Jennifer Lawrence dazzles at the Mockingjay after-party. A vision of elegance, she kicks off the festivities, setting the stage for an unforgettable evening

Jennifer Lawrence continued what appeared to be a recurring theme on Monday evening as she marked her arrival at the official after-party for latest film Hunger Games: Mockingjay Part 1.

The American actress led the way for the second time that night after joining her cast-mates at the Los Angeles bash shortly after the city’s Nokia Theatre played host to its LA premiere.

Jennifer, 24, opted to switch the Dior Couture gown that dominated the red carpet for a comparatively subdued black evening dress, distinctive by virtue of its halterneck detail.

The breezy gown was teamed with a matching tuxedo jacket, while a glittering clutch gave the overall look an added touch of elegance.

Jennifer was joined at the after-party by a host of stars from the new film – amongst them Jena Malone, whose blood red evening dress, complete with thigh-high slash, ensured she was not overshadowed.

Natalie Dormer proved to be another fashion highlight after changing her sweeping lemon yellow gown for a sleeveless little black dress with sheer chest panel.

For the premiere downtown Los Angeles’s Nokia Theatre LA Live was transformed into Panem’s Capitol.

Instead of a red carpet, there was shiny white flooring and Peacekeepers patrolling across it, while Katniss’s Mockingjay pin was dotted around the place and fiery torches added even more drama.

Another actress catching the eye was Julianne Moore – who looked positively vibrant in contrast to her ashen character, Alma Coin.
