I can't think of any examples to bring up right now, but it would be difficult to judge since ornamental armors were easy to distinguish since they were, well, ornate and not designed to be practical. That applies to practically every fantasy armor so I wouldn't know how we could create a system, or really why we would bother, to distinguish between ornamental, or dress armors, and regular fantasy armor.
This might be easy and sensible in real life, but makes no sense for tagging purposes.
