What to wear to a photoshoot?

A flowy top or dress would be cute... maybe a white one, and with some type of girly cowboy boots/cowboy-looking heels (if you know what I'm saying) with wavy hair (especially if your hair is longer in length), and natural, but maybe a smoky natural so you can tell. Any makeup really, except anything too dramatic/black. You don't want to go overboard! :)
