This is the Star Wars Ewok Knit Hooded Scarf available from ThinkGeek. It costs $25 and kind of makes you look like an Ewok. I say kind of because I can still tell the girl in the picture is human. I am a detective. Besides, you don't want to look too much like an Ewok anyways or the stormtroopers will come after you. That's like dressing up as a deer and playing in the woods during hunting season.
Keep going for a shot from the rear in case you were worried it has 'KICK ME' embroidered in it or something (it does not).
Thanks to Elizabeth, who asked me to buy her one. No you buy me one!
