Billie Eilish has ventured into yet another fashion collaboration with fashion brand H&M for a collection aimed at promoting sustainability.

The collection, made entirely from sustainable materials, is made up of items inspired by Eilish’s signature style. The collection includes baggy t-shirts, bucket hats and oversized sweaters, all of which are emblazoned with her logo.

In the past, Eilish has collaborated with other fashion brands such as Bershka, Freak City and Urban Outfitters. She also fronts a merchandise shop online called “Blohsh.”

In recent months, Eilish has become increasingly vocal about sustainability and the fight against climate change. She recently released a PSA video with Woody Harrelson called “Our House Is On Fire,” which details ways people can live more sustainable lifestyles. The video aired on Eilish’s episode of SNL. In the past, she also offered fans free concert tickets in exchange for a promise to help fight climate change.

The H&M collection features a campaign with the work of 3D makeup artist Ines Alpha, who also created an exclusive Snapchat filter for the collection.

Eilish isn’t the first artist to collaborate with H&M for merchandise. Other lines have been released from the likes of Shawn Mendes and Ariana Grande. Eilish is, however, the first celebrity to make her line sustainable.

“We’re super excited about this merch collection drop,” says Emily Bjorkheim, head of design for Divided, H&M. “Billie Eilish is obviously an inspiring artist but also someone a lot of people around the world admire for her personal style and empowering way of expressing her values. We want to enable her fans to step into her world and feel empowered to freely express their style as well.”

The Billie Eilish x H&M collaboration is currently available online and in-store.
