Wish I had taken pictures during construction but I put this together 15 hours before Halloween so I had a deadline! The parts I had already were a green leotard, green metallic leggings, some old boots (seen here covered in duct red duct tape) and a red boa for sex appeal.
I bought silk leaves from Michael's to cover the leotard so it had a poison-ivy / piranha-plant look to it. These were then glued on or stapled (depending on the look). This picture was taken after Halloween so some of the leaves have fallen off. Glue worked better than staples.
The most important aspects of the mask are that it is lightweight and durable, and you are able to drink through it. I used a black mesh inside the mouth so no one could see my face. There's also a hole in the mesh so a beer bottle can fit perfectly and I don't need to take the mask off. The teeth are made of folded posterboard.
