The first people to wear costumes to attend a convention were science fiction fans Forrest J Ackerman and Myrtle R. Douglas, known in fandom as Morojo. They attended the 1939 1st World Science Fiction Convention (Nycon or 1st Worldcon) in the Caravan Hall, New York, USA dressed in "futuristicostumes", including green cape and breeches, based on the pulp magazine artwork of Frank R. Paul and the 1936 film "Things to Come", designed and created by Douglas. Ackerman later stated that he thought everyone was supposed to wear a costume at a science fiction convention, although only he and Douglas did.
