This Sunday, the royal family stepped out for this year's Remembrance Sunday ceremony to honor the nation's fallen heroes at the Cenotaph in central London.

According to the Daily Mail, a two-minute silence took place at 11 a.m. and wreaths were laid at the foot of the Whitehall memorial. The Duke of Cambridge and Prince Harry laid their wreaths at the same time, and the website reports that Prince Harry's involvement at the ceremony marked his official transition into a full-time royal.

Meanwhile, the Duchess of Cambridge watched the ceremony from the balcony of the foreign office with the Countess of Wessex and Sir Timothy Lawrence. They were joined by Queen Maxima of the Netherlands, who watched her husband King Willem-Alexander lay a wreath. According to the HRH Duchess Kate blog, the King laid a wreath following an invitation from the Queen to mark the 70th anniversary of the liberation of the Netherlands after the second world war.

The 33-year-old Duchess wore a black double-breasted felt and velvet coat by Alexander McQueen and a mesh birdcage veil. She also had three red felt poppies on the lapel of her coat to honor veterans and their fallen comrades. This is the fifth consecutive year that the Duchess has attended the ceremony at Cenotaph as a member of the royal family.

A day before the ceremony, the Duke and Duchess of Cambridge joined other royal family members at the Royal Albert Hall for the Annual Festival of Remembrance. The Duchess wore a Dolce & Gabbana black lace dress with black pumps, while the Duke wore a navy suit, a navy and red tie, and eyeglasses.

Over the past couple of weeks, the Duke and Duchess have been seen several times while out on official engagements. The royals recently made an appearance at the red carpert premiere of "Spectre," and it was reported that they will be speaking with social media and technology companies—including Twitter and Facebook—sometime this year to talk about protecting young people online from cyberbullying.
