The problem is that it's like it's trying to take the more 'realistic' approach that Nolan has while still keeping it Catwoman, which really doesn't work. The Joker and Batman costumes both work because theatrics and image are a major part of their character. She's a catburglar, it makes no sense for her to have a theatric costume like that, especially when it's just a general 'stealthy' suit with some weird goggles.
Granted, it'll really depend on how the character's written and how Hathaway plays her, and things always look different in motion after post-production, but on first glance it just doesn't seem to fit.
