My armor is constructed entirely of cardboard. This is not corrugated cardboard but more like the kind you would find on the bottom of a yellow legal notepad. I downloaded an image of an actual Knights armor and used that as a starting point. All of the cardboard to cardboard connections are made with two different size brads which make it look like rivets.
To prevent absorption of sweat and paint, I sealed the entire costume with an Elmers glue and water mixture. The paint is Rustoleum Hammered Silver which gives it a great metal appearance. The costume consists of seven individual pieces and has to be put on in much the same manner I would assume real armor would have to be dawned. Legs/foot coverings, arms, body/skirt, helmet and then the collar are put on in that order.
Velcro is used to attach sides of body/skirt, backs of the legs and the neck part of the helmet. The fleur-de-lis is pasted onto the breast plate and then drops of glue added around the edges for the rivet appearance.
I began this Homemade Knight In Shining Cardboard Costume at the beginning of October and worked on it an hour or two almost every night until Halloween.
