We need an interface window - Glamour Collection - to free up inventory!

[Felis]

Servers, limitations, saving character data, yada yada yada

Been asked for since glamours were first introduced it won't be happening anytime soon

Depend of how the catalogue would work
If it allow to try on every gear ingame to find the right combinations (only to try on, for glamour you will still need the gear), then it will be not part of the character data, but with the gear database of the game.
It don't have to be ingame anyway. It can be also a Lodestone function.
