Catherine, the Duchess of Cambridge joined Queen Elizabeth II and Prince Philip, the Duke of Edinburgh for an official visit to Baker Street Underground Station to take a ride on the London Tube on March 20, 2013 in London, England.
The six-month pregnant former Kate Middleton was gifted a button that read “Baby on board!” which made her totally crack up with laughter…
Duchess Catherine wore a dark teal above-the-knee dress with a matching coat by Marlene Birger that featured black braiding along the edges, accessorizing with a black pillbox hat, black gloves, tights and pumps as well as her dangling blue sapphire and diamond earrings that match her engagement ring.
Queen Elizabeth II, 86, who got a special tour of the driver’s cabin, looked smart in her cream “summer tweed” dress and coat ensemble by Karl Ludwig, matching cream Angela Kelly hat, accessorizing in black and carrying her ever-present black Launer bag.
The royal trio, who don’t customarily take the London Tube, made the visit to mark 150th anniversary of the London Underground.
Though Duchess Kate said that she had been a regular traveler on the tube until her marriage to Prince William, the future king of the United Kingdom.
Queen has also been on the London Underground prior to the visit as she had first traveled on a tube at age 13 in May of 1939 with her sister, Princess Margaret, and their governess.
London Underground Chief Operating Officer Howard Collins who presented Kate with her “Baby on board!” badge joked “we have been issuing them for the last 10 years and I explained how fantastic they were and how they really do make a difference - saves men the embarrassment of having to guess if a woman is pregnant.”
And of course they can then decide whether it would be chivalrous to hand their seat over to the expecting mother.
