It's Carolina Herrera's 35th anniversary in the business, and everyone's celebrating. The designer took over West Village haunt Omar's Thursday night to throw a party for the launch of her new anniversary collection, Carolina Herrera: 35 Years of Fashion. The book features vintage images of celebrities (and noted Herrera fans) Bianca Jagger and Andy Warhol, as well as editor Diana Vreeland. But for the launch party, a whole new cadre of It girls and style icons were in attendance: Serena Williams, Karlie Kloss, Olivia Palermo, Miroslava Duma, and Priyanka Chopra, as well as Herrera's own children. Many of them, Chopra included, turned out in their finest Herrera ensembles, but it was Chopra's chill chambray look that commanded the room.

Who: Priyanka Chopra.

When: Thursday, October 13.

Where: The launch party celebrating Carolina Herrera's new retrospective book, Carolina Herrera: 35 Years of Fashion, in New York, New York.

What: A chambray wrap jacket with zipper details and matching slit skirt by Carolina Herrera, pointy-toed black pumps, and a CVC Stones choker.

Why: Since breaking out among American audiences with her starring role in ABC's Quantico, Chopra has quickly become a fashion insider, sitting front row at Altuzarra and Thakoon. (Despite that, she confessed in an interview last month that the glamour of it all doesn't come naturally to her — she's just as happy in a jumpsuit with a minimalist, 10-minute beauty routine.) For a resistant fashion plate, she's taken to it well. For her appearance at Carolina Herrera's anniversary party, she wore an unfussy chambray wrap top and skirt cleverly disguised as a dress. While during the designer's Spring 2017 show, the piece was presented with a white button-down shirt underneath — likely prompting collective ahs from the street set — Chopra opted for the slightly more daring option, and abandoned the shirt. It's like a deconstructed Canadian tuxedo. Paired with a high updo and a dark lip, Chopra took one of Herrera's cute yet conservative designs and gave it a contemporary edge.
