Tara Bordes played a Klingon child in the Voyager episode "Prophecy." This costume is wonderful in the simplicity of its appearance, and yet it retains much of the complexity of the adult versions. It was originally created for use in the DS9 episode "Rules of Engagement" when Worf sees all the dead Klingon children, but this one never made it onto the screen until Voyager. It is featured prominently in the scene where the Klingons come aboard into the cargo bay. My oldest daughter loves this costume and hopefully she'll get a chance to wear it to a CON some future year.
