Who: Actress Rachel Weisz.

When: Thursday, August 24.

Where: On her way to a taping of The Late Show with Steven Colbert in New York.

What: A black and red Altuzarra dress and metallic heels.

Why: This summer, actress Rachel Weisz stars in "The Lobster," a twisted, dystopian take on the rom-com genre. That daring but refined attitude is apparent in her clothing choices, too. This week, gearing up for the release of her new movie, "Complete Unknown," she appeared on an episode of The Late Show with Steven Colbert in New York, wearing an elegant but playful dress by Altuzarra, its black fabric peeled back to reveal a bright red panel. A design from the label's spring pre-collection, it's a perfect fit for Weiss: as chic as one's come to expect from the actress, but still unexpected.
