How do i make myself look awful?

Halloween thing :P My school does a haunted house every year (grade 12's set it up, I'm excited :P )and I'm suppose to dress up as a sick kid, not dead yet, but dying. They didn't give me any restrictions but I do have to wear one of those hospital...

gowns. What else could I do to make me look worse :P ?
Hair, clothes (under the gown), make up, etc..

get white power, reddish orange eye shadow (make sure you go from darker to lighter as you go from the lid to eyebrow).
use red eyeliner
On your knuckles and joints, use a grayish powder.
define your collar-bone with the same tone powder.
also use grayish powder instead of blush.
give your lips a bluefish purplish tone.
put some pinkish reddish powder on your noise, don't over do that, you don't want to look like Rudolf, just like you've blown your noise one too many times.
use jell and start brushing jell in from the underside of your hair, then just start messing it up, tease it.
perhaps get a spray bottle or something and lightly mist yourself with it to give you a sweaty effect.

you'll look like your on the verge of death.

you can also buy these fake scar tattoos to give it an extra boost
or if your good with theatrical fake blood, you can use paper towels and fake jell like blood to give yourself gashes

get a pale powder and useit as fondation. Use an ashy purple eyeshadow around the eye area especially under the eye to give your eyes a sunken in look. Use the same eyeshadow where your cheekbones are to make them look sunken in too (practice this to make sure you know how to do it and it look real, if you can't figgure out how to do it, skip this step.) use a pale nude lipstick to make your lips look pale as well. You can put a little of the foundation on the lipstick to make it look paler, but don't over do it. I'd suggest making your hair look greasy and tangled. Tease some of your hair to make it look tangled.You can take a cotton ball and a little bit of baby oil (or any other oil, it doesn't matter) and apply it to your roots.

I forgot, you can also use a red-ish purple eyeliner as well. Hope I helped. I learned how to do this when I did make up for a school play. Funmail me if you have any questions.
