All those ancient meanings are useful to draw a line of concepts and trace back what's fashion and how it works. Philosophers use etymology to give interpretations.
But the phenomenon comes before the word which defines it. Not today, maybe, but sure at that time.
Working fabric was such a crappy job that the first strike in western history had indeed been held by the Ciompi in Florence (whose job recalls the tortures of Dante's Inferno). At that time and worldwide, fabric was the big deal, as google stock-option nowadays; wearing the most sophisticated output of such an industry was a sign of distinction. But that distinction between poor and rich was not enough.
It was the time of the Italian Renaissance, the victory of a new cultural model that enhances individuality. When Savonarola tried to stop the tendency, poor and rich people together burn him alive at Piazza Signoria, where still today there is, as a memorial, just a circle on the ground.
We still hate him now.
And that's why the concept of "fashion" is double-faced: on the one hand it uniforms, it has to make everyone feel confortable in his/her own social group; on the other it distinguishes, it has to make each one stand out. That's also why no one really understands fashion, people get burned and we allow farmers to decide what we wear.
