TLDR, but I would really love a wardrobe system, similar to Guild Wars 2. Basically, the glamourable items can be converted to glamour-only. You lose the item after sadly, but the look is permanently stored in your wardrobe. From that wardrobe, you can mix and match your clothes, even see how different pieces look together in different dyes (which is unlike 14's current dyeing system). The prisms can be carried in this wardrobe too, so that could free up retainer space. And it can be accessed anywhere.
