Lots of people choose this costume because it is scary and really fits in with the Halloween spirit! To make a zombie costume, all you need are some old clothes which you will never use again and tear them up in various places. Add a bit of fake blood to the clothes if you want. Cover your face in white eye shadow or face paint, and use black eye shadow to give you eyes a hollow, tired effect. Use a bit of fake blood to drip out your mouth if you want. To finish the look, add some white contact lenses.
