Scarlet's thread on foundation made me realize that I don't really "get" foundation. I am not sure what to be looking for or expecting. So how do you even start ? Do you set an expectation of no pores, no age spots and then go from there ? Do you go to a make up counter ? I feel that I want to explore this, but I am not even sure what I am looking for in a foundation and what it should do for my skin. ( I am not even sure what "light" coverage means..maybe I should just take a class. )

Thanks in advance ladies for any clarification on this.
