Interesting fashion choice on her part. Looks like she was wearing jeans and either a blue dress over that, or else an oversize blouse or smock.
Maybe she is obsessive about modest attire. A dress obscures the view of the contours of her butt and crotch areas, and jeans rule out upskirt peeks. If so, she must be experiencing intense humiliation being put on display like this.
Wonder if there is more than one guy in the room? I am sure she will soon be blushing at both ends!
