True, rewozz - here is another similar one by Baudelaire:
"Rhetorics and prosody are not arbitrarily invented tyrants, but a collection of rules required by the very organization of the spiritual being; prosody and rhetorics never impeded the distinct manifestation of originality. The contrary is infinitely more true, that they helped originality mature itself."
Apparel arts are not much unlike poetry - dress has rhythm in patterns, metre in cut, rhyme in colours. Originality needn't ignore good form and the latter may be used as a system of reference to channel creativity.
Perhaps taste relies on a deeper understanding of the rules, of their meaning, until they become principles of your own, and represents a creative manner of applying them to an original material. Taste manifests itself in all aspects of life because it is that required "organization of the spiritual being" that applies its criteria to everything it encounters; it is individual, but not whimsical, it has a structure, though hard as it may be to explain it.
Perhaps the best suggestion is in a famous couple of lines of the same master or in a painting of Matisse that interprets them:
"Là, tout n'est qu'ordre et beautè
Luxe, calme et voluptè"
