She re-wore her favourite Zara blazer for an interactive Q&A celebrating her '5 Big Questions on the Under Fives' survey on Saturday.

WATCH: Kate Middleton re-wears her favourite Zara blazer
The 38-year-old royal, who raises Prince George, Princess Charlotte and Prince Louis with husband Prince William, has been highlighting the crucial role early years play in raising the next generation of adults and shaping society.
After unveiling five different looks in the past 36 hours, Kate opted for to re-wear her favourite blazer again, cementing it as one of her fashion staples. She had worn it earlier with a black top underneath, but this time she went for an all-white pairing. The thin jumper underneath featured a boat neckline and ribbed detailing.
The blazer was worn during her 2016 Canada tour, and again at the Docklands Sailing and Watersports Centre in 2017.

The insight Kate was able to give during the appearance was that: "40% of parents feel that community support has grown. However, parents in the most deprived areas are less likely to have experienced this increased support (33%) than elsewhere."

It's been a busy week for Kate, who saw the findings from her big '5 Big Questions on the Under Fives' survey published on Friday.
The palace shared five videos on social media to highlight each of the five key points from the landmark research.
The mother-of-three not only impressed royal fans with her speech – but with her seriously stylish fashion choices.
Kate rewore this Reiss dress from 2012
The first video saw Catherine wearing a stunning blue Reiss button-up dress. The garment has a very sentimental story behind it, since it's the outfit she wore to give her first-ever royal speech back in 2012, when she attended the opening of The Treehouse, a hospice service for Suffolk and Essex.
In further pictures released by the palace, the Duchess appears to have recycled another piece from her early royal wardrobe - this time her white Zara blazer worn during her 2016 Canada tour, and again at the Docklands Sailing and Watersports Centre in 2017.
Another popular look was this bargain Gap jumper
Kate shared a new short video on Friday morning, too, in which she wore a bargain £39.95 red cable knit jumper from Gap, as she pinned another insight from the survey to a brick wall.
A third video showed the Duchess, wearing a repeat polka dot blouse from Equipment, writing down the third key insight: "70% of parents feel judged by others and among these parents, nearly half feel this negatively impacts their mental health."
