My friend decided to go ALL OUT for Halloween, and this is what we've come up with (I'm such a dork I'm being ginny weasley...)
THE VAMPIRE BELLA:
...HAIR: Straight, dark brown hair that goes all the way down the back.
...SKIN: Mix greyish-white body paint with very fine sparkles and paint your exposed skin. Brush translucent powder over the dried paint to make it more natural and to protect it.
You can substitute the paint for powder, but there's a bigger chance it'll come off. If you want, you can also use white body paint that reacts to black-lights, instead of sunlight.
To avoid doing your legs you can wear white hose. Also, you can buy full white body suits.
...TEETH: Whiten your teeth, it you have time, but if you don't there are places that sell temporary, translucent white tape you can place over them.
...LIPS: Its best if you wear grey lipstick. Can be found in costume stores.
...NAILS: Paint them white or red. the red looks nice against the pale skin.
...OUTFIT: My friend made a short, simple ice-blue dress out of fake silk that looked ripped up the sides, and she wore dark-blue stilettos that she found at a re-sale shop.
