This is a good article, but it is hard to call these the definitive Apache clothing styles because there are so many tribes that fall under the umbrella term "Apache".
There are at least seven languages spoken by different people who are called Apache. They are related, but not as much as you might expect.
Mostly they did all wear deerskin because it was the easiest material to make, and they could be distinguished by their beautiful beadwork.
But other ornaments would depend on the tribe and what was available in the area.
