This year, princesses once again took the crown as the top costume choice for kids (10.7%), with Spider-Man following in second (4.8%). The third most popular costume, a pirate (4.7%), is undoubtedly inspired by the hit "Pirates of the Caribbean" movies. Fourth and fifth place go to age-old Halloween standards, a witch (4.2%) and fairy (2.8%) respectively.

Television shows and movies are once again the inspiration for many hot children's costumes. One new addition to the list this year is Disney's Hannah Montana, who comes in at 23rd on the list, immediately followed by everyone's favorite boy wizard Harry Potter.

But Halloween isn't just for kids! Nearly 60% of consumers are planning celebrating Halloween in some way or another, which means many adults will be joining in the revelry themselves. One-third of adults (33.8%) will dress in a costume this year, and of those almost three-quarters (74.8%) already had a costume in mind last month. The top five choices for adults were all a bit more traditional: witch (16.9%), pirate (3.8%), vampire (3.1%), cat (2.5%), and princess (3.8%). Other adult favorites include Star Wars characters (1.2%), doctor (0.9%), and an athlete (1.0%).

Figures and data were collected by the National Retail Federation (NRF) for the NRF 2007 Halloween Consumer Intentions and Actions Survey.
