This one was interesting in a couple of ways and took some forward planning to work it in. First, it is run alongside other experiments. Essentially, one participant undresses in front of the rest of the group but then he or she must remain naked during the next few experiments. The idea behind it was to measure how rapidly someone who was shy about being naked would get used to being exposed. This ended with the naked one standing on a chair (still naked!) while letting the other participants get a close up look at her, something that she would not have been able to do at the start of the experiment session.
