the subsaturation fallacy

I was in need of cheering-up at lunchtime, so I popped to look at pairs of full-length trousers in shops, feeling that this frequently fruitless and misanthropy-inducing activity would be ideal for reducing my despair levels. Most surprisingly, after only one shop filled with 'slim leg' things or modern urban clown trousers with knee-level gussets I found something potentially wearable, albeit only if they stretch back into the position of function after each was, as do my current favoured leg-concealing employment-breeks.
