Most Americans are totally oblivious to proper kilt attire. I was oblivious until I found XMTS and started to learn from everyone. Hey, if you have no reference point of proper Scottish dress, than one will do whatever they learn from movies, TV, people around them, etc. That becomes the norm; that's, now, acceptable. It's like a child growing up in a house with violence...that's what they learn. Well, most homes in the USA do not have kilts or any inkling as to what is proper. So, wearing a kilt becomes whatever you want it to be, sorry to say.

As for wearing the PC/kilt at a wedding, well, yes, check with the bride. However, if people expect it, then go for it. I see nothing wrong...life is what you make of it, and if you show up at a wedding in a PC/kilt, well, the world is still gonna spin.
