The appearance of tartan kilts in ireland before the late 1800s nationalist movements is heavily debated. Most clothes before that era were reflections of the class people were in, thus potato sack clothes.
Regular kilts were however used in solid colours, thus any pleated skirt dyed a dark colour will suit your needs. (:
edit: much like my eyebrows, scottish and irish cultures are sisters and not twins. I have no objection to scottish glams being added to the game, go nuts, i hope you get your request.
