BOHEMIAN

The Oxford English Dictionary's definition mentions someone "especially an artist, literary man, or actor, who leads a free, vagabond, or irregular life, not being particular as to the society he frequents, and despising conventionalities generally".

Bohemians were typically urban, liberal in outlook, but with few visible political passions and, above all, creative.

Or, as Oscar Wilde put it: “One should either be a work of art, or wear a work of art.”
