In Anaheim, California, thousands of cosplayers went to WonderCon in costumes and make-up and with props.
People of all ages come to the event every year to see every type of fandom, such as games, comics, TV shows, movies, books, and costumes!
Difficult words: cosplay (when people dress up in costumes as their favourite fictional characters), WonderCon (a convention where people celebrate fictional things or things that make you feel ‘wonder’), prop (a thing used in a film), fandom (being in a group of other fans of something).
