Trish Summerville, the costume designer for “The Hunger Games: Catching Fire” has confirmed via The Hollywood Reporter that the dress worn by Jennifer Lawrence on her Katniss Capitol Couture is indeed her wedding dress. I guess this will be the one she will wear during her interview with Caesar Flickerman.

“Katniss’ white gown is by a designer named Tex Saverio in Jakarta. He is amazing!  I found his designs quite some time ago and saved his information for a perfectly fitting project, then came Catching Fire – perfect!” she said.

“We did several Skype calls with sketches to work together in designing the wedding dress. I had seen a dress he designed with a similar metal bodice, and I wanted to incorporate it into our wedding-dress design,” Summerville adds.

She also pointed out the bodice, a Swarovski-crystal-clad “organza corset under a metal cage.” The metal pieces rising up are meant to signify fire and flames, while layers of laser-cut feathers at the waist and shoulder tie in the film’s “Mockingjay” concept.
 
The skirt also has numerous layers of organza and chiffon ruffles giving it grandness but still making it seem airy and fluid for movement. As Summerville explains, “This is very important for the twirling/ spinning  Katniss does onstage, per Caesar Flickerman’s request.”

On Effie’s dress:

Summerville confirms that Effie Trinket’s red ruffled poster dress and matching shoes are indeed from the house of Alexander McQueen, as THR had reported.

On Peeta’s costume and boots:

she also reveals that Peeta’s suit is by a Korean designer that she is “obsessed with” called Juunj. “He is unbelievably talented,” she writes. “And Peeta’s boots are by Rick Owens. “
