I wanted to come up with something original and had never seen a tin woman so I went for it. I found the boots at a yard sale and spray painted them. Found the dress and silver leggings at a hoochie shop in the mall and the wig at a Halloween store. I hot glued the wig to a funnel I had spray painted silver. I used silver hair paint and painted any skin that was showing and used silver eye shadow on my face. Found a heart necklace in my costume jewelry since that is what I was going to see the Wizard of Oz for.
And of course I carried around my oil can in case of emergency! The costume was a hit and definitely original. My husband went as the scarecrow in overalls and a flannel shirt with a little hay sewn on the top it off.
