SunlitGrove and JenF on the Glamour Dresser for the BLACK MAGICK to make this possible. Check SunlitGrove's asymmetry here, they've upscaled almost every chestpiece in the game. (https://www.glamourdresser.com/mods/asymmetrical-chestpiece-collection) Kirara for TGT and model edit. SE for model.

Midlander bodies and variants (Elezen, Miqo'te) only by default, but you can probably port it pretty easily.
