I know I have seen this mentioned before but I believe it is really important for keeping old content viable and people interested in endgame fashion wars! The current model of putting a look ON a piece of gear is obsolete, instead just let us put the piece we want the look of in a separate item slot. Just have 2 slots side by side, stat gear, and appearance gear. This would not only make it a smoother less bothersome task to equip new looks, but would also free up inventory space.

Speaking on inventory space, there should also be a bag similar to the key items bag for gear, just an unlimited space to put whatever looks or even presaved templates we want. I don't know the slightest thing about how this stuff is created, I just think ease of use when it comes to character customization is important.
