I only have a few pictures on hand of me in Halloween costumes. I'm sure my mother has more, but I need to get under her bed and organize her photos (a hard thing to do when I'm there so rarely and for such a short time). Above, you're not seeing things—that's me as a heterosexual crossdresser woman in fourth grade, 1978. Behind me is my buddy Stephanie, who was my "crush"/friend (and who is now as gay as I am, in reverse). P.S. Michigan had the coolest bicentennial plates!
Below is me as a werewolf in 1981, exactly 30 years ago. I was proud (and remain proud) of my ability to curl the corners of my nose animalistically:
Other costumes I recall include Scooby-Doo, maybe Underdog, maybe Superman, a hobo (Vaseline on the face, coffee grounds on the Vaseline) and Groucho Marx (modified hobo).
