The Duchess of Cambridge made her second appearance of the day at the Wildlife Photographer of the Year, today is the first time Kate has been seen since announcing her second pregnancy.
Despite still suffering from the effects of a rare form of morning sickness, the pregnant Duchess greeted photographers at the Natural History Museum.
For the evening event she had changed from her earlier formal outfit by Alexander McQueen into a glamorous gown by Jenny Packham.
The powder blue wrap over dress trailed to the floor and had a short skirt underneath.
Kate is a keen photographer and patron of the Natural History Museum, which is hosting the event it co-owns with BBC Worldwide.
The Duchess was joined by veteran broadcaster and wildlife documentary-maker Sir David Attenborough to present prizes to the winners.
