The Duchess of Cambridge is keeping her work-from-home wardrobe prim and pared down.

For a recorded video PSA for the U.K. campaign Time to Change, she wore a chic black turtleneck and mini gold hoop earrings as she voiced the importance of speaking out about mental health. Her husband, Prince William, sat beside her for the appearance, wearing a blue knit sweater layered over a light button-down. The royal couple appeared to be speaking from their country home, Anmer Hall, where they've been spending most of the pandemic. Viewers can catch a glimpse of a sweet photo of the duchess and her youngest son, Prince Louis, in the background.

Both the Duke and Duchess of Cambridge shared a few words about working to end the stigma surrounding mental health in our communities and worldwide. "Movements like Time to Change have helped to transform attitudes and encouraged more openness about mental health in schools, communities and the workplace," said Kate in the clip.

"Over the past 15 years, Time for Change champions have inspired and supported thousands of people across the country," added William. "Mental health has now at last moved into the mainstream as part of our daily lives.

The duchess helped conclude their joint PSA by explaining that caring for our daily emotional wellbeing is just as important as tending to our physical health. "However the work isn't done yet, and we cannot afford to stop here," continued Kate. "It's so important that we value our mental health just as much as we value our physical health."
