Might I suggest that you approach your direct supervisor and discuss it with them? That is how I handled wearing a kilt to work. I first went to my manager and indicated that I wanted to broach the subject with HR and get approval to wear it. He was fine with it. It moved a little too quickly for him because the first day I wore it we had a United Way presentation from the very senior management and I was in the front row, by chance not design. So I was immediately seen by all and no problems. Most of the fear is in our own minds, at least that has been my experience.
