Nothing says Halloween like a Jack-O-Lantern or Pumpkin costume. Carving Jack O Lanterns began in Scotland and Ireland where they originally used turnips instead of pumpkins. They were set up on front door steps to keep evil spirits away. It was not until immigrants came to North America that people began carving pumpkins. Now you can carry on this tradition by becoming a funny pumpkin, a scary Jack O Lantern and more with these pumpkin costumes for kids and adults.
