Avaline, the organic wine brand founded by Cameron Diaz and Katherine Power, celebrated the launch of the label’s limited-edition bottle of French Rosé in collaboration with designer Stella McCartney with a star-studded cocktail event in the Hamptons, New York.
The event was hosted by Diaz, Power and eponymous designer Stella McCartney. The evening featured Avaline’s full line of vegan-friendly wines, including Sparkling, Sauvignon Blanc, Pinot Noir and a specialty cocktail crafted with Avaline Rosé.
Both Diaz and Power sported custom looks courtesy of Stella McCartney. Diaz wore a spring 2026 double-breasted boyfriend jacket and wide-leg trousers, embroidered with British wildflowers. Power opted for an oversized dove-print silk set from the summer 2025 collection.
