I never really asked for permission. The Jews, Arabs, Africans, all other ethnic groups, wear their cultural items. I did get some resistance from one of the company owners at first, so I told him that if I couldn't wear my kilt, I would make a cultural discrimination complaint with HR. That did the trick. He's now mad at me again, because his fiance wants to have a Scottish wedding because of me. He refused, and it apparently caused a little friction.
