How to put it together

1
Cut a horizontal slit across the back of the oversized shirt, wide enough for your torso to slide through.
2
Construct a cardboard frame shaped like a human pelvis and insert it into the waist of the jeans.
3
Stuff the legs of the jeans with fiberfill or newspaper to make them look like real legs, then secure a belt around the jeans' waist.
4
Attach the stuffed jeans and cardboard pelvis to a harness or a modified backpack frame that sits at your side or front.
5
Put on the oversized shirt, slipping your actual upper body through the back slit so the shirt drapes over the fake lower body.
6
Apply red paint and fake blood to the cardboard 'cut' area where the body appears to be severed.
7
Adjust the alignment so your real upper body looks like it is floating next to or above the stuffed legs.

Makeup & hair

Keep your hair and makeup simple, or go for a shocked, pale complexion using white face powder and dark eyeshadow under the eyes to match the horror of being cut in half.

Half Body for couples, groups, kids & more

couples: One person dresses as a mad scientist holding a saw, while the other wears the cut-in-half costume.
group: A magic show theme with a magician, an assistant, and the volunteer cut in half.
kids: A simplified, non-gory version using a box painted like a present or a table to hide the lower body.
Plus size: Use extra-large shirts and wide-cut trousers to ensure the cardboard frame has plenty of room to sit comfortably.

Tips

Keep the stuffing lightweight so the costume isn't too heavy to wear for several hours.
Practice walking in a mirror to ensure the fake legs swing naturally and maintain the illusion.
Wear dark clothing underneath the split section to help hide your actual legs in low-light environments.
