What does "W.C" on Izumi Curtis's slippers mean? What does "W.C" mean? My guess was "water closet" - basically toilet slippers. If my guess is true why does she wear it? Is it a popular thing in Japan or Germany for housewives to go out with toilet slippers?

  W.C. = Water Closet. = toilet.  
  
  In Japan, in Inns and other places like that sometimes they have public bathrooms (toilet) and some of them have slippers to be used inside that bathroom, often with W.C. written like that, and, yes, some of these bathroom slippers are exactly like what Izumi is wearing. (I saw them in some other anime and manga, too, but I got these pics form Google. XDD)
