Here are some basic rules I have worked out. Maybe we can work on a color-coding scheme, as suggested. No footwear in the orphanage. No fighting outside of training. Lights out by 10, wake up at 5. Boys and girls must stay in their own dorms at night. Do not lie, cheat, steal, or tolerate those who do. Do not leave the orphanage without a pass. Clean up your messes. Do not destroy the property of the orphanage. We also need to work out a schedule, come to think of it. As for the dress code, I'm thinking that it varies a bit from race to race. Goblins and kobolds would probably not use as much as, say, humans or elves. So, there would be a relatively low (but still decent!) minimum. And it would vary between the boys and girls, of course. There could be a range of options too.
