I made this costume for the NYC Halloween Parade in 2009 - it's a Picture Strip from a Photo Booth, featuring 3 silly pictures of me (enlarged to life size and mounted on Foam Core) and "live" box with my face, all wearing the same outfit and mugging for the camera.
Various sized wooden dowels and flat wood trim pieces
Long, Flat Aluminum Bar Strips - at least 5 feet tall
White and black Duct Tape
Black Foam Core
Starched cheesy background Curtain
Silly Enlarged Pictures of yourself wearing the outfit you plan to wear on Halloween
Large white pieces of foam core for mounting pictures
Foam Rubber Scraps for comfort padding
2 screws to connect shoulder arms to aluminum strips
Battery powered light strips (optional)
First, I made a tacky orange curtain that I ironed and starched "accordion" style for the backround in the pictures, and then posed for some silly faces shots with the curtain behind me and wearing the outfit I planned to wear on Halloween night (pay close attention to the weather!). Once I picked 3 pics I wanted for the picture strip, I enlarged them and printed them to life size, then mounted these onto foam core.
