The corseted strapless gown with lace and chiffon panelling had a revealing barely there lower half which drew gasps from the assembled crowd.
Kristen sported a gorgeous and glossy side swept hair style. She finished off her look in impeccable style with a bold fuchsia lip colour, a gold necklace and her favourite Cartier bracelet for finishing touches.
Joining Kristen on the red carpet were her Twilight co-stars who all put on dazzling displays to show their truly different styles.
Ashley Greene went for a more traditional take on the glamorous nude coloured gown trend. The 25-year-old actress wowed in a custom made Donna Karan dress, Giuseppe Zanotti shoes and Bulgari jewels.
While preparing for the premiere Ashley tweeted to her fans.
"In hair and makeup…. Getting excited to see everyone…. #Twilight #twihards, (sic)" and after getting dressed Ashley added, "On my way to see all the fans! SO excited!! (sic)"
Also keeping with the neutral toned gown trend was actress Nikki Reed who went for a more beige shade of dress with black piping.
Other notable stylish stars at the premiere were fashionista sisters Elle and Dakota Fanning.
Dakota showed off her new brunette hair style at the event, with the 18-year-old stepping out in a gorgeous teal draped georgette dress by Elie Saab from the Haute Couture fall/winter 2012 collection. The gown, which had a slit lace and embroidered sides, was completed by the addition of teal Le Fenice heels.
Equally stylish was Dakota's 14-year-old younger sibling Elle who wore head-to-toe Prada and a pair of kooky platform heels.
