I'm sure most would be fine with it. There are always a few who won't budge from the old ways, but it's best to ignore them. That said, I will admit that I don't personally like non-traditional kilts. But that's just it: it's a matter of personal taste. Wear what you'd like to wear. It's your wardrobe, and your choice. I'd love to see more men wearing non-trad kilts, but you'd never catch me in one.
