/plugins/wp-o-matic/cache/5ae2a_rihanna-red-hair-styles-1.jpg and I was wondering if anyone knew how I could get my hair up like that. I'm graduating in a month and a half and this hairstyle would go perfect with my dress! Any tips would be appreciated (even a YouTube video)
