besides the over-exposure of celebrity "style", a lot of this must have to do with the fact that fashion is now so easily accessible due to the internet. you no longer have to be invited to a fashion show to have seen all the looks from it right away...you can find photos of the entire thing the night it happened, within less than an hour sometimes. so any old person from a farm in middle america or a random tiny eastern euopean town can know exactly who john galliano is and what his last collection for dior was like and even about less-than-mainstream designers if they have internet access. it makes fashion much less exclusive than it ever was before because anyone can see it, heck you can even buy it if you have the money thanks to websites like net-a-porter.
