Dirty hair and fingernails

I'm really confused by this new "fashion" I've been seeing a lot of lately, specifically on women, of not wearing makeup and looking like one has not bathed for 8 days. It's really unattractive and makes the world not want to touch nor be near the entire group of people engaging in this wretched subculture. What's wrong with bathing and not wearing unflattering vergeonhooker clothing? It is very dirty.
