I love this chick - her voice rocks and has since since early American Idol days. What I don't love is her stylist. Who the hell thought putting her in that dress would do her any favours? She needed an A-line skirt which didn't hug her overly generous thighs. The pulling of the fabric across her thighs didn't add anything to her body either.
This is what her stylist should have chosen:

A lower rounded neckline would flatter Kelly's face and the dress would balance her shoulders and her hips, the boots combined with matching tights would add height to her figure and take away some of the stubbiness. Not to mention she is dressing like she's 50+ in the video. Gawd.
Now onto the hair. Her face is too full/bloated looking for a pulled back ponytail. She's quite cute and hair around her face would soften her quite a bit. Here's how she HAS looked with better hair.

See all better now.
Hey Kelly I won't charge as much as those stylist's you've got on your payroll - call me k?
