CASADEI’S DEBUT: “I said, ‘You give me a mood, and I will create something that works for both of us,’” Casadei creative director Cesare Casadei told WWD of the brand’s upcoming collaboration with Prabal Gurung that will debut at the designer’s runway show Saturday. This is Casadei’s first partnership with an American-based designer (as well as the creative director’s first New York Fashion Week). The footwear brand worked closely with Gurung to create two silhouettes for his spring collection — both a reinterpretation of Casadei’s Blade wedge. The result: a sleek acetate-and-steel wedge with a degrade effect that comes in white, gray, black or red. A sandal will retail for $1,000 and a mesh pointed-toe style for $900.
