Fashion is rarely translated into language for me. Some Chanels look ugly or cheap; some people confuse what is fashion with the crowd or status symbols because of their insecurity.
I love the idea of being rebellious, being confident enough in your eye to know and say what looks good and not regardless of the brand tag or what other people say.
Of course people have different tastes, and even for one person taste develops.
Looking good doesn't necessarily mean pretty or attractive...
School doesn't teach taste. School tells students just to be themselves. Being confident, being true to oneself create style and the strength to express it. (P.S. In Mark Snyder's terms, low self-monitors and non-actors are more likely to have taste and not copy others and celebrities.)
No authority, diploma, brand tag, or resume will guarantee that unique eye.
