According to WWD, the range will include the Paris-based designer's first-ever menswear and children's looks: for guys, twenty items of clothing and five accessories; for kids, thirty garments and ten accessories (fingers crossed the latter includes Marant's take on a binky).
"I was very proud that H&M approached me to do this collaboration," Marant says in the teaser video below.
"I really tried to do the essence of my style, and my style is about combining the essence of my different ideas. The collection for H&M is about the ideal wardrobe, which you can do a lot with."
The collection will be available at H&M stores on November 14.
