Who: Kristen Stewart

Where: On “The Tonight Show Starring Jimmy Fallon” to promote her new film, “American Ultra.”

When: Tuesday, August 11th

What: A low-cut black DVF romper, Casadei sandals, and a Jacquie Aiche black leather choker.

Why: Stewart offsets the masculinity of her tuxedo-style romper with a sultry smoky eye and a delicate-but-edgy necklace. As they say, it’s all in the details.
