Anne Hathaway, who is shooting in the movie The Dark Knight Rises as Catwoman, is grateful to Kate Middleton, the Duchess of Cambridge, for she always dressed ladylike and makes her style into fashion trend.

“Can I tell you how grateful I am to Kate Middleton?” she told USA Today. “Because she is such an advocate for dressing like a lady … I’m just very grateful to [her] for making looking appropriate really fun again. So, right now my fashion choices are all about Kate Middleton.”

Hathaway sported her Middleton-inspired style on Friday while promoting her new movie One Day.

However, the outfits are a far cry from the skin-tight costumes of Catwoman in The Dark Knight Rises, which is currently being shot in Pittsburgh. "I had to change my body in order to achieve the shape I wanted for Catwoman," Hathaway said.

"We fit it over the course of a few months, and every time I would target a different body part we could take off the Spanx," she laughed. "So it's not your traditional movie prep."

Hathaway also had to stock up on flats. "There's a reason why she wears heels," Hathaway said, but "doing stunts in heels is a little hard on your feet. Normally I live in high heels (but) I have to wear flats all day and just kind of save up all my high heel time for the catsuit."
