Kate Middleton and Prince William wore matching navy and red team shirts by Henri Lloyd at the America's Cup World Series, an international yacht sailing competition, in Portsmouth, England on Sunday, July 26. It was their first official royal engagement as a couple since Kate gave birth to Princess Charlotte.

Kate and William were all smiles as they greeted participants at the sailing event. The pair's couple shirts were embroidered with their titles "Duchess of Cambridge" and "Duke of Cambridge" on the back. Kate paired the shirt with matching skinny jeans and beige flat shoes. She tied her hair up in a voluminous ponytail. William, meanwhile, completed his look with black jeans and brown shoes.

Kate and William received special gifts for Charlotte and Prince George from Sir Ben Ainslie's Land Rover BAR racing team. The couple was presented with two jerseys printed by sisters Ella and Millie Morgan with Charlotte and George's names on them. They also got toys for their children, including wooden replicas of the Navy's two new aircraft carriers, the Queen Elizabeth and the Prince of Wales.

The event later was canceled due to the forceful wind. William joked to the guest at the event, "I think the whole plan has changed about 50 times since we arrived."
