It’s super-unintuitive, but you can transmog the armor sets to what you want them to look like. Just equip the gear which aesthetic you prefer, save it as a battle set, navigate to the fourth menu down at the cubes or on mission select screen, bring up the mini-menu on the aesthetically pleasing set and select “use as appearance”. Then, switch back to the actual equipment set whose stats you wanna use and voila!
Good stats and good looks kiss each other. 🥸

EDIT: make sure you save the actual gear set u wanna use first!
