The famous duo stepped out to attend friend and music executive Steve Stoute's wedding in New York on Sunday, where he married longtime girlfriend Lauren Branche—and their coordinating black ensembles were ones for the books. For the occasion, Mrs. West donned a wow-worthy caped Valentino gown, while Mr. West opted for a sharp Haider Ackermann suit. "Last night's vibes- Haider Ackermann x Valentino," Kardashian wrote alongside a photo of her with her husband at the venue (above). She also shared another snap from the day (below) with the caption: "What a beautiful wedding! Last photo before we checked in our phones. [Love] to Mr. & Mrs. Steve Stoute."
