John Cena

• For a John Cena costume, combine a child-size shirt with John Cena on the front, long blue jean shorts, and a baseball cap adorned with Cena's logo. The outfit is finished with blue wristbands. Fake muscles can be created by stuffing the shirt or buying fake muscles at a Halloween costume shop. You may also find the full costume at a Halloween costume shops.
  
  

The Undertaker

• Dressing up as the Undertaker does not require brand name purchases. You can easily create it with a long black jacket that reaches the child's ankles. Include a long black wig worn underneath a brimmed hat. Black jeans and a black muscle shirt completes the outfit. No face makeup or mask is required.
  
  

Stone Cold Steve Austin

• Because Steve Austin is bald, a child dressing up as this character will require a skull cap. He often dons a mustache, which can be purchased at any local costume shop. Dress you child in a black vest with Stone Cold's logo on it, as well as a flesh-colored shirt underneath to keep the child warm (Stone Cold typically wears the vest with a bare chest). Blue pants and sneakers complete the outfit. This outfit can also be found as a complete set at Halloween outfit supply stores.
  
  

Rey Mysterio

• The child's Rey Mysterio costume is one of the few costumes with a mask. The mask is a white and gray full-head mask. The wrestler does not wear a shirt, so a flesh-colored shirt decorated with the wrestler's signature belt is required. Floor-length white pants and sneakers finish this outfit. Make sure the child can walk without tripping and can see fully from the eye holes in the mask.
