Wikipedia saved my life like almost a million of times, I always found good information for school projects on it.
But now there's this new site called wikifashion.com, I don't know if you already heared about it.
It is actually just the same as wikipedia, it only doesn't has the information of Albert Einstein or Beethoven.
But on this site you can find everything about fashion.
You can find and catalogue everything about: Blogs, style icons, brands and magazines (like Vogue or ELLE).
So you can put some information of your own on it.
Go and have a look!
