Today, Kate joined the Queen and the Duke of Edinburgh at Baker Street Underground to celebrate the 150th anniversary of the transport network.
The royal party met staff and toured the trains before the 86-year-old monarch unveiled a plaque naming a new train the Queen Elizabeth II.
The Duchess of Cambridge was presented with a “Baby on board” badge. This is suppossed to overcome the awkwardness often felt by pregnant women of having to ask someone to give up their seat.
The Duchess accented her look with black accessories. She wore a beret-style hat by Whiteley Fischer (worn in January 2011), her UFO bow clutch, her Cornelia James wool gloves with side bow, opaque tights, her suede Episode ‘Angel’ pumps and her sapphire and diamond drop earrings.
Her hair was styled in loose curls showcasing the textures and tones of her tresses.
