This is the Homemade Lego Man Halloween Costume I made. I sat and scaled out the measurements from an actual minifig. The whole thing is constructed from cardboard, foam, duct tape, and camping mats. You look through the mouth. The leopard print is duct tape. I looked through a boatload of paint schemes and picked the ones I thought were best for comedic purposes. It stands pretty tall so doorways were kinda hard but my buddies ran blocker for me. With no one in the costume it can stand on its own.
The look on kids faces were priceless on Halloween when they came to the door.
