Breakfast at Tiffany's room?

I am moving into my sorority house this year and want to make my room Breakfast at Tiffany's themed room. In the room there are 3 desks, 3 closets, and a day bed. I am trying to figure out some ideas to make my room look extremely different and need ideas. I was also wondering if anybody knew of something that could adhere to the walls like paint but wont damage them
