I don't know why some people need to be so rude on here as stated up thread. It was put on Pinterest for the world to see and had called it retro. I don't think it's retro so was just looking to see how others would describe the style.
I can see where they're coming from with 'retro'. My immediate thought on the photo was 'feature wall' - one wall papered in a pattern and all others painted a plain colour. And 'feature wall' to me screams 1980s.
TBH it's really not got any discernible style at all. Not saying it's horrible, just that it looks like the normal mish-mash of stuff that you acquire over time, rather than stuff that's been put together deliberately for an effect.
