Try to stay sensible, practical, and civil.
I'll start off (my knowledge may be a little outdated as I've only played the offline versions):
D'ni-ish pants. Nothing really fits with the Kahlo Pub Jacket.
A business suit or tuxedo, for formal walks through Ae'gura.
[might have copyright issues] Exile and EoA shirts
A sombrero, cowboy, or Canadian Mountie type hat.
A bracelet or watch.
[something I want for David's Journey (as a reward piece of clothing, of course) and am not sure if I want to announce it - PM me if you think you can make it (it would be more complex than just a new shirt logo, about the difficulty of the watch)]
Kim-Jon Il glasses
... that's all I can think of now
