Dandyism is not, as many unthinking people seem to suppose, an immoderate interest in personal appearance and material elegance. For the true dandy these things are only a symbol of the aristocratic superiority of his personality. What, then, is this ruling passion that has turned into a creed and created its own skilled tyrants? What is this unwritten constitution that has created so haughty a caste? It is, above all, a burning need to acquire originality, within the apparent bounds of convention. It is a sort of cult of oneself, which can dispense with what are commonly called illusions. It is the delight of causing astonishment, and the proud satisfaction of never oneself being astonished...
Charles Baudelaire,
The Dandy
