It was a party 10 years in the making. Commemorating a decade-long partnership with Jennifer Meyer, Barneys New York celebrated the launch of Barneys New York XO Jennifer Meyer, the jewelry designer’s first exclusive ready-to-wear capsule collection, with a star-studded private dinner in Los Angeles on November 18.

Our co-hosts for the evening were Meyer’s husband Tobey Maguire and friend Jennifer Aniston, and they welcomed glamorous guests—including Gwen Stefani, Blake Shelton, Katy Perry, Nicole Richie, Dakota Johnson, January Jones, and Rachel Zoe—to toast the jewelry designer’s crossover into clothing.

The 12-piece women’s collection for Fall 2015 embodies the same enduring versatility of the brand’s accessories. Meyer’s signature approach—well-made feminine charms to live in—carries over to her debut line of wardrobe essentials with a unique twist. A distressed denim jacket or classic cardigan to wear with everything, a Breton-inspired striped T-shirt, or the perfect silk belted shift dress showcase the designer’s penchant for polished nuances.
