Definitely Duran Duran posters!!! Also lots of pages out of various magazines with other teen stars.
My parents didn't want to splurge for the clear phone. We took a different 80s inspired approach to my teen room. My parents let me pick a different paint color for each wall. It was an oddly shaped room, so I had six walls. I know one wall was 80s style color splatter. That was the first wall we painted since it was the messiest...but definitely the most fun to paint. They also got me a blank canvas, so one of the solid colored walls could have a splatter painting to match the splatter wall. I believe the other walls were hot pink, light pink, black, bright yellow, and blue. My phone, which was solid red, was something they also allowed me to splatter paint to match the room.
My mom sews, so she went out and got fabric in the colors of my walls and made a duvet to go over my comforter, a pillow sham to go over my main pillow, and created accent throw pillows to go with the colors. It was a color block pattern of her design. My sheets were blue to match the blue wall.
They replaced my overhead light with 80s style track lighting.
