Cue hyperventilating and squeals of joy: the latest H&M high fashion collab has been annouced, and it’s a doozy. Lanvin will be partnering with the chain to create a collection of both womens and menswear (and we’re betting we’ll want to mix and match both.) The collection will be revealed on November 20th, and Alber Elbaz describes the collection as translating the Lanvin dream for a larger audience. “I loved the idea that H&M was going luxury,” he says. “I thought it was a smart concept, so I say, ‘I do.'”
