Can anyone help me decorate?

I am going to be an RA this coming school year and I need help decorating my floor! I want to go with a vintage/sophisticated theme but I can't think of where to go from there. I mainly need some awesome door decs and one or two things to make for the walls to make our floor look nice but I just need someplace to jump off from first! Any ideas or sites you can give me would be much appreciated. Thanks!
