Maleficent

If you want to make an inexpensive diabolical Disney diva, here's how:

Simple take some pipe insulation - which you can buy at your local home remodeling center

And slit it up the side.

Then slip some wire up inside to form it and use duct tape to attach it to a headband.

 Then you can thicken the "horns" with more pipe-wrapping and wrap it in duct tape.

Then either use a swimming cap or slip a baggie over your hair and cover it in duct tape.

You can touch up the widow's peak by using makeup. You can also highlight your cheekbones to accent them. Then simply add a black cape and some wings.

And wah-lah...Maleficent
