Sounds kind of like Lord of the Rings Online had. You made up to 7 different outfits that you could switch between at any time, and then of course the 8th slot was the "gear" look so you go back to the appearance of the gear you had on if you liked it. Plus it was all dyeable, and appearances can be unlocked/stored indefinitely in your bank so you never had to keep it on hand anymore. This is a game much older than XIV and had a way more robust cosmetic system.
Either way, I want to see what Yoshi has in mind since they mentioned something about glamours and recalling appearances in the last live letter. All I know is, if I can't have different looks per gear set rather than the gear itself so I can finally make my jobs look different, I'm going to be pretty upset.
