Kate Middleton and Prince William had several adorable twinning moments throughout their relationship.

In 2011, the Duke and Duchess of Cambridge both wore white cowboy hats during their trip to Calgary, Canada. In 2016, the royal couple once again wore matching clothes when they toured the Land Rover BAR boat shed at America’s World Cup Series in Portsmouth, England.

In the same year, Prince William and Middleton went on a tour of Canada. The couple visited Haida Gwaii, also known as the Queen Charlotte Islands. Before leaving the venue, they were gifted with matching Raven’s Tail scarves, and they wore it on their way back.

Shortly after Prince William and Middleton’s royal wedding in 2011, the parents of three once again went to Canada. They also visited the United States on their royal tour. Prince William and Middleton were made honorary members of the Canadian Rangers during their outing at Blatchford Lake, Northwest Territories.
