There’s no such thing as too much Kate, which is why we’re pleased to report that the Duchess of Cambridge was up and about once again this morning as she visited Baker Street Station to mark 150 years of the London Underground with Queen Elizabeth and Prince Philip. According to reports, Kate hadn’t been scheduled to appear with the couple but came along anyways. Why? “She just fancied it,” said a senior royal aide. Fancy that.

Much fun ensued during today’s visit, as the royal trio greeted passengers, toured the oldest operational carriage in Britian (a Victorian steam train from 1892) and renamed the S Stock train the Queen Elizabeth II. The Tube staff even presented Kate with a special “Baby on board” pin, which she found pretty funny in this video. (Where can we get one?)

Kate wore a dark teal coat by Danish designer By Malene Birger that looked very similar to this Rebecca Taylor jacket she wore last year. Just different enough, though, to warrant a new piece in the royal wardrobe. To accessorize, Kate wore a black wool fascinator (the same she wore to a wedding in 2011 according to HRH Duchess Kate), a black suede clutch, Cornelia James gloves and black suede heels by Episode. Once again, she wore Diana’s diamond and sapphire earrings, which she’s spotted wearing often.
