Music

While music has never been a fandom that Irvin takes to as enthusiastically as books, theatre, and film/TV, he would occasionally run into events that called for a costume from the world of music.  By and large, this comes in the form of themed dance parties celebrating a particular genre or artist, and Irvin makes sure to dress for the occasion.  And of course, with the exception of an undead fictional character, all of the musicians Irvin cosplays are women.  As if anyone listens to music made by men!
