Wanna Glam it? Play it!

I never said anything about "modern" casual. From what I've seen, at least 2 of the pieces you listed are most often used to create a casual look overall, a.k.a. it's not armor and certainly not something you would actually wear on the road or in a fight.

The problem is, as I think I understand it then, that "dancer-appropriate" gear is at odds with anything you'd sensibly wear "on the road or in battle". It's light and showy, or you sacrifice the dancer-ness to look practical and that brings you back to wearing archer/machinist gear because those are the jobs whose basic concept overlaps better with travelling gear.

What style are you envisaging for your dancer that looks both dancery and battle-ready? Because I honestly don't understand what you are thinking of. None of the shirts look casual to me so I don't know quite what you're meaning by the term.
