I found this really great article/post on Wikihow, on how to look like a star for a minimum of cash. 

It explaines in a few steps, how you can budget your purchases and how you can update your wardrobe with " what-to-do's" and "What-not-to-do's". 

For those who want to look like a celebrity but don't necesarily have the cash of a superstar - read this.
