1. Amy Winehouse's Ghost. If you're into really looking terrifying for Halloween what better way to start. Amy looked like a walking corpse a long time before she kicked the bucket, so you wouldn't even have to work so much on the 'undead' look. Just pale yourself up a bit, it helps if you're seriously thin, and then do the beehive hairdo and the Cleopatra eyes. Or you can come as her date and bring a beehive wig duct taped to a broomstick.
2. Casey Anthony. Now this is going to get even the liveliest, friendliest party all riled up. Get the big fly-eye sunglasses, a notebook, and a smug look on your face and if you want to go balls to the wall tasteless you can get a doll, cover it with death paint and scream 'not guilty' into people's faces.
3. Melissa Gorga. For those of you not in the know, Melissa was a new edition to the Real Housewives of New Jersey clusterfuck being Teresa Guidice's sister-in-law and also the youngest and prettiest of all of them. So this one is easy, as much body glitter and fake tanning as you can find, a really skimpy outfit and try to self-autotune your voice whenever speaking. Also, it really helps if you carry around a book that you've made a hard cover of that reads 'I Advocate Marital Rape'
4. Don Draper's Conscience. This one is easy. Just wear all black, or a cape and say it's an invisibility cloak because he doesn't have one. Get it?
And I just had to leave you with this...
