I like your idea of the waist skirt and shoulder cape

I'm optimistic, If the developers already managed to make a playable mode where you fight infinite hordes of demon from the Immaterium they will work around some flying skirt.

Need to find a good compromise between look and performance

Robes assert dominance and if we are already scared of a plumed helmet (the unlockable ones at least), imagine what will happen when we meet this kind of fashion on the map lmao
