Tear Dress

So I was interested in perhaps making a tear dress, or something similar, anyway...

Found lots of neat information online. Doesn't seem so difficult, it fits with the way I sew already. But here's my problem. It's with this: "The Official Women’s Dress Of The Cherokee Nation of Oklahoma" link There's a long list of rules!

Hope I don't upset too many people if I make my own version of these tear dresses, but don't follow all the rules. I mean, it never was authentic to begin with, fashions change, tastes change, and NOBODY tells me how to dress. I really love the style, it certainly looks easy enough, and most definitely comfortable! Plus, it would go nicely with my aprons.
