Wipe off any oil from your eyebrows with some alcohol.

Get a glue stick and glide a little bit on your eyebrows in the opposite direction of hair growth.

Brush eyebrows smooth.

With a little spatula (you can use a plastic one, a wooden one, a butter knife, a manicure stick, anything smooth and flat)scoop out a little glue and and smooth it over your eyebrows. Let dry (takes about five minutes or so).
Repeat until hairs are completely covered.

Using a waxy white pencil (I used NYX Jumbo Eye Pencil in Milk, you can also use white concealer, or face paint)go over glue, covering eyebrow completely.

Go over the white pencil with some setting powder, you can use baby powder too.

Now cover your eyebrows completely with a concealer then go over your whole face, including lips, using a pale foundation. I used a very cheap crappy one I had on hand; if you are going to do this look to go out, I suggest using a good foundation and concealer.

Using a very light lavender eyeshadow cover your eye area all the way to the top of your eyebrow.

Cover your eyelid with a shade of lavender just a bit darker than the highlight.

With a thin brush, go a bit above your natural crease using a medium shade of purple, be sure to go from the end of your eyelid all the way to where the tear duct is.

Now, repeat previous step with a deeper shade of purple, going above the lighter shade. Extend color going towards your ear and at the tear duct.

Repeat the same process with a very deep shad of purple above previous crease. Blend this color underneath the eye.
I also drew on the eyebrows using a brown gel liner (I find that those work best for fake eyebrows)and an angled brush.

Using the same method, go above the previous crease using a black eyeshadow.

Now line your eye with some black eyeliner extending into the black eyeshadow, so that it sort of disappears into it. Again, I used black gel liner.
I also used some brown eyeshadow on the sides of my nose to make it seem a bit thinner and longer, like hers is.
In addition to this, you can make your nose seem sharper by using a black pencil and "draw" your nostrils in a triangular shape.

Next put on some false eyelashes. I think thicker ones would look nicer than the ones I used.

For the mouth I used a deep red lip liner and made the top and the bottom lip shape sort of match and extended it a little past where my lips end (lengthwise)
She has got a very weird mouth!

I then drew in a little peak at the top of my head with some black eyeshadow.
You can skip this step if you have a costume.
I was trying to look sinister, but it didn't work out. lol.

I put on a hoodie just to show what it could look like with the head covering.
