Kate Middleton and Prince William still had their island tans when they participated in their annual St. Patrick's Day tradition of visiting the Irish Guards in Aldershot, England, on Monday. This is the Duchess of Cambridge's third time taking part in the festivities, but she changed things up a bit this time around by ditching her usual green Emilia Wickstead coat (which she had worn two years in a row ) for a festive Hobbs coat and matching Gina Foster hat. She also kept with her new "princess" makeover by accessorizing with a Cartier  shamrock brooch which was first worn by Queen Alexandra, the consort of King Edward VII. The duke and duchess pinned shamrocks onto the guards, including their Irish wolfhound mascot, Domhnall, who got a bonus pat on the head from Kate.
Kate and William are fresh off their parents-only vacation to the Maldives . Their trip was met with a bit of controversy, as some felt that it was inappropriate for them to leave their 8-month-old son, Prince George, at home, despite the fact that he was staying with Kate's parents. However, George has been getting lots of travel time with his mom, and she took him on a Middleton family vacation  to their favorite relaxation spot, Mustique, in early February. At the time, Prince William stayed behind in London as he was in the middle of his 10-week agriculture course at Cambridge University.
