Jennifer Lawrence is on one stylish streak! Following her pretty pale blue quilted Dior number (with sweet free-falling florals) at the world premiere of The Hunger Games: Mockingjay Part 1 , the blonde bombshell struck again at the Los Angeles premiere last night with another jaw-dropping look.

Channeling Marie Antoinette, Lawrence whittled herself an exaggerated hourglass figure with a stunning silver jacquard silk pannier-style Dior Haute Couture tea-length dress that she styled with a rose gold Roger Vivier clutch, a selection of jewelry (including Vita Fede ear jackets, a Repossi ear cuff, and an Anita Ko ring), and gold Aquazzura sandals. The final look? Royal perfection.

For the after-party, the star did a complete 180 and tapped her dark side, partying it up in a sexy black cut-out chiffon Altuzarra design with pearl embroidery and sheer panels. The finishing touches—a smart Altuzarra tuxedo blazer and a metallic beaded Roger Vivier clutch (below). The verdict here: Another style win for JLaw!
