Fan costuming caught on, however, and the 2nd Worldcon (1940) had both an unofficial masquerade held in Douglas' room and an official masquerade as part of the programme. David Kyle won the masquerade wearing a Ming the Merciless costume created by Leslie Perri, while Robert A. W. Lowndes received second place with a Bar Senestro costume (from the novel "The Blind Spot" by Austin Hall and Homer Eon Flint). Other costumed attendees included guest of honor E. E. Smith as Northwest Smith (from C. L. Moore's series of short stories) and both Ackerman and Douglas wearing their futuristicostumes again. Masquerades and costume balls continued to be part of World Science Fiction Convention tradition thereafter. Early Worldcon masquerade balls featured a band, dancing, food and drinks. Contestants either walked across a stage or a cleared area of the dance floor.
