Put on a long old t-shirt and start wrapping yourself in duct tape. You will need someone to help you when it comes to the upper back. Make sure to do a few layers of tape.
Once you are completely covered in duct tape have a friend cut it off of you from the middle of you back all the way down.
tape up the cut area and start to fill with batting.
I had a stand home that worked perfectly so all I did was tape some cardboard onto the stand the fit the form on top
( The chest area was not big enough so I added a bra with padding to enhance it)
I then decided to cover the duct tape form in fabric so I used a pillow case and sewed up the sides.
You are now the proud owner of a dress form in your exact measurements!
