That is because it looks like a wallpaper that a whole episode of The Good Life could revolve around. Margo would buy it because she saw it in a documentary about Princess Margaret but it would, through a series of hilarious mishaps, end up lining the floor of Tom and Barbara’s chicken house. You can’t wear a plot device.
Interestingly, the company that made it, Rael Brook, is still a going concern which implies it was fashionable at some point. I can’t see me wearing it again though. Free to a good home.
