Of course those that scoff at the vanity of others, have never done anything vain themselves, to improve their appearance to others.
Like shaved.
Washed.
Brushed the dandruff off a jacket.
Combed their hair, or used a product such as Brylcreem, or oil.
Even polished their shoes.
In the strictest sense, all totally unnecessary.
Except to pander to vanity.
