It says in the paper the rear end is a 'solid structure' so I guess it could well be Kev...?
I don't understand how anyone could walk like that unless it's on wheels, how does she move about in it, what if an emergency loo break was needed? What if she got faint under the hot lights and needed to sit down? What if she actually fainted? Would she fall sideways like a horse? What if there was a fire, how could she run? Does it have a quick release mechanism? Too many questions about this costume, none of them answered, it's a health and safety hazard that's all I know
