Sounds pretty fun.
When I was at University of Texas, I dated a girl that was really into Cosplay, especially Marvel and DC characters. She would dress up like Wonder Woman, Black Widow, Harley Quinn, ect......even if we were just going out for a movie or to a restaurant, every single time we went out she was dressed up, LOL. I have to give her credit though, she put in hours and hours and hours on her costumes as well as a good deal of money, from sewing the fabric and cloths for the costumes to face and body paints, to accessories like a piece of rope she had dyed gold to look like Wonder Woman's lasso. That's dedication, I am sure some of the people you see at the furry conventions do the same with their costumes.
