Here is my son as a Siamese twin. He has 2 arms 3 legs and 2 heads, but one body. Home made and looks awesome, very cheap to make!
The costume took a couple of days to complete. I picked up two pairs of pants and two button up shirts at the thrift shop. I had also found a Styrofoam head at the thrift shop. First I wanted the twin to have two legs one leg was half and half, works best with two different colour pants, and one leg was stuffed, a lot of sewing involved in this project.
I secured the head with a quick tie to the collar then stuffed the second side. My child’s arms went through both sleeves. I found two cheep masks and used two touques to cover their heads.
He had fun at his school getting the kids to figure out which head was his. He also won a costume contest at a party he went to. Hope you enjoy the idea and have fun creating your own siamese twin little monster :-)
