WARNING: I'm about to post a link with many pictures of Sarah Palin. This is for fashion/style reasons, not to talk about politics. Unfortunately, she's the only example of this that I found.
I just came across a website where they photoshopped out Sarah Palin's hairstyle, makeup, glasses and accessories. You can move the mouse over each image to see the original. The change is astounding. It just goes to show how some small changes make a HUGE impact.
