For Katie Holmes and her new beau, Jason Bard Yarmosky, opposites evidently attract. The couple made their first official red-carpet appearance over the weekend in ensembles that served contrasting color palettes and equal amounts of stripped-back ease. Attending the 2026 Guild Hall Summer Gala in East Hampton on Friday night, Holmes and Yarmosky—a New York–based fine artist known for his portraiture—were the image of mismatched cohesion. Yarmosky also embraced this effortlessness, wearing an all-black ensemble comprised of trousers and a form-fitting crewneck.
