I used to have a Vader mask, and the rest of my costume was a black Houston Astros t-shirt (inside out, of course), black pants, and a green lightsaber (because I already had it and my parents wouldn’t buy me another one just for the colors to be right).
The closest thing I ever was to a Jedi was a Jew wearing a bedsheet (and Heelys) waving a palm branch and pretending to worshipp an actor portraying Jesus in a church play in '03ish.
