1. One who poses to know all there is to know about fashion; 2. a self-proclaimed fashionista with no real sense of personal style; 3. A serial style copycat who wouldn't be able to get dressed without the latest issue of InStyle or Us Weekly.
Use faux for short.

All the fauxs are anxiously waiting to mimmick Carrie's outfits from the Sex & the City movie.
Anything related to fashion that inspires(a person, piece of art or outfit to name a few).
Fashion + inspiring = fashion-spiring.

She stepped onto the red carpet in a fashion-spiring gown stealing the spotlight with camera flashes abound.
