You'll have no trouble finding a variety of costumes portraying each character online and in stores. Or you can create your own take on the popular figures. To make your own version of good guy Luke Skywalker's look, dress your young Jedi knight in brown pants and a brown shirt. Top it with a black tunic and black knee-length boots. Hand him his very own light saber (available at toy and costume stores) and he's ready to do battle with the Dark Side. May the Force be with you!
