This made me chuckle because you can, of course, interpret this in many ways. If you are a boy you could see this as a directive and perhaps even a legitimate reason for not washing. This however, is more about not washing your jeans and is part of a window installation in Selfridges. You just have to love their perspective. Personally the thought of not washing (and still wearing) jeans for six months does very little to inspire me, but maybe that’s just me!
