That tidbit about the Kimono and no underwear is real. What I didn't say though is that although wearing underwear with kimono is still considered bad manner and frowned upon, its not a grave insult anymore. THAT and that kind of short kimono during old Japan was only worn by prostitutes XD<br/><br/>My logic behind that hole: Suzutsuki was a Japanese Warship of WWI to WWII, some knowledge of Japan customs should be part of her programming as a given. The problem being that her knowledge was kinda... outdated being an old warship, add along that being part of FOG, her knowledge of current Japanese state would be kinda holey at weird places... especially since her best method of finding out would be either experiencing that personally OR through the FOG database about Human custom (which I imagine would have so many holes to make a swiss cheese blush)
