Popular culture and porn go great together, and cosplay is good evidence in support of that statement. People love fucking in costumes, taping themselves fucking in costumes, and watching other people fucking in costumes. That's why VR Porn Videos has such a large collection of cosplay videos. People are making Christmas specials, dressing up as Santa Clause and Elves, take roles of Super-Heroes, or other comic book characters, reenact board and video games... Fucking in costumes is just fun. Masquerade balls have been a chance for a bit of promiscuity for ages, and it hasn't changed. The sense of adventure keeps things great.
