Cosplay at Seattle Worldcon

Three fabulous persons dressed in retro sci-fi fashions, one with green hair wearing a green mini dress, one wearing a purple and pink jacket and trousers, and one with pink hair in a yellow lab-coat inspired look, who seems to be exiting through a door in the vibrant teal wall.Cosplay is encouraged at Seattle Worldcon. So plan ahead and pack accordingly! Special costume-themed events will occur each day.

Wednesday: The Prop Contest
