GP’s Amagansett backyard made for a decidedly relaxing makeup studio when her friend, makeup artist Gucci Westman, came over to help her get ready for a screening of the new Netflix series The Politician. The late-afternoon, late-summer light was perfect; there were vodka martinis and Aperol spritzes, dirty jokes, and even a wardrobe malfunction (or two). Westman was the woman behind GP’s look at her wedding, and she’s also the woman behind the brilliant line of glow-inducing, skin-coddling makeup essentials Westman Atelier.
