There are so many people out there with a great sense of style and peopel we can trust to help us go the right way in fashion. theses people 9 times out of 10 are famous. I know mine are. Somtimes those fashion icons only help us because they are in the newspapers and magazines. But other Idols are actual people who discover fashion brands (noramly designer) these imspire me because I some day can follow in there footsteps. then there are fashion Gurus people who prech fashion people like Gok. these are problobly are the best ones as they have a bias opinion, they know all bout fashion as well as having passion for the fashion as well.
I think having a fashion Idol is a great thing to have it helps with confidence in your style and if they are famous it doesn't matter if you coppy them a little from time to time. Also you can edit and personalize their fashion and style to make it your own!
