Arlen, you are absolutely right to wear what you want, when you want. It is really obnoxious for any person other ( related or not) to tell you what to wear. My impressin is that you will ignore this person and go with your own intuition. Good on you.

I live in a "hard" working class area of North East England and I get a bit of friendly banter from people in my local pub, but NEVER get any insults or anything like that.

Keep it up.

By the way, I have a blue denim kilt from Kiltstore, which is just fabulous.
