Where did you read that she wore a "body suit?" Can you give us your source for that?
Reports I read said she was wearing a see-through negligee when the Kroger guard, police and hospital personnel saw her.
The discussions about the photographs of the dancers arriving and leaving have described what she was wearing and that the clothing (more like a costume) was intact when she left. She is described as wearing a skin-colored body suit with a red lingerie top and bottoms (I'm guessing those short, silky nylon little dance or jogging shorts). It's been discussed numerous times, and was originally described by one the defense lawyers telling about what all the photos showed.
Yet she was found in a nightgown. How did that come about?
