After the Phoebe Philo-filled start to her Die My Love press tour, one could only wonder what else Jennifer Lawrence had in store.

Whether she’s running errands in New York or walking the red carpet, Lawrence’s style is defined by an elevated simplicity; a fan of brands like The Row and Hermès, the actor is a stealth-wealth devotee. That’s not to say, however, that her looks lack visual intrigue. Today, Lawrence stuck to her sartorial guns at the BFI London Film Festival, where she offered a lesson in dressing up a little black dress.

The actor arrived at the festival’s gala, honoring Die My Love, dressed in a sleek black halter dress, its plunging V-neck empire bodice made of velvet. Lawrence and stylist Jamie Mizrahi paired the sexy flared silhouette with a strappy black sandal, and—to protect her from the chillier British temperatures—a black coat with shearling trim and floral embroidery, which Lawrence wore draped around her arms.

But it was her jewelry that elevated the look from sophisticated to show-stopping: Lawrence wore a gold torque necklace by Glenn Spiro from his Materials of the Old World collection. Dangling from the hammered gold collar was a sculptural pendant made of seven brilliant cut diamonds flanked by round gold beads, and capped off with an oblong gold bauble.

In her eye-catching necklace, Jennifer Lawrence has found the megawatt jewelry to match her star power.
