My daughter decided she wanted to be an evil tooth fairy. Not just the tooth fairy, the EEEEEEVIL tooth fairy. She wasn’t really sure what that might look like, so I took a bit of liberty with the design. In the name of modesty, I opted for pants and top in lavender broadcloth, made from a pattern that was designed for Princess Jasmine, and layered a leotard underneath in case her top slipped up.
I cut out a felt tooth, gave it a grrrr face, and stitched that to the front. I purchased wings and antennae, then glued a felt tooth with a grrr face to the top of each one. Just to make it extra special, I made a white fleece tooth with red felt wings (decorated with strips of purple felt and little teeth on the bottom to cover some of the stitching) and gave it a grrrr expression.
And voila, she went from little girl to the cutest Evil Tooth Fairy DIY Costume ever!
