A very simple costume to make for either you or your kids.
Directions to make this Halloween costume:
Get an old lab coat or scrubs from a used uniform supply house.
Get a face mask from the drug store or make one from material.
Take red fabric paint and smear it on the lab coat or scrubs and face mask.
Get a pair of latex gloves and use a permanent red marker and color the gloves.
Make a name tag. I made my daughter, "The Doctor of Death".
Use red face paint so it looks like there is drops of blood on the face.
Accessorize with a stethoscope and needless syringes if available.
