Another peculiarly nonsensical point is made apparent as Barbara introduces herself to Bruce and Dick: why the hell is she still wearing her school uniform? We get it, she came from a boarding school in England, but surely she would've just changed into something else before hopping on a plane and heading to the U.S.? It just doesn't make any sense and it's hard to think of any reason for it beyond indicating to the audience that she's a young, young woman.
