WoW!! Thank you EVERYONE for giving me some great ideas! I'm the sort who likes to think things through and consider experienced opinions before I take on the district. I would like some California legal precedents to point to. The school is great. The kids and staff have been very good to Mark. The rules at school are strict against bullying and the general dress code is strict and enforced. (No low-hanging pants, no drug or alcohol ads on clothing, no bare midriffs or spaghetti straps or excessively short skirts.) These are things I have appreciated through the years of having 3 sons there. I would imagine some of the staff at the school level would probably like to make an exception--or clarification--to the rules as they might pertain to kilts, but experience has shown me that officials feel safer saying no to exceptions. With good documentation and proof of other rulings, I think it makes saying yes a lot easier for them.
Mark is not talking about wearing a formal kilt to the prom with the other kids, and yesterday I told him he needs to keep it quiet until I get things worked out. He asked for this kilt for Christmas, but not in time for me to make it. I have promised the kilt as his delayed Christmas gift and he is really excited about getting it! My grandmother was a MacDonald and Mark's Dad is a Hay. We are definitely of Scottish heritage and Mark is developing pride in that.
