In an unexpected appearance, Kate joined William and Harry for a special outing at Paddington Station. Kate, who is still suffering from morning sickness, was not previously announced to be attending but it appears the Duchess was well enough to step out.
The royal trio meet children from the charities they support on board the vintage Belmond British Pullman train.
The event was hosted by STUDIOCANAL with support from the BAFTA Kids programme, and before embarking the royals met the cast and crew from the forthcoming film Paddington 2.
The Duchess was excited to meet Paddington Bear and she had her dancing shoes ready for an impromptu twirl with the famed storybook character.
Kate wore a pretty Orla Kiely Raised Flower Dress in Tea Rose (£139).
The dress by the Irish designer is part of the label's Autumn/Winter 2013 collection and is no longer available. It features an embossed floral appliqués, with black velvet piping around the neck and waistline.
The dress comes with a detachable bow belt.
The Duchess coordinated the two-tone dress with her simple black Mulberry 'Bayswater' suede clutch, and a new pair of black pointed-toe, block high-heels.
@Giulia_lelepug identified Kate's new shoes as the Tod's Suede Pumps (£335). Masterly crafted by skilled artisans in Italy, the pumps sit atop a sturdy block heel and arch to a streamlined pointed toe. The sole features the label's signature pebbled traction grip.
She kept her jewellery to a bare minimum, choosing her Kiki Morganite Cushion Drop & Diamond Earrings and trusty Cartier Ballon Bleu Watch.
