The countdown has begun! For the next two weeks, Jennifer Lawrence and the gang will undergo a marathon of photocalls, screenings, and premieres to promote the latest installment of the best-selling quadrilogy (formerly tri-): The Hunger Games: Mockingjay Part 1, slated to hit theaters Nov. 21.

The first on the agenda? Yesterday's photocall in London where Lawrence upped the style quotient in a sleek pantsuit, which not only illustrates how far her style has evolved since the first Hunger Games film, but also sets a high-fashion tone for her next red carpet appearances. For the occasion, she chose incredibly chic white Public School suit separates, adding a sexy spin with a lace-trimmed black top and a contemporary edge with an EF Collection diamond bar lariat necklace and silver mirrored Brian Atwood pumps.

Not too formal, and not too casual. The star struck the right balance with her sophisticated suit—and we're hungry for more. In the meantime, take a trip down memory lane to see how much has her style has changed, from her first photocall to her present.
