The Duchess of Cambridge got all dressed up for a night at the museum. And she looked awesome.
Going for a striking change from the smart short-skirt suits she has been sporting for her latest formal events, she turned up to London's Natural History Museum in a gorgeous flowing cream gown.
The almost futuristic design, with a zipped front and slits, might have looked like a mistake with a paper shredder on some of us, but the Duchess rocked it - of course.
It was a short trip from her Kensington Palace home to the museum, where she joined guests from the arts and culture sector for the Art Fund Museum of the Year Award.
And it was just as well, because those stunning strappy sandals she wore with her mesh-panelled, off-the-shoulder Barbara Casasola dress and sparkly clutch bag would not have been ideal for a long walk.
Kate, who is patron of the Natural History Museum, was there to present the £100,000 award - the world's largest museum prize - given annually to one outstanding museum which has shown exceptional imagination, innovation and achievement.
Artists such as Cornelia Parker and Antony Gormley were also there, along with Grayson Perry, who also stunned in a sequinned purple, yellow and orange dress with flared sleeves. He said it was a design by Claire Cooper, one of his students at Central Saint Martins.
Kate spoke to representatives from the five museums shortlisted for this year's prize, including Jupiter Artland in West Lothian - apparently one of Prince George's favourites.
Its representative, Nicky Wilson, who said she was delighted to meet the Duchess, said: "She said he comes here quite often. He loves the 3D sculptures."
The little boy, who will celebrate his third birthday later this month, has been spotted at the museum previously, admiring the dinosaurs on display.
The other four organisations on the shortlist for 2016 are: Arnolfini, Bristol; Bethlem Museum of the Mind, London; Victoria and Albert Museum (V&A), London; and the York Art Gallery, Yorkshire.
