If you're going to use great kilts, remember that there are several different ways to wear the upper half... Use variety among your actors so that the kilts look more natual and less like costumes or uniforms.

I did theater in high school, and among other things I did alot of set and costume work.

We did "15 minute Hamlet" and we had a blast. I player the part of the grave digger, who is described as "a mysterious foreigner," and I wore a kilt, since we weren't going for historical accuracy, but decided to just have a blast with it.

Have fun!
