I simply cannot fathom your 1) love for the current glamour system and 2) hatred of any change.
Here are a few examples of intuitive UIs that provide a simple, easily searchable storage of looks.
Rift: Click armor slot, select appearance, apply. Can filter by armor/weapon type. Easy application. Can save favorites. Searchable interface. Saves multiple sets you can swap at will. Dye interface not shown but similar (Rift has both consumable dyes and permanent dye unlocks.)

Wildstar: Click armor slot, select appearance, apply. Pages are a bit annoying, but an addon fixes it to display everything in one scrollable window. Searchable database. Can save multiple outfits you swap at will. Dye interface not shown, but all dyes are permanent unlocks and you select your color from a list for each dye channel (you can check multiple dye channels at once to dye them the same color).

Guild Wars 2: Click armor slot, select appearance, apply (consumes a transmute charge - I don't like this part about GW2's system, but the focus here is the UI). One fault is that it only uses icons to identify different appearances - would be better with 3D models. But still not bad and clear in function. Searchable. Dye interface not shown, but uses permanent unlockable dyes and a similar interface.

World of Warcraft: Two variations in the UI, depending on whether or not you're at the Transmogrification vendor (you must visit this vendor to apply a new appearance). You can create new appearances anywhere via the Preview window (saves as a set with a custom name, as seen in top image). It also tracks armor sets and tells you where to obtain set pieces you don't have.

Several months back, I whipped up this thing in photoshop. It's not perfect, but it's just a basic example of what a simple wardrobe UI might look like in FFXIV:

The current Glamour system is convoluted, overly-burdensome on inventory, highly restrictive in terms of use, and lacks a lot of the convenience of other systems.
