One says the kilt is clothing, I wear clothing as part of my Halloween costume, therefore there is nothing untoward in including my kilt as part of my Halloween get up.
That pretty much sums it up for me. Halloween this year falls on a Wednesday. I will be working. I will be in costume. That costume will include a kilt. I can't prevent someone else from getting offended by it, nor will I worry about it. I'll post pics.
