The Princess of Wales showed off her high street earrings as she listened to children open up about their mental health.
Kate praised an "inspirational" new "anxiety toolkit" developed by a leading mental health charity after it collaborated with schoolchildren during an outing in London today.
She visited the Anna Freud Centre to learn about the project, launched on Thursday by the research and development organisation, and meet some of the children who helped develop the initiative.
For the outing, Kate wore a green "wiggle" dress by Suzannah as well as Alessandra Rich heels along with £11 earrings from Accessorize.
As she went on a brief walkabout after leaving the institution, she met a group of children and their parents outside and told them: "I'm leaving feeling inspired – I've learned lots from young people."
The princess had earlier sat down with pupils from St Richard's Catholic College, Bexhill on Sea, and was shown a range of activity cards that provide practical advice to youngsters who may be affected by issues like anxiety.
The children helped to develop Anna Freud's "let's talk about anxiety" new animation and teacher toolkit, which typifies the charity’s vision to empower young people with the knowledge, confidence and skills to manage their mental wellbeing.
When one of the pupils mentioned her interest in sport, Kate replied: "So much in sport is mental as well as the physical skills and abilities, to have these sort of skills and these sorts of things in your toolbox will really help you, probably not just in school but home life and school life and other things as well.”
Kate also joined a series of round table discussions with health professionals and academics from Anna Freud, which Kate supports as patron, and those from the wider community with experience of mental health.
It's Kate second outing this week to mark Mental Health Awareness Week as on Tuesday, she visited the Dame Kelly Holmes Trust in Bath.
There she was joined by the double Olympic champion as well as Love Island star-turned-documentary-maker and advocate Zara McDermott- who is an ambassador for the princesses' Shaping Us early years campaign.
Kate spent time with students from St Katherine's School, from nearby Bristol, who are taking part in the On Track To Achieve programme, delivered by their athlete mentor, Paralympic gold medallist Liz Johnson.
When the Princess sat down for a private chat with the girls, she opened up the floor to questions about herself after listening to their experiences about home and school life.
Afterwards, Dame Kelly said when the schoolgirls quizzed Kate about being a "royal", the Princess said it was something "she had to learn".
Speaking for herself, Dame Kelly said: "A struggle to kind of know that you can be accepted and fit in, and still learning every day."
The double Olympic champion said public speaking was not a "natural thing" to many people and, commenting on Kate, added, "she said she's still working that out".
It came after Kate also admitted becoming a member of the royal family was something she never expected – but then she met and "fell in love" with Prince William.
