I watched the show and I didn't think Carolyn was offended. It looked as if she was going along with the joke, no matter how lame. I feel that anyone who goes on that show knows they are fair game. I have never cared for Carolyn, but she looked cuter in her casual clothes than she does in those suits. I personally thought the shoes were way too fancy for such a casual outfit, but that's just me. Everyone else may have liked the look.
Now let me ask you, did Star Jones not look like a beached whale in that exercise suit? She has come a long way since she wouldn't do anything you couldn't do in full dress. She has lost weight, but not enough to wear that outfit.
