Jennifer Lawrence Doesn't Wear Dior, Which Is A Big Deal

JLaw's back and better than ever!

On Sunday, Jennifer Lawrence and other "Hunger Games" cast-members kicked off the "Mockingjay" promo tour in London at the film's first photocall at the Corinthia Hotel.

For the special occasion, the 24-year-old Oscar winner sported an outfit that for once wasn't a Dior (it's a big deal, guys—Jenn's a Dior spokesperson, after all): a white trouser suit from Public School. The "American Hustle" star paired the slouchy suit with a black cami, silver pumps and a long necklace.

You'd never guess it from her striking appearance but the "Serena" star was battling strep-throat as was co-star Josh Hutcherson, who was too ill to attend the event.

Fortunately, there were plenty of other stylish "Hunger Games" stars, including Elizabeth Banks, Julianne Moore, Donald Sutherland, Liam Hemsworth and Natalie Dormer, who currently covers the December issue of Flare magazine.

On Saturday, Jenn and Liam made a guest appearance on "Wetten, dass..?" in Austria, where she wore a nude bodycon 3.1 Phillip Lim dress that showed off all her curves.

She has flawless style:
