Santa is a prominent figure representing Christmas and gifts. A red shirt and red pants will be worn by the Santa character. Any pillow can be used to show the big belly associated with Santa. Santa wears a hat and has white hair and a white beard. The hat can be purchased at a minimal cost. Cotton is appropriate to use for hair and the beard. Black boots or shoes and a black belt will add to the detail of the Santa costume.
Make your reindeer costume choice brown. Brown shirts and pants will represent the body of the reindeer. During the Christmas holiday, headbands with reindeer antlers will be available at some stores. Use face paint on reindeer characters, and paint the whole face brown. Paint red on the nose of Rudolph, and black on the nose of the other reindeer. Add a collar that will be worn around the neck of the reindeer character. Also, display the large hooves of the reindeer by wearing big black shoes and mittens.
The majority of the elf costume will be green. Have elf characters wear a green shirt or jacket and green pants. Instead of pants, elf characters can also wear green- or red-and-white-striped tights. Elves wear hats and have big ears. During Christmas time you should be able to find a hat that has fake ears attached. This will be a perfect accessory to show your character as an elf. Elves wear pointy shoes, and these can be made by covering tennis shoes with green felt in a pointy shape.
The character roles of children should most obviously be played by children. Christmas skit scenes including children will often be set in the home on Christmas Eve and Christmas Day. Children will commonly be seen wearing pajamas because they will go to bed early waiting for Santa to come. Pajamas can be Christmas themed, but do not have to be. Slippers and robes are accessories that can be worn by child characters in the skit.
