A version of Katniss's wedding gown can be seen here: []
"He unzips the bag, revealing one of the wedding dresses I wore for the photo shoot. Heavy white silk wiht a low neckline and tight waist and sleeves that fall from my wrists to the floor. And pearls. Everywhere pearls. Stitched into the dress and in ropes at my throat and forming the crown for my veil." ~Catching Fire Suzanne Collins
"I don't have to look at Cinna for a signal. I know this is the right time. I begin to twirl slowly, raising the sleeves of my heavy gown above my head.
When I hear the screams of the crowd, I think it's because I must look stunning. Then I notice something is rising up around me. Smoke. From fire. Not the flickery stuff I wore last year in the chariot, but something much more real that devours my dress. I begin to panic as the smoke thickens. Charred bits of black silk swirl into the air, and pearls clatter to the stage. Somehow I'm afraid to stop because my flesh doesn't seem to be burning and I know Cinna must be behind whatever is happening. So I keep spinning and spinning. For a split second I'm gasping, completely engulfed in the strange flames. Then all at once, the fire is gone. I slowly come to a stop wondering if I'm naked and why Cinna has arranged to burn away my wedding dress.
But I'm not naked. I'm in a dress of the exact design of my wedding dress, only it's the color of coal and made of tiny feathers. Wonderingly, I lift my long, flowing sleeves into the air, and that's when I see myself on the television screen. Clothed in black, except for the white patches on my sleeves. Or should I say my wings.
Because Cinna has turned me into a mockingjay." ~Catching Fire Suzanne Collins
