I sometimes have to wear an orange hat with it.
The orange gear is part of a uniform so the "rules" of civilian highland wear don't apply. At least in my opinion.

And yes 1'500$ seems about what you will pay for a chunk of kilt caboodle. Then some people spend that and much more on a watch that is in essence the same as a 70$ swatch in a metall shell.

Compared to that Highland wear does seem more reasonable to me.
