We got the idea for a headless costume from others on your site. I bought a $5 large man’s jacket from a thrift store, plus $8 for 2 plastic hands you can get most anywhere around Halloween. I used a large backpack & stuffed a pillow in it so it stuck out above the backpack, I found 2 pieces of plastic pipe on either end to make the shoulders a little more rigid.
The arms of the coat were stuffed with newspaper. I stapled the plastic hands to the wrists of the coat. The neck was a sour cream container that I taped to the pillow & then covered with a cut sleeve from an old white shirt. I used red fabric paint to add blood to the neck & coat. My daughter simply slipped the backpack on and we did the coat up, leaving a button undone for her head to come through.
The best part of this costume was that this coat had side pockets, so I was able to cut the insides of the pockets out & with my daughter wearing black gloves, she could put her arms through the pockets to hold her treat bag & no one really noticed her arms since they were black like the coat. She was a huge hit & total strangers stopped her to ask if they could take her picture.
LOVE THIS!! We will definitely be making this for our 10 year old this Halloween! She will be a big hit in Barrie!
