Selina is never referred to as being Catwoman. We don't know why she has to wear that skin tight black costume or the domino mask to be a thief? What do the goggles do?
Don't get me wrong I loved Hathaway's look, but she is about the only character that isn't given any kind of validation for her comic booky elements like the others were.
It's a basic spy/thief outfit. The cat ears are an 'incidental' nod. They never call her Catwoman because they never intended her to literally be a cat-based character.
