After stealing the show in a gorgeous low-cut Prabal Gurung dress in NYC on Monday, Anne Hathaway has opted for yet another slinky dress at The Dark Knight Rises premiere in London on Wednesday.

Hathaway, 29, hit the red carpet in a dazzling gold Gucci halter gown with plunging armholes that dipped down to the top of her hip, exposing her pin-thin bod. So as not to take away from the number's neckline, adorned with fake flowers and beads, the actress opted for tiny Tiffany & Co. studs and satin Casadei heels.

Before jetting off for her flick's European premiere, the actress, who was dressed in low-key threads that helped her blend in with commuters, packed on some PDA with her fiance, Adam Shulman, during an NYC subway ride on Tuesday.

Prior to her major makeover and slimdown to portray dying prostitute Fantine in Les Miserables, Hathaway was hard at work whittling her waist for The Dark Knight Rises.

"I just started to do Bikram yoga," she told Chelsea Handler in August 2011 during an episode of Chelsea Lately. "And right now, I'm, like, living on kale and dust. "The catsuit's unforgiving, man. It takes three of us [to get me into it]."
