Tips: (More coming soon) *Have an escape route-- What could be worse than not having a convient way to get into and out of your costume in emergencies...
*Be careful when chosing-- Not only your character, but your products too. Halloween wigs are crap, and certain materials might look different on humans than they do on your tv.
*Remember your budget-- If you want a costume to be realistic, it might take more money than you had expected to spend. Some people spend thousands of dollars on a single costume.
