It’s easy to forget that Isaac Mizrahi was once on top of American fashion. Lately, he’s probably recognized more for his sold-out cabaret shows at Café Carlyle or his cameo in Timothée Chalamet’s Marty Supreme than for the technicolored sportswear that made him famous. But this is a designer who came up with Marc Jacobs in the ’90s and whose namesake label was once backed by the Wertheimers. Unzipped, his 1996 doc, is probably as foundational to the hardcore Millennial fashion consciousness as The Devil Wears Prada. When Mizrahi sold his namesake brand—by then a licensing factory owned by Xcel Brands—to WHP Global in 2022 in a deal that valued the brand at $68 million, it was reportedly generating $400 million in retail sales.
