I deleted the Kantai Collection tag as this is not a kanmusu. The single white stripe around the skirt is obviously deliberate and there are only 6 kanmusu who have a sailor uniform with that feature (4 Kagerou class and 2 pre-kai ni Furutaka class) and the character doesn't resemble any of them, either in the character's appearance or in the rest of their clothing. There's nothing to suggest that it is some other kancolle character wearing an unusual outfit, and the kantai collection tag obviously refers to the Shigure picture in the same image set. None of the other 5 pictures in the set have anything to do with KanColle either.
