Anne's white beaded dress she could barely breathe in was Givenchy Haute Couture by Richard Tissci. It's okay, though, she was into another look in no time....
Hathaway crossdressed like a pro, looking MAJOR in this Lanvin tuxedo and sparkly Brian Atwood shoes that were custom made for her.
The red beaded number Anne looked so effortless in was Atelier Versace from Spring 2011.
Anne's look would not have been complete without a show-stopping gown like this gray version by Vivienne Westwood.
In true Rachel Zoe form, Anne was a seriously 70s disco queen in Oscar de la Renta's gold fringe dress.
Anne's blue dress looked almost liquid--it was Armani Prive Spring 2011.
Lastly, Hathaway wowed in a Tom Ford lace and crystal gown. Pure magic.
