Kate, 33, looked beautiful while spending the morning at Norfolk Showgrounds to launch a £10 million charity appeal for East Anglia's Children's Hospices.
We do wonder though, is she not FREEZING?!
No coat. Bare legs. Brave Kate!
Kate is four months pregnant with her second child but there was barely a hint of baby bump in her fitted Catherine Walker frock.
Unusually for her, she kept her brunette locks tied back rather than in loose waves and we have to say, we LOVE this look on her!
Kate has been a patron of East Anglia Children's Hospices since January 2012, and last year she recorded her first ever video message in aid of Children's Hospice Week.
Today, she helped launch a new fundraising appeal that aims to build a brand new children's hospice in Norfolk.
Graham Butland, the chief exec of East Anglia Children's Hospices, said: "The Duchess's support continues to help us increase awareness and understanding of the care and support we provide, and in this instance, to highlight the need for a new children's hospice in the heart of Norfolk."
"We'd like to thank everyone involved in the project so far. We're over the first hurdle in gaining planning permission, but we've now got the challenge of encouraging the good people of Norfolk and beyond to help us raise the funds needed to build and equip the new hospice."
Kate has slowly been entering back into the public eye and resuming engagements following severe sickness at the beginning of her second pregnancy.
The royal was diagnosed with hyperemesis gravidarum, as she suffered when pregnant with Prince George, now one. It meant she was forced to cancel several engagements at the end of the summer while recovering.
Next month, she will travel to the US with husband Prince William for two days of engagements in New York. William, 32, will also spend a day travelling to Washington DC.
