Kate Middleton and her husband Prince William will attend an event run by mental health charity Mind, in collaboration with World Mental Health Day at Harrow College in London on Oct. 10. As part of their official engagement they will meet young people who are engaged with Mind as volunteers.

These volunteers have experienced mental health problems at some stage in their lives. For the royal couple, raising awareness about mental health is a cause that is close to their hearts. This visit comes after Middleton’s solo official engagement to the Anna Freud Centre that she took up; post her maternity leave in September.

The British royals will learn about the new Mindkit project, which is being implemented across London. It educates young people about emotional health and resilience. William and Kate will also be updated about the anti-stigma campaign Time to Change, which aims to break the stigma of speaking about mental health issues.

“We are delighted that the Duke and Duchess of Cambridge will be joining Mind to celebrate this year’s World Mental Health Day,” said Paul Farmer, CEO of Mind.

Earlier, Middleton attended to her royal duties as she paid a private visit to Send Women’s Prison on Friday. She continued her sartorial elegance in a chic and smart ensemble as she visited the prison to see the work carried out by the Rehabilitation of Addicted Prisoners Trust, which works to help prisoners struggling with drugs and alcohol addiction.

For the visit, Middleton wore a tailored grey dress, featuring long sleeves, a V-neckline and a peplum bodice. She paired it with a matching pencil skirt. The stylish winter silver tweed dress is by London-based label The Fold.

The highlight of the Eaton dress silver tweed was a structured silhouette and an extremely flattering peplum detail at the waist. It also had structured panels and an asymmetric waistline. The 33-year-old completed her look with Jimmy Choo heels and a clutch bag in a deeper shade of grey by Hobbs.

The mother of two is a patron of various children’s charities including Place2Be, a charity that provides counselling for students in schools. Earlier this year, she showed her support for Children’s Mental Health Week with a recorded video message.
