To our surprise and delight, all three Cambridge children took part in the Trooping the Colour procession for the first time as part of the Queen's Platinum Jubilee celebrations.
But while all three Cambridge children looked wonderful, it's Princess Charlotte's dress you can buy for your own little one's wardrobe.
Accompanied by her mum the Duchess of Cambridge and the Duchess of Cornwall as well as brothers, Princes George, eight, and Louis, four, Charlotte, seven, was looking as beautifully presented as ever in a blue dress with fluted sleeves.
And it looks like the cornflower-blue colour was a deliberate choice — with both her great-grandmother, the Queen, and also the Duchess of Cornwall, looking resplendent in similar shades.
The baby blue dress, £77, is from a Portugal-based children's and accessories brand label called Patachou.
As the Duchess of Cambridge is a fan of rewearing clothes she's had for many years, she's instilling the same eco-friendly values in Charlotte, too. Because this dress is a past-season favourite and is now only available via the Children Salon Outlet.
And, bonus, it has been reduced by 30% from £77 to £54. Lined in 100% cotton with a polyester/chiffon overlay, it is the party dress of dreams with a ruffled hem, those fluted sleeves, and the sweetest bow at the neck.
At the moment it is still available for children and teens aged two-14 years. But given how popular Princess Charlotte's style is, we don't think it'll be around for long.
