Kate Middleton Wore a Black Turtleneck in Her Latest Video Call

After a white coat in Westminster Abbey and a coordinated his-and-hers look with Prince William following Meghan Markle and Prince Harry's Orpah interview, Kate Middleton wore a no-nonsense black turtleneck for a call with Time to Change, an organization in the U.K. working to remove the negative stigma that sometimes comes with seeking help for mental health.

People reports that Kate and William participated in a call with Time to Change to thank everyone involved with the charity. For the appearance, Kate wore a black turtleneck sweater and kept her hair in her usual long, soft waves. William wore a cornflower blue sweater over a collared shirt.

"We wanted to say a big thank you to everyone who has shared their experiences and taken action through Time to Change, helping to challenge the stigma which surrounds mental health," William said.

"Movements like Time to Change have helped to transform attitudes and encouraged more openness about mental health in schools, communities and the workplace," Kate added.

While Kate and William were appreciative of Time for Change's continued work, Kate added that there's still more to do, saying the "work isn't done yet."

"We need to keep talking, keep taking action and continue to stand up to the stigma," William said. Time to Change's funding ends on March 31, so the Cambridge's message comes just in time for the organization's impending closure.

People also notes that Kate and William's message comes after Prince Harry's announcement that he'd be joining coaching and mental health company BetterUp.

"I intend to help create impact in people's lives," Harry said in a statement. "Proactive coaching provides endless possibilities for personal development, increased awareness, and an all-round better life."
