I would actually like this fixed on the developer's end, because I play all three healers regularly and have to use the same glamour on each of them (or use JSE to have two, but that's sort of cheating and relies on liking the JSE and wanting to use that as a glamour set). It would be wonderful to have three completely different ones and it would mean carrying less random items of clothing around with me everywhere for relaxing in, but the game design doesn't make it easy. You may want to dismiss race/sex/class lockouts and other limitations in favour of blaming the players, but there's no denying that these exacerbate the problem greatly. The people crying that (say) female-locked clothing makes people more 'unique' ignore the fact that it lowers the pool of options we all have to choose from to mix and match things which don't look utterly terrible with other pieces we want to base a glamour on.
Furthermore, the storage problem is real. The desire to match things is real (so many great HW dungeon pieces are undyeable and only available in brown, which isn't a colour I like). There's a head piece I have been trying to get (dungeon drop) since I first started the game, and I've still never had it drop and go to me
How do we decide who is allowed to wear the coat and the bustier, anyway? First to glamour it right after patch day gets to rep it? Or is it just completely off limits to everyone to avoid offending the Eorzea fashion police? If someone likes the aesthetic and glamours it to all of their PVE/PVP sets on all jobs that just means the team needs to work on more items with that aesthetic. It's not the player's fault for thinking they look gorgeous in a cool-looking coat.
