Kate Middleton Attends Order of the Garter 14 Years After Making Debut as Prince William's Girlfriend

Kate Middleton attended one of the oldest royal traditions on Monday: Order of the Garter.

The order of chivalry was founded by King Edward III in 1348, and the Duchess of Cambridge, 40, made her royal debut at the prestigious event back in 2008 when she and Prince William were dating. William also received his Order of the Garter knighthood that year, so it was a momentous occasion.

Kate's appearance at the ceremony was a significant signal that she was being welcomed into the royal family fold. Kate and William, who began dating in 2003, met while studying at the University of St. Andrews. She and William tied the knot at Westminster Abbey three years later on April 29, 2011.

It was clear during her 2008 appearance that Kate, who wore a polka-dot black skirt suit and matching hat for the event, was already very comfortable with William's family as she chatted happily with Prince Harry and Camilla, Duchess of Cornwall.

The Order of the Garter ceremony has been a constant thread in their relationship. Less than two months after her royal wedding, Kate appeared at the event — this time riding in the carriage alongside her new husband.

And in 2014, Kate, in a pastel blue Christopher Kane coat dress, beamed at William who was caught giving her a sweet smile as he looked over at her during his parade to Windsor Castle.
