This item is made to be worn over the heavy red suit the gorillas wore, so it is an extra large and would fit around an approx. 38" waist, but there are snaps and Velcro for adjustment (you can make it bigger or smaller, but I do not know the limits). It has some ape fur sticking out from the sides.
This is battle armor that was used during filming. It shows some wear and soiling from it's days on the battle field. You will receive the exact item shown in these photos. Inside, you can see the name of the actors who used this during filming, but I can not read them. I can make out two numbers: 65 and 727.
