Mark, it may surprise you to realize the reason plus size women hide their bodies under clothes, is because we live in an extremely size prejudiced society.
I imagine since you may not have ever lived as a plus sized person, you wouldn't be exposed to the endless hatred, stigma, and outright prejudice that is allowed by our society to be said about plus size people.
I understand the show was done in 05' and perhaps you have a better understanding of this now. I just thought, it seemed you were rather naievely shocked at the notion that Kimberly would hide her body under her clothes. Hey, you know plus size women have no choice when it comes to fashion. If it horrifies you so much, tell the fashion world to make something more for plus size women other than tent clothing.
