Yep, she looks like a normal person on a not-so-great day. It's not the lack of make up--I don't wear make up, and I usually look decent--but the fact that she doesn't have five hundred cosmeticians milling around her at any given second. You know, like SilverC said.
On second glance, she IS wearing make up, and it's part of the reason she looks so awful. It's all smudged under her eyes.
