The “Fine Line” singer, 26, added a special-edition T-shirt to his official merchandise shop, and it features a heartfelt message for first responders.

On the front, the tee reads, “Stay Home. Stay Safe. Protect Each Other.” The back says, “This T-Shirt Fights COVID-19,” and references one of Styles’ song lyrics and mottos: “Treat People With Kindness.”

The white shirt with black font is on sale for $26, with 100 percent of proceeds donated to the COVID-19 Solidarity Response Fund for the World Health Organization, powered by the UN Foundation.

Styles postponed his upcoming “Love on Tour” dates, and recently revealed that he is stranded in Los Angeles and missing his family.

“I think, honestly, it’s obviously disappointing, but it’s not even close to being the most important thing right now,” Styles said after announcing his concert postponement. “I think everybody understands — it’s not like there’s anything you can do about it. I think the most important thing right now is to keep everybody safe.”

Other celebrities who have donated a portion of their own merch proceeds or created a special design for disease relief include Selena Gomez, Rita Ora, Kim Kardashian, Victoria Beckham, Kylie Jenner and more.
