Cosplay season is in full bloom with Mineralblu capturing the best outfits at this year's LVL UP Expo in Las Vegas. Marvel Rivals inspires many, especially the popular Squirrel Girl. Highlights also include Arcane characters, Isaac Clarke, and a rare Chicken Jockey.
"Fans of Fallout have come together annually in Goodsprings to celebrate Fallout: New Vegas Day, creating a vibrant atmosphere for cosplayers since the commencement of the events."
Cosplay originated roughly a hundred years ago but it didn't enter mainstream popular culture until the 1980s. At first it was tied more closely to specific events; by the 1980s it became more widely practiced as an expression of fandom participation.
