I really like Kelly Clarkson. She is a really good person. She can really sing and she made two really good albums.
Her winning moment on AI was rated by TV Guide as the 11th greatest moment in TV history. In that moment, she looked cute in jeans and a red velvet jacket. Unfortunately, that was the last time she would look cute in anything.
Others have alluded to it here, without coming and saying it, but Kelly is a horrible dresser. In fact, other than a video, where she probably didn't dress herself, I have never seen her in anything flattering since the Idol moment.
