Kim Kardashian, Katy Perry and Lindsay Lohan in Their Fashion Week Best

Hollywood met fashion in force at a gala and auction on Monday night in Midtown Manhattan, where Kim Kardashian bid on Balenciaga couture, a nude photograph of Madonna sold for $70,000, and “How do you know Jeff and Lauren?” (Bezos and Sanchez) was a common refrain over cocktails.

At one of the starriest gatherings during New York Fashion Week a crowd turned out for the annual Caring for Women Dinner hosted by the Kering Foundation, to benefit organizations working to end gender-based violence.

Held at The Pool, a restaurant in the Seagram Building, the night was hosted by Salma Hayek Pinault, a Kering Foundation board member, and her husband, François-Henri Pinault, the chairman and chief executive of Kering, which owns Gucci, Balenciaga and Yves Saint Laurent among others. (Artémis, Mr. Pinault’s family investment company, last year bought a majority stake in one of Hollywood’s biggest talent agencies, Creative Artists Agency.)

The philanthropic couple can draw a crowd. Matthew McConaughey, Donatella Versace, Priyanka Chopra Jonas, Naomi Watts, Leonardo DiCaprio and Julianne Moore were just some of the high-wattage attendees on the guest list.
