The next big fast-fashion collaboration is here

H&M aims to bring the haute couture of French design house Balmain to the masses with a new collection this fall.

Olivier Rousteing, head designer at Balmain, announced the partnership last night on Twitter, which H&M confirmed.

"I want to talk to my generation: this is my main purpose as a designer. H&M allows me the unique possibility of bringing everyone into the world of Balmain, getting a piece of the dream and creating a global #HMBalmaination: a movement of togetherness, fueled on a hashtag. The collaboration felt extremely natural to me because everybody can connect with the H&M brand. It calls for unity, and I am all for it," said Olivier Rousteing.

H&M says Balmain has always remained true to the vision and spirit of its founder, expressing energy, fun, amusement and freedom, with appeal for everyone. It was a natural decision to highlight the signature Balmain pop charm through collaboration with H&M, the company says.

"We are excited to have Balmain as our guest designer at H&M and create a truly involving experience for everybody. With its mix of couture spirit and street wear attitude, Balmain owns a unique style, at once opulent and direct, sensual and energetic. It is also closely linked to the show business and music worlds, which adds another element of surprise," says Ann-Sofie Johansson, creative adviser at H&M.

The collection will be available Nov. 5, in around 250 stores worldwide and online, the collection will feature clothing and accessories for both women and men.

H&M has around 3,500 stores worldwide.
