I want to be a Tree!

Part of Halloween is the chance for stores to sell more stuff, including loads of candy and costumes. I never fall for it, although sometimes it's difficult. This year I would like to be a tree using only items found in my house. At the moment I've come up with pretty lame ideas. Brown shirt, brown corduroy skirt, green leaf print jacket, and brown nylons/stockings/socks. I have really long hair so that may be an asset if I can figure out what to do with it. I do have some gel, but I wouldn't know where to begin. I've posted an article before with a similar request but the comments included items I would have to buy at Michaels or a place like that.

If you have any ideas please help me.
