Hologram clothes

A hologram projector projected hologram clothes on people's visual cortex, allowing them to see others who were naked as if they were wearing clothes. The Eleventh Doctor and Clara Oswald used hologram clothes while at the Church, abiding by their nudity requirement, while appearing clothed to each other. (TV: The Time of the Doctor)
