Glam Dresser is inadequate, even doubling it does not solve the problem.

One thing that they should be able to add is a new collection log for attire.
I would make it something like this:

Complete Shisui of the Violet Tides 20 times as a DRG or RPR - Unlocks the Shisui Maiming glamour.
Same is for MNK+SAM, NIN, tanks, healers, ranged, casters.
For alliance raids it would also be 20 times, while 8-man raids need 5 times per turn.

When using the glamour plates, you have the Armoire option and the Attire Log option. The log will function the same way as the Armoire where you can pull the glamour over to the plate. Only difference is that you can't pull gear out from the Attire Log.

Doing this, it would allow you to skip putting dungeon and raid gear in the dresser, saving some slots.
It's also a system that I think should be relative easy to make for FFXIV.

In addition to this, they should also link relic weapon vendors to the same system so you don't have to go to 4 different areas for relic glamour repurchases.

A different option would be to have the entire gear-set equipped and then talk to an NPC to register it (Similar to what we do in the Garo event) and that then completes the Attire Log, this would also make it easy to include most gear-sets in the game.
