Wang made the official announcement at Coachella during the party he co-hosted with H&M. But to make sure everyone knew, the designer also posted the announcement to his Instagram account at midnight on Sunday. Now that it's on Insta, it's the real deal.

"I am honored to be a part of H&M's designer collaborations," Wang said in a statement. "The work with their team is an exciting, fun process. They are very open to push boundaries and to set a platform for creativity."

This is the first time the retail store has collaborated with an American designer (past designers include Karl Lagerfield, Lanvin, and Isabel Marant). Wang is also the youngest designer they've worked with, being only 30.

But before you start lining up at your favorite H&M, this collection won't be hitting the stories until November 26 where it'll be sold at 250 H&M stores worldwide and include both men's and women's clothing as well as accessories.

Take a look at the collection at E! News.
