My body double idea

For my first project I want to create a sculpture of my mid-torso area (around the waist and hips). It would be covered in paper mache and then painted. I am not yet sure what the base underneath will be, but at the moment I think chicken wire might work. I would then put some body measuring tape around the waist. This sculpture would represent issues I have with my body image. However these issues are not always present, which is why I would like to be able to move the measuring tape so that it is used and then put down, which would also make this sculpture "functional". (I haven't thought of any ideas on how to achieve this, and I don't know if it would be possible in such a short time frame.)
