Oprah Winfrey, Chris Pine and More at the Brunello Cucinelli Dinner in Los Angeles [PHOTOS]

The Brunello Cucinelli Dinner held in Los Angeles on Dec. 5 was truly a star-studded affair, with Oprah Winfrey, Ava DuVernay, Chris Pine, Kevin Costner and more notable names making an appearance at Chateau Marmont for the occasion. Winfrey is a longtime fan of Cucinelli, stepping out for this event in a striking ensemble consisting of a tassle-adorned skirt and tie set off by a cream-colored blazer and dark pointed boots. She is also a fan of sneakers from the brand, having just recently shared photos of herself on social media wearing a multi-colored neutral pair of lace-up low top sneakers.

Also at the dinner was Ruth Negga, who looked chic in a pair of strappy black heeled sandals and a feathery light gray shift dress. Sharp formal looks could be seen throughout the night, with plenty of blazers accenting a range of footwear. See looks from the dinner below.
