How did you get into cosplay, and how long have you been doing it? But one admitted: ‘I will be purchasing 10 gallons’, while another added: ‘The fact people actually buy this stuff is hilarious, girl you have to much power’. I think it’s been about five years since I first dressed up for a con. The genre’s origins are as old as the medium itself, though action films as we know them didn’t really take off until the 1970s. With the development of computer-generated imaging, or CGI, and other technologies, they’ve continued to prosper well into the 21st century.
