So, I know this has been asked for a couple of times by now but I think it is important to make sure voices are heard that this is a very wanted feature.
I'm fairly new at FFXIV, came over from GW2 and WoW and been having a blast. One thing in particular I absolutely love are the armour sets in this game which are absolutely gorgeous. A problem, however, is how bulky and bothersome it is to collect this armour and use the Glamour system. My retainer have been quickly filling up with armour pieces that I'm very fond of, from multiple classes now especially since I've been working on levelling up a Healer and DPS class as well.
I think the developers really should consider looking at systems like the Wardrobe system of Guild Wars 2:
Which is a fantastically easy system to gather and use different armour pieces for glamour.
