What are some fun and easy ideas you guys are planning or think would be cool for LoL-themed halloween costumes?

My fiance wants to be Annie while I dress up as Tibbers. Any other duo-ideas like this that you guys have in mind? Easyness is a big factor for me, because I don't have the time or means to go all out on a replica costume. I figure a bear suit can be obtained easily and Annie is just a trip to the Salvation Army / Good Will stores.

Another fun one would be mobster Graves and Miss Fortune (one of her skins is 20's kind of style I think). This is a bit more elaborate though.
