When I hear about Dandism, the character that comes into my head is Oscar Wilde. A dandy was a man who considered himself elegant and refined, an educated and cultivated person, just as Wilde is described. . A style that mainly affected language and dress. The idea that the decadent movement, before assuming the term decadent in a negative way, would assume it as a flag, already seems to me an act of rebellion and rupture with certain prototypes. I remember Wilde Requiescat's poem:

Walk lightly, she's close,
Under the snow;
She speaks softly, she can hear the daisies grow.

Excellent work, as always, @josemalavem.
