I recently bought a nice wool scarf for very cheap. It was long and black and quite good. Then I decided to wash it - because it came from a second-hand store, and is wrapped around the mouth and nose. Apparently, some materials are supposed to be allowed to accumulate dirt and nastiness ad infinitum, because they are very difficult to wash. Like, for example, wool. The directions said "wash in warm or cool water, dry at low heat". This I more-or-less did, but the stupid thing shrank precipitously and became much lighter in colour. It's still nice and warm, and I know it's clean, but the shape change pisses me off.
Why has this problem not been completely, utterly solved? I know women's clothing is ridiculous, so I don't really expect any solutions there - you buy clothes you can't wash, why, exactly? But I digress; why does men's clothing exist that cannot tolerate being clean?
The technology exists to cheaply manufacture high-quality clothing that will not suffer from treatment recieved in a standard household washing machine or dryer. The overwhelming majority of the clothes I own are made of such cloth; some are labelled "preshrunk". The few items that do not have this trait that I own are irritating.
Please don't tell me that I should have been more careful. First, you must justify why any clothing is sold today that requires extraordinary care - then you can tell me why I need to exercise such care.
