Kate on Thursday met senior government ministers at the Royal Institution in London to discuss the importance of early childhood development two days after the Duke and Duchess of Cambridge visited a memorial for the fifth anniversary of the Grenfell Tower tragedy.
Kate, 40, was in high spirits as she met with health secretary Sajid Javid, families minister Will Quince, representatives from the early years sector, and officials from the Department for Education and the Department of Health and Social Care.
The roundtable discussion, hosted by the duchess, focussed on the links between mental health and early childhood development as well as forthcoming research led by the Royal Foundation Centre for Early Childhood.
The roundtable also discussed new findings by the Royal Foundation Centre that show 91% of people agree that early years are important to shaping a child's life.
Kate wore a pale pink tailored suit for the important occasion, which she paired with a smart white T-shirt vest beneath and coordinating high heel court shoes.
The duchess was the picture of sophistication as she met with ministers in the £2,000 Alexander McQueen suit, the same famous fashion house that created her iconic 2011 wedding dress.
Kate finished her look with a dazzling jewellery set, opting for her pair of £3,750 Mappin & Webb 'Empress' diamond carriage earrings and her matching £2,000 Empress mini white gold and diamond pendant necklace.
Her single additional accessory showing she really meant business was a leather zip-around document case.
The mother-of-three’s brunette locks were swept back and styled in her signature blowdry, and she wore simple make-up – pairing subtle smokey brown eye with nude pink lipstick.
The research centre was set up by the duchess in 2021 after working with academics and professionals in the field who believe what happens to the youngest members of society has a direct affect on their lives as adults, including their mental health, addiction and social exclusion, as well as their physical wellbeing.
Speaking ahead of the meeting, Kate said: “Our experiences in early childhood fundamentally impact our whole life and set the foundation for how we go on to thrive as individuals, with one another, as a community and as a society.
“The findings published today present us with a huge opportunity and demonstrate there is real appetite from the public to bring this issue up all of our agendas.
“There is more we can all do - every member of society can play a key role, whether that is directly with a child or by investing in the adults around them - the parents, the carers, the early years workforce and more.”
