A non-stop promotional tour means plenty of impeccable sartorial displays from Jennifer Lawrence.

Stepping out for the Hunger Games book launch cocktail reception in London on Friday night, the stunner lead the cast of Mockingjay – Part 2 with all of her trademark the glamour once again.

Jennifer, 25, put on a racy display in a chic sheer dress that flashed her bra and matching skirt beneath as she made strides from the venue in the company of her co-stars.

Jennifer looked sophisticated with her hair twisted into a low chignon as she opted for a more minimal make-up look than her recent red carpet displays.

While her dress was decorated with bold blooms, she steered away from colour unlike her maroon gown on Wednesday and her decorated dress on Thursday.

Similarly, the star chose to flaunt her sex appeal in a more subtle way, diverting from sideboob and a plunging neckline to hinting at her physique in sheer lace.

The leading lady, who reprises her role as Katniss Everdeen in the hit franchise for a fourth time, was accompanied by co-stars Liam Hemsworth and Natalie Dormer.

Following a full day of promotion, and with many visits ahead on their press tour, the film friends seemed all-too happy to spend more time together.

Natalie kept her slender shape concealed in a long ladylike overcoat but plumped for the same bra-flashing sartorial display as Jennifer in an Emilio de la Morena dress.
