Each year at University there is a huge medics social event where older years can dress up fancy dress, the more creative the better.
Last year our theme was movie characters and I chose a Treebeard The Ent from Lord of the Rings Costume
I sewed a smock shaped top from two sheets of brown material then added strips of brown and green material, and some leaves and branches from the bushes at the back of our house to the costume. I wore brown tights underneath. To make myself taller I added a washbasket on top of my head which was strapped on and covered in brown material and decorated as with the top. It had a small hole cut out of the front so i could see out and I painted my face brown/green so I was camouflaged.
I had to get a taxi to the venue as it was difficult to walk in, but this added to the “Ent” appearance.
I thought you where trying to make an “Ent” costume not “Return of the Swamp Thing” Treebeard had shape and a face. Think you need to watch Lord of the Rings again.
