Fairy exhibitionism
From wipipedia.org
Fairy exhibitionism refers to the practice of dressing up as a fairy and walking around in public.
Someone may be forced to do this as humiliation.
Usually, gauze wings will be worn on the back. Other clothes commonly worn include a tutu (allowing the thong or frilly knickers to be seen), stockings and suspenders or hold-ups, and stilettos. A wand may be carried.
