Prince William looked dapper than ever at today's Order of the Thistle Ceremony in Scotland.
The Duke of Cambridge arrived at the St. Giles' Cathedral in Edenburgh to take part in the Knights of the Thistle service sporting an emerald green robe with a matching hat (take a look at that feather, people!).
William wasn't the only one to wear the ornate ensemble—Queen Elizabeth II, Princess Anne and Prince Philip were also in attendance.
Thursday morning's ceremony honored Glasgow 2014 Commonwealth Games chairman Lord Smith of Kelvin and former Coutts bank chairman the Earl of Home, who were made Knights of Thistle. The title is Scotland's highest national honor.
The award is bestowed on those who have held a position in public office or have made a significant contribution to national life.
The only title higher is the U.K.s Order of the Garter.
William, who currently holds the title of the Earl of Strathearn in Scotland, was installed in the Order of the Thistle back in 2012.
Meanwhile, Anne was invested back in 2001.
Following the big event, the royal family went to Holyrood Palace—the queen's official Scottish residence—for a lunch and reception in the Great Hall.
