“Everybody back up!” someone called to a crowd of people surrounding the model and actress Christie Brinkley, who was standing near a neatly trimmed lawn on a sunny and hot Saturday afternoon. Ms. Brinkley had just arrived at Polo Hamptons, an annual cocktail party and polo match held over two weekends in July on the sprawling, private Fishel estate in Bridgehampton, N.Y.
“I’ve always gone to polo throughout my time out here because it is so East Coast,” said Ms. Brinkley, 69, as she sipped from a small bottle of rosé from Bellissima, her wine label, which people were also drinking nearby. “And there are usually some cute polo players.”
The event on Saturday, which drew more than 900 people, was organized by Social Life magazine, a lifestyle publication based in the Hamptons that was celebrating its 20th anniversary. The afternoon attracted a crowd that included Jean Shafiroff, the philanthropist, Lizzie Asher, the president of Macchu Pisco, a spirits company, and Maria and Kenneth Fishel, who own the estate.
As the match began, spectators sat under the crisp white tents lining the field, watching as horses and riders raced past.
Just beyond the seats, there was a row of new BMWs (the carmaker was a sponsor of the event) and a line of cabanas from brands including Oscar de la Renta, Piaget and Permanent Touch Cosmetics, an anti-aging skin spa advertising various treatments.
“When I pulled up, there was a hat that was bigger than the woman that was wearing it,” Ms. Brinkley said. “It is fun to see all the get-ups.”
