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

Quite frankly, I was never enamored of the WoW transmog system. For one thing, it was limited to one class. It was easy to create the list of quest gear, since you only ever got one piece for your class. Same quest, different gear depending on your class. Would you stand for a glamour system that only counted for your starting class and ignored everything else? Because that's what ESO and WoW and GW2 end up doing.

WoW limits it to one class/armor type because of arbitrary reasons. When you open the transmog log it will know what you how for all armor types and classes but only list those you are permitted to wear. GW2 has a restriction on armor types because the fail-state for their conflicting seams is to render simply... nothing, something that can result in invisible limbs.

And in FFXIV most gear comes in set so you could pretty much compress the unlocks needed from from the 10k armor pieces by at least 5, so down to 2000bits. Go even more extreme and you can cram them down into tiers with the 7 armor types (tank, meleex3, ranged, caster, healer) and leave us at about 300bit for armor which is... Nothing, and way less than the amount of data they needed for expanding our inventory or even the glamour dresser since those need to account for an armor/item id with a bitwidth of at least 16 if not 32 (currently 34227 obtainable items in the game)

Gear does not "come in sets", it comes as individual pieces, like most every MMO in existence. You can have a body piece but be missing every other piece of instance gear for your job. A 64k bitmap (because you always need to leave room for expansion) would be fine, if the gear system used bitmaps. But it doesn't. It uses gear slots, complete with information about 'glamour' and dyes. It uses a set of small tables for the glamour plates. SE may well decide to replace this system with a transmog system like WoW, but ...

Have you looked at the cost of transmog in WoW? You don't need to purchase glamour prisms, true, but every time you switch out one bit of gear for another, it costs you gold. I was greatly interested in reading that the cost for a full gear set for a monk could cost 400 gold (based on some valuation of the gear set in gold), and a visit to one of the vendors who you have to go to in order to get changed out.

Personally, I wouldn't want to do more than expand a glamour prism when-and-where I decided to apply a glamour. Can you imagine the outcry if you had to visit a major city any time you desired to glamour a piece of gear? (I can, because that was the fate of glamour plates until 6.0 came out).

I very well know that armors come in individual pieces. What i meant is that they are relatively easy to put into collections, both by role and by tier. This game also has achievements which you can only get by presenting items to an npc, and achievements can generate items both through the achievement tab and the calamity salvager, so they already got systems in place that can be patched together to produce some kind of glamour log.
