Yep, it's nearly that time again. Beggars at your door, scantily-clothed girls roaming the streets, and a dozen different parties hosted by people trying to recapture their youth. Halloween is at the end of the month, and there's a good chance you're going to need to come up with costume ideas soon. The tradition of Halloween has been going on for centuries across the world, although it was only in the early 20th century that it began to resemble the festivities we have today. Pumpkin carving, apple bobbing and bonfires are all widely partaken in, but the most famous tradition is dressing up in costume. There was a time when Halloween costumes actually meant dressing up as something scary, although the definition has since become a bit lax. These days, you're just as likely to see a group of mini-skirted cowgirls on Halloween, as you are a gang of ghosts and ghoulies. In the spirit of Halloween, this list takes a look at 21 totally genius Halloween costume ideas to get your creative juices flowing. From your favourite television characters to some truly horrifying face paint work, at least one of these entries should get you inspired!
