I keep noticing that my wizard(s) are wearing equipment that is 15, 20 or more levels below their own level. I usually notice this because i start wondering why their mana is going away so fast.
I think it would be real useful to have Eloise (she's the seamstress after all) pop up and say something like "Hello, you wizard. I notice that your wardrobe is badly in need of being updated. ) if you hit 10 or more levels over the level of one or more pieces of your gear.
Course there should also be a way to disable that pop up for those players that happen to want to wear really low level stuff for some reason - so they don't need to be annoyed with it.
