Halo 3 Halloween Costume - $20 (Colbert)
I have a Halo 3 Master Chief Costume. I paid $65. for it last year on ebay. It is an adult size. My twelve year old son wore it last year but it was too long for him but the legs gathered at the top of his boots so it worked just fine. It would fit a slim adult up to 5 1/2 feet tall. Included is the costume, helmet and arm guards.
