Cereal Killer

• Dress up as a cereal killer for your next costume party. Choose regular clothes for the base of the costume, such as a pair of jeans and a T-shirt. Cut the labels from different boxes of cereal. Stab each label with a knife, or use a pair of scissors to cut them in their centers. Use red paint or fake blood to make it look like the label is bleeding. Pin the labels all over your clothing.
  
  

Pregnant Prom Queen

• Go as a pregnant prom queen to your next Halloween party. If you are pregnant, this costume is simple. If you are not, tie a pillow around your middle, so that it looks like you are pregnant. Choose a large formal dress from a thrift store and wear it, along with a tiara and a prom queen sash. You can make a sash using a wide piece of ribbon and a glitter pen.
  
  

Cheating Politician

• Cheating politicians have long been a fixture in the news, so use that as inspiration for your next Halloween costume. Dress up in a suit and comb your hair, so that it looks like a typical politician. Then, carry a folder with "budget" or "legislation" printed on it, but have a flier from an escort service hanging from your pocket. You can make a fake flier using a computer.
  
  

Oil Slick

• Oil spills are serious events, but try to put a humorous spin on it for your Halloween costume. Dress in a completely black outfit and paint any exposed skin black. Cut fish shapes, crab shapes and bird shapes from poster board and pin them all over your clothing.
